Description

Label, system and method for forming a label

The present invention relates to a label, a system comprising such a label and a method for forming such a label.

Labels are used to prove origin or to provide information that can be requested if necessary. Electronic labels have conductor track structures that form, for example, a coil or antenna unit for RFID functionality. It is always a challenge to contribute to cost-effective production of the label and also to enable reliable and secure functionality for an intended application.

It is an object underlying the invention to provide a label which can be produced cost-effectively and which also enables reliable and safe functionality for the intended applications of the label.

The problem is solved by the features of the independent patent claims. Advantageous further developments are specified in the respective dependent patent claims.

According to one aspect of the invention, a label for forming a multilayer conductor track structure comprises a first label section and an adjacent second label section. The first label section has a first conductor track structure which comprises a plurality of conductor tracks which are electrically coupled to a first connection point by means of a further conductor track. The second label section has a second conductor track structure which comprises a plurality of conductor tracks which are electrically coupled to a second connection point by means of a further conductor track. The two conductor track structures are formed on or at a common carrier layer and can be arranged one above the other with respect to a stacking direction by means of folding along a fold line, so that a folded label can be formed. The label can be used to create a multi-layer conductor track arrangement in a simple and cost-effective manner, for example a coil or drilling protection arrangement. To create multiple functional layers, the label is simply folded along one or more fold lines to form a two- or multi-layer conductor track arrangement. Folding is therefore a cost-effective replacement compared to multiple printing and laminating steps to create layers lying one on top of the other.

The two conductor track structures are preferably formed on a common side of the carrier layer and can be folded towards and/or away from each other along the fold line. Thus, with respect to the stacking direction in the folded label, the two conductor track structures face each other and are surrounded by the carrier layer or face away from each other, so that the carrier layer is partially arranged between the two conductor track structures. Alternatively or additionally, one conductor track structure or a section thereof can be formed on an opposite side of the carrier layer relative to the other. For example, the first conductor track structure is formed on the top side and the second conductor track structure is formed on the bottom side of the carrier layer. An electrical coupling of the two conductor track structures can already be set up before folding and/or formed by folding and arranging the conductor track structures one above the other.

By means of folding, a large number of multi-layer label structures can be realized, which can be specified depending on the application. For example, the conductor track structures can be folded inwards and protected by the carrier layer. Alternatively, the conductor track structure can be folded outwards to be more easily accessible and easier to contact. The associated output label provides correspondingly specified conductor track structures, which are formed next to one another on the common carrier layer, in particular during a printing process. The carrier layer is designed, for example, as a paper or plastic element, for example as a PET film element, and provides a support structure for the conductor track structures. No different printing processes are required to provide several printing layers on top of one another. The label described thus provides an efficient way of forming an electrically conductive multi-layer structure. The conductor track structures each have, for example, several straight sections, each of which has a different main direction of extension to adjacent further sections and is mainly described in this description as a conductor track of the associated conductor track structure. If the conductor tracks or the conductor track sections are connected to one another, the sections can alternatively also be viewed as just one connected conductor track of the conductor track structure. In addition, individual or all conductor tracks or conductor track sections of a conductor track structure can also be non-straight.

It is a finding in connection with the present invention that conventional arrangements for multi-layer labels, for example, comprise a printing process for applying conductive structures to a substrate and then overprinting with an insulating layer, on which in turn another layer of a conductive structure is printed in order to form a multi-layer label with conductive structures. Each individual printing layer requires a separate pass through a printing machine and requires corresponding time and costs. In addition, with such conventional label arrangements it may be necessary to print an insulating varnish two or more times per layer in order to avoid waste due to short circuits. Such process steps cause additional time and material expenditure and increase the manufacturing costs. With regard to an application for producing a conventional drilling protection film, a particularly high level of precision is also required, which is difficult to ensure with multiple overprinting, so waste and further costs must be taken into account.

Alternatively, a conventional arrangement can be realized by printing several conductive structures on several substrates and then arranging and laminating the individual printed substrates one on top of the other. Several printed layers of functional materials on top of each other result in higher cumulative production costs and contribute to a certain amount of material waste. However, even in such label structures, each individual printed layer requires a separate pass through a printing machine. In addition, contacts must be made between individual film layers. Such through-plating requires, for example, the production of holes or openings, which are subsequently filled with conductive Materials such as silver or carbon paste must be filled. This means that additional work steps with a very high level of precision are required. Again, with regard to an application for producing a conventional drilling protection film, it is very difficult to ensure that the film is laminated to a precise fit. In addition, different parameters such as different film batches, different influences on substrates during different production steps, such as different silver batches or different screens and different production times, have a negative impact on the precision when laying conductor track structures on top of one another and thus result in increased production waste.

Using the foldable label structure described, time-consuming multiple printing and laminating processes can be eliminated, and time and material expenditure as well as production costs can be kept low. A multi-layered conductor track structure can be created by printing the label sections side by side once and then folding them over one another. The conductive connections of the individual label sections can be printed at the same time without any additional effort. In particular, time-consuming through-plating after laminating can be eliminated. Costs can be reduced because only one or at least fewer printing steps are required. In addition, identical conditions when producing the individual label sections contribute to high precision when laying one on top of the other and also reduce label waste.

According to a further development, the conductor tracks of the first conductor track structure and the second conductor track structure are formed in a meandering shape, so that the label is designed to form a multi-layer drilling protection arrangement in a folded state. In particular, the conductor tracks of the first conductor track structure can be oriented transversely to the stacking direction in relation to a lateral direction of the label, parallel to and offset from the conductor tracks of the second conductor track structure. Alternatively or additionally, the fold line between the two conductor track structures, which are arranged one above the other after folding, can be arranged asymmetrically, so that when folding, for example, the conductive conductor tracks of the first conductor track structure on one side of the carrier layer are above the gaps between the conductor tracks of the second conductor track structure. come to rest on the opposite side of the carrier layer and form a closed surface in the projection. Thus, the conductor tracks of the first and second conductor track structure, for example in relation to a top view, create a continuous protective surface that cannot be passed through without damage using a micro drill.

The conductor tracks of the first and second conductor track structures can be printed adjacent to one another with respect to a projection within a common plane or can be designed such that they overlap one another in sections along a lateral direction of the label. If the conductor tracks of the first and second conductor track structures are designed to be straight and parallel, for example, the folded label then results in a strip-shaped overlap of adjacent conductor tracks of the first and second conductor track structures with respect to a top view, which corresponds to a projection within a common plane. The conductor tracks of the first and second conductor track structures can alternatively be designed such that they are oriented obliquely or perpendicular to one another. The conductor tracks of the first and second conductor track structures then form a grid structure with several overlapping sections, for example with respect to a top view along the stacking direction.

Payment information that is temporarily stored on a card payment reader is of interest to unauthorized persons, such as thieves or hackers. It is therefore urgently necessary to improve the security of such card payment readers in order to prevent unauthorized access. Among other things, unauthorized persons try to gain access to the payment information on a card payment reader using an instrument, for example a micro drill or a laser. Using such a micro drill, microscopically small holes can be made in the housing of the card payment reader through which the stored payment information can be read.

The described label enables the formation of a drilling protection arrangement, which is attached, for example, inside the card payment reader, and provides reliable protection against such an access attempt and can contribute to improving the security of such card payment readers. The Connection points of the label or the drilling protection arrangement are signal-coupled to the electronics of the device to be protected, and if the conductor tracks are damaged by an unauthorized attempt at access, the stored data of the electronic device is immediately deleted. Thus, using the label described, a drilling protection arrangement can be provided in a simple and cost-effective manner, which provides reliable protection for stored data of an electronic device. In an initial state, the drilling protection arrangement can be printed on a common label web in particular and, as a folded label, can create a layer stack with a plurality of printed functional layers and be referred to as a drilling protection element or drilling protection film. The drilling protection arrangement can reliably protect electronic devices against unauthorized access. To protect the conductor track structures, one or more protective lacquer layers can be provided, which cover the conductor track structures in sections or completely as an alternative or in addition to insulation layers.

The label can also be designed such that the conductor tracks of the first conductor track structure are designed in a meandering shape and surround each other in a spiral, and/or the conductor tracks of the second conductor track structure are designed in a meandering shape and surround each other in a spiral, so that the label is designed to form a multi-layer coil arrangement in a folded state. For example, the first and the second conductor track structure each comprise a connection point which is surrounded by the respective conductor tracks in a meandering and spiral shape and which is electrically coupled to the associated connection point by means of a respective further conductor track.

The respective conductor track structures can be designed such that an electrical coupling of the respective conductor track structures is set up before and/or after folding. For example, the label is designed such that the first and the second conductor track structures are electrically coupled to one another both before and after folding along the fold line. This can be realized in particular by a connecting conductor track that extends between the first and the second label section and electrically connects the two conductor track structures to one another. If the fold line between the label sections, the connecting conductor track accordingly crosses the fold line at least once.

Alternatively or additionally, the label can be designed such that the first and the second conductor track structure each comprise one or more connecting sections and are designed such that they are spaced apart from one another before folding and are electrically coupled to one another after folding along the fold line by means of the connecting sections. The connecting sections are designed to be coordinated with one another in terms of position and geometry so that they come into contact with one another after folding and establish a reliable electrical coupling of the respective conductor track structures. In particular, connecting sections assigned to one another are designed with respect to the stacking direction such that together they have a predetermined height that is greater than a total height of conductor tracks of the first and second conductor track structures facing one another.

Alternatively or additionally, the label can be designed such that conductor track structures are formed separately from one another and are also separated in a predetermined manner after folding and, by means of their connection point or connection points, provide respective contact areas, for example for an electrical coupling with a conductor track or a connection of an external sensor or an external detector unit.

According to a further development, the label has one or more insulation layers that cover the first and/or the second conductor track structure at least in sections, so that they are arranged between opposing conductor tracks when the label is folded. Such insulation sections can be applied locally over predetermined conductor track sections or cover the entire surface of the first and/or the second label section or, if necessary, further label sections. For example, insulation sections are applied to the respective conductor track structures and cover associated conductor tracks up to a connection point and/or a connection point. One or more further conductor tracks can then be applied to such insulation sections. Alternatively or additionally, insulation sections can be provided specifically with regard to the folding of the label. The insulation layers are each designed to to prevent unwanted electrical connection between conductor tracks, especially in the folded, operational state of the label.

The label can further comprise a third label section and a fourth label section with a respective conductor track structure, each of which has a plurality of conductor tracks. The first to fourth conductor track structures are formed together on or on the carrier layer and can be arranged one above the other by means of folding along predetermined fold lines with respect to a stacking direction, so that a folded label can be formed in which the first to fourth conductor track structures are electrically coupled to one another and form respective conductor track layers of a multilayer conductor track arrangement.

The label can be designed in such a way that between two conductor track structures in the area of a respective fold line, a predetermined curved conductor track is formed on the carrier layer, which crosses the associated fold line several times and electrically connects the two conductor track structures to one another. Alternatively or additionally, the label can have between two adjacent conductor track structures in the area of a respective fold line, a predetermined thick or wide conductor track on the carrier layer, which crosses the associated fold line and electrically connects the two conductor track structures to one another.

A conductive connection between the layers or label sections of the label can thus be implemented in various variants and protected from damage caused by folding. A conductor track in the form of a simple line can lead, for example vertically, over the fold edge. Alternatively or additionally, an electrically connecting conductor track can be formed on or within the fold line, which is preferably thicker or wider than other conductor tracks next to the fold line. Alternatively or additionally, a meandering conductor track along the fold edge can establish an electrically conductive connection between two conductor track structures, so that the meandering conductor track is alternately located to the left and right of the fold edge. Alternatively or additionally, an electrical connection can be established by a predetermined design of surfaces or pads in and around the fold line, which come to lie on top of one another when folded and above them the make electrical contact. Such opposing connecting elements or connecting sections can have an electrically conductive adhesive on an upper side so that they contact each other after folding and are adhesively connected to each other.

According to a further development of the label, one or more spacers are formed on the carrier layer between two conductor track structures in the area of a respective fold line, which spacers have a predetermined height and limit a maximum folding of the label. The spacers can in particular counteract damage to the electrical connecting conductor track that crosses the fold line, so that, for example, the first label section cannot be folded 180° towards or away from the second label section. The spacer(s) thus form a curvature limitation in the area of the associated fold line in order to prevent the connecting conductor tracks from bending too sharply at the fold edge. Such spacers can be formed, for example, by dispensing or printing dots or lines of varnish or of curable adhesive on and/or at the fold line.

According to a further development of the label, for example, the first conductor track structure has a free end section with an associated connection point at each end that is opposite in terms of signal technology. Alternatively or additionally, the second conductor track structure can have a free end section with an associated connection point at each end that is opposite in terms of signal technology. The conductor track structures each comprise a plurality of interconnected conductor tracks that form, for example, a continuous conductor track strip with changes in direction. The respective ends of such a conductor track strip can be referred to as opposite ends in terms of signal technology, since a signal would run from one end to the other end.

The conductor track structures can also be applied as separate components to the material web of the label, so that they are separated in a predetermined manner even after folding and provide corresponding contact areas for electrical coupling via their respective connection points. Such electrical coupling can, for example, when using the label, the process can be carried out by coupling one or more connection points with electronic components. This makes it easy and cost-effective to create a multi-layer conductor track arrangement, which, for example, sets up a coil or drill protection arrangement that can later be further processed and electrically contacted with connection components.

Furthermore, the conductor track structures and their respective connection point or connection points can be formed in relation to existing fold lines on a common label section or on different label sections. The fold lines separate, for example, adjacent label sections from one another, so that, for example, the first conductor track structure with one or more connection points and the second conductor track structure with one or more connection points are formed in relation to an intermediate fold line on different label sections.

For example, the label can be designed for a payment terminal in such a way that each layer of the label or each label section preferably comprises two or more contact loops in the form of respective conductor track structures, each of which has two connection points. Four connection points would thus be provided per label section, which are not coupled, for example, but each set up a separate forwarding to a respective contact of the security chip of the payment terminal. The security chip or the payment terminal are then set up in such a way that damage to just one contact loop leads to data deletion in the payment terminal.

According to a further development of the label, a fold line is provided between a respective conductor track structure and an associated connection point, so that the respective connection point can be arranged above or below the respective conductor track structure in the folded label with respect to the stacking direction. For example, the first conductor track structure is arranged on a first label section, the second conductor track structure on a second label section and their respective connection points on a third label section, with a fold line being introduced or a fold being provided between adjacent label sections. In the folded Label, the first conductor structure and the second conductor structure can be folded over each other and their respective connection points can then be folded up or down and thus arranged above or below the respective conductor structures.

By separately arranging one or more connection points on a different label section than that on which the associated conductor track structure is formed, a connection lug can also be set up, which can be folded out with the connection point or connection points located thereon if required and made more easily accessible for electrical coupling. For example, the respective connection points of the first and second conductor track structure can be arranged together on a label section or on different label sections and form one or more predetermined protruding connection lugs by folding along an associated fold line. Such a connection lug can, for example, be designed so that it can be folded off and reattached in sections from the rest of the folded label using a pressure-sensitive adhesive.

The separate conductor track structures can be contacted with a common or with different connection components. A connection point of a conductor track structure can also be electrically coupled to another conductor track structure, so that it is also possible to couple the separate conductor track structures to one another at a later point in time if required. This means, for example, that the existing conductor track structures can be supplied with power independently of one another. The respective connection points are preferably designed as connecting contacts with a much larger surface area than the relatively finely printed conductor tracks and/or have a much higher or thicker extension in the stacking direction. Because the connection points can be arranged separately between and/or under or over the respective conductor track structures, they can be reliably protected against manipulation in the label.

In particular, with regard to an embodiment in which the spatial arrangement of the connection points as connecting contacts between the layers of the printed Conductor track structures is possible, a particularly reliable protection against tampering can be created simply by folding and gluing. For example, opposite label sections are connected to the first and second conductor track structures by means of one or more material strips, which can be viewed as a third label section in between. The respective connection points of the associated conductor track structures can be formed on the material strip or strips, between which a fold line is introduced or a fold is provided. In this way, internal or external contact points can be set up by means of folding. For example, a design of the folded label with internal contacts does not require contacting outside of the printed layers, for example by means of pressure contacts directly from above or by means of an adapter to such contact points of the printed flat layers or by means of lateral derivation, for example to a plug connection. Accordingly, a particularly tamper-proof design of the label can be realized.

The label described can be implemented in a variety of embodiments in which the conductor track structures are electrically connected to one another, can be connected to one another during the folding process or, alternatively, are arranged separately from one another after the folding process. Using one or more additional folding lines and/or slits, separate connection lugs and/or contact zones with one or more connection points can be formed on the inside or facing outwards.

According to a further aspect of the invention, a system comprises an object, for example in the form of an electronic device or an RFID functionality, and an embodiment of the previously described label arranged in or on the object. For example, the label in its initial form forms a foldable arrangement for setting up a drill protection, so that in an electronic device, such as a card payment reader, the folded label sets up a multi-layer drill protection arrangement in or on the electronic device. Alternatively, the label can be intended to realize a foldable arrangement for setting up a coil structure in its initial form, so that the folded label provides, for example, a multi-layer coil arrangement for an RFID antenna. Because the system comprises an embodiment of the described label, properties and features described in connection with the label are also disclosed for the system and vice versa.

According to a further aspect of the invention, a method for forming an embodiment of the previously described label comprises providing a carrier layer and applying or attaching a first conductor track structure with a plurality of conductor tracks on or to the carrier layer in a first label section. The method further comprises applying or attaching a second conductor track structure with a plurality of conductor tracks on or to the carrier layer in a second label section. The method further comprises applying or attaching a first connection point and a second connection point on the carrier layer. In addition, the method comprises applying or attaching a respective conductor track which is designed to electrically couple the first conductor track structure to the first connection point and the second conductor track structure to the second electrical connection point. The two conductor track structures are formed on or on the common carrier layer and can be arranged one above the other with respect to a stacking direction by means of folding along a fold line, so that a folded label can be formed in which the first and second conductor track structures are electrically coupled to one another. In particular, the conductor tracks of the first and the second conductor track structure are formed in a meandering and/or spiral shape, so that after folding the label along the fold line F, the first and the second conductor track structure are arranged one above the other and thereby form a multi-layer drilling protection arrangement and/or a multi-layer coil arrangement.

Because the respective method is designed in particular for producing an embodiment of the previously described label, properties and features of the label are also disclosed for the production method and vice versa. The conductor track structures, connecting conductor tracks and/or connection points and/or connection points can be formed in particular in a common printing process. Alternatively, separate printing processes can be carried out.

The label can be formed on a web of material with respect to a plurality of anti-drill or reel arrangements and provided as a label or film roll A large number of labels can be processed in a roll-to-roll process with a pre- and post-run. A material web for the carrier layer can be provided, processed and printed in order to form a large number of the labels described. Punching and/or cutting processes can also be carried out, for example to carry out format and/or functional punching of individual or multiple layers of the label. Furthermore, one or more insulation layers can be provided as material rolls and processed at the same time in order to electrically isolate conductor tracks from one another. Such roll production is made possible in particular by the fact that the label can be formed essentially completely printed and provides useful flexibility. The unfolded labels can be separated from such a label roll and folded if required in order to form the folded label with the multi-layer conductor track structure.

Because all the required label layers can be printed next to each other in the same operation, the number of machine runs can be reduced. The conductor track structures and conductive connections of the individual label sections can be printed next to each other, so that subsequent and complex through-plating can be avoided even for label structures with more than two layers. By folding, a high level of precision can be achieved when placing the conductor track structures on top of each other, since differences in several parameters, such as different film batches, different influences on substrates during different production steps, such as different silver batches, different screens and different production times, are eliminated or avoided by the foldable label.

Even if the label is intended to form a two- or multi-layer conductor track structure when folded, the respective conductor track structures can be printed next to each other and arranged on both sides by folding them over. If, for example, four label sections and associated conductor track structures are intended, two conductor track structures can be printed next to each other and arranged on top of each other by folding them lengthways and crossways. In relation to a top view of such an output label, the conductor track structures are on the right and left and printed next to each other at the top and bottom. Furthermore, a slit or punch can be provided between two label sections so that various folding options can be implemented. In addition, the label can also be designed in such a way that not all of the existing conductor track structures and/or label sections are folded over each other. At least two conductor track structures are placed on top of each other by means of folds.

In the following, embodiments of the invention are explained using schematic drawings. They show:

Figures 1-9 show embodiments of a label for forming a multilayer coil arrangement in different views,

Figures 10-18 show embodiments of a label for forming a multi-layer drilling protection arrangement in different views,

Figure 19 is a flow chart for a method for producing the label with a multilayer conductor track structure, and

Figures 20-37 show further embodiments of the label for forming a multi-layer coil or drill protection arrangement in different views.

Elements or features of the same construction or function are identified with the same reference symbols throughout the figures. For reasons of clarity, not all elements or features shown may be identified with corresponding reference symbols in all figures.

Figures 1-9 show embodiments of a label 1, 10 for forming a multilayer coil arrangement in different views. The label 1, 10 comprises a first label section 11 with a first conductor track structure 51, which has a plurality of conductor tracks 5, which are electrically coupled to a first connection point 61 by means of a further conductor track 6. The label 1, 10 further comprises an adjacent second label section 12 with a second conductor track structure 52, which comprises a plurality of conductor tracks 5, which are electrically coupled to a second connection point 62 by means of a further conductor track 6. The two conductor track structures 51, 52 are formed on a common carrier layer 2, for example printed in the form of a conductive paste, and can be arranged one above the other with respect to a stacking direction R by folding along a fold line F, so that a folded label 1 can be formed in which the first and second conductor track structures 51, 52 are arranged one above the other and electrically coupled to one another.

The conductor tracks 5 of the first conductor track structure 51 are designed in a meandering shape and run outwards or inwards in a rectangular spiral. The conductor tracks 5 of the second conductor track structure 52 are also designed in a meandering shape and run outwards or inwards in a rectangular spiral. The conductor track structures 51, 52 form respective coils which are arranged one above the other in a folded state. The first conductor track structure 51 and the second conductor track structure 52 each comprise a connection point 41, 42 which are surrounded by the respective conductor tracks 5 in a meandering and spiral shape and which are electrically coupled to the associated connection point 61, 62 by means of a respective further conductor track 6. The conductor tracks 5 and 6 are electrically conductive connections and can be designed the same or different in terms of shape and/or material. The conductor tracks 5 and 6 are arranged offset from one another along the stacking direction R and are electrically separated by an insulation layer 3 (see Figures 3 and 4). A current direction in the conductor tracks 5, 6 arranged one above the other effectively runs essentially in the same direction. The conductor tracks 5 conductor track structures 51, 52 can be arranged with respect to lateral directions LI, L2 such that they are offset from one another in a folded state along the lateral directions LI and/or L2 or not.

In this description, the label 10 refers to a predominantly flat, unfolded initial label that extends essentially along the lateral directions LI and L2. The conductor track structures 51, 52, 53, 54 are formed next to one another on the upper side on the carrier layer 2. In this description, the label 1 refers to the folded state that is formed by folding the label 10. If the label 10, as illustrated in Figures 1-4, is formed essentially symmetrically with respect to the two label sections 11 and 12, The folded label 1 accordingly has twice the height or thickness along the stacking direction R as the unfolded original label 10.

The conductor track structures 51, 52, 53, 54 each have a plurality of straight sections, which are each regarded in this description as a conductor track 5 of the associated conductor track structure 51, 52, 53, 54. Since the conductor tracks 5 are connected to one another, it can alternatively be stated that a respective conductor track structure 51, 52, 53, 54 comprises only one continuous conductor track with changes in direction and a plurality of sections. In addition, individual or all conductor tracks 5 can also be non-straight. For example, the conductor track structures 51, 52 shown in Figures 1 and 2 can be meander-shaped and/or spiral-shaped and/or circular.

Figure 2 shows in a top view that the label 10 can also be completely covered with an insulating layer 3 and/or can have one or more insulating layers 31-33 that cover conductor tracks 5, 6 in a predetermined manner. The insulating layers 3, 31-33 are intended to prevent undesired contact between conductor tracks 5, 6 on the output label 10 and, in the folded state, on the label 1. According to Figure 1, for example, it is useful to apply an insulating layer 31, 32 between the conductor tracks 5 and 6 in relation to the unfolded state of the label 10. Insulation can be formed by separate sections or a continuous insulating layer 3. It can be separated or slit in the area of the fold line F to enable tighter folding, or it can be continuous in order to deliberately not place too much stress on a fold edge and to mechanically protect the crossing conductor tracks 5, 6. Furthermore, it can be useful to apply a third insulation layer 33 to the first or second label section according to Figures 1 and 2 if the label 10 is intended, for example, to be folded inwards. The correspondingly folded label 1 is shown in Figure 4. The two connecting conductor tracks 6 are thus protected from undesirable contact with one another in the folded state.

Alternatively or in addition to a middle insulation layer 33, a design of the label 10 can be formed such that in a folded state it does not form a Contact of the conductor tracks 6 with themselves and/or with one another. This is made possible, for example, by the fact that the label 10 according to Figures 1 and 2 has an alternative course of the conductor tracks 6. The conductor track 6, which connects the first connection point 41 with the first connection point 61, can alternatively be guided slightly upwards or downwards on the fold line F, so that the straight sections are offset from one another perpendicular to the fold line F. In a folded state towards one another, they would then not be arranged directly on top of one another, but offset from one another. Alternatively or in addition to a middle insulation layer 33, spacer elements can also be provided which set up a certain minimum distance between the conductor track structures 51, 52 folded towards one another, so that undesired contact is avoided. If the label 10 is intended, for example, for the conductive structures to be folded outwards, no intermediate insulation layer 33 is required, since the conductor track structures 51, 52 and their associated further conductor tracks 6 are separated from one another by the carrier layer 2 (see Figure 3). The side views of the folded label 1 shown in Figures 3 and 4 each show a view looking along the lateral direction LI. The second connection point 62 is therefore located behind the first connection point 61.

It should be noted that the conductor tracks 6 are only shown in dashed lines in the figures in order to be able to distinguish them from the conductor tracks 5 of the respective conductor track structures 51-54. They usually form continuous conductor track strips, so that both the conductor tracks 5 and the connecting conductor tracks 6, which optionally connect the conductor tracks 5 to a respective connection point 61, 62, each provide reliable electrical conductivity. They each form conductive layers, which are printed on the carrier layer 2 with a predetermined course using an electrically conductive paste, for example.

Figures 1-4 show a structure of the label 1, 10, with which a two-layer coil arrangement can be realized. Figures 5-9 show a structure of the label 1, 10, with which a four-layer coil arrangement can be realized. The label 1, 10 accordingly has a first to fourth label section 11-14 and a first to fourth conductor track structure 51-54, which are assigned to a respective label section 11-14. Furthermore, a first to fourth connection point 41-44 is provided, which can be connected by means of further conductor tracks 5 or 6 are connected to one another or to the two connection points 61, 62. Alternatively, a three-layer or a five- or multi-layer coil arrangement can be formed by designing the label 1, 10 with corresponding label sections and conductor track structures as well as folding lines.

The folding lines F, F1-F2 can have predetermined structures, such as perforations or embossed/folded lines, to simplify folding, thus contributing to reliable and orderly folding of the label 10. Alternatively, the respective folding line F, F1-F2 in the figures merely represents an auxiliary line along which the label 10 should be folded. The folding lines F, F1-F2 therefore do not necessarily have to be formed as structures in or on the carrier layer 2 of the label 1, 10.

According to Figure 5, the two fold lines Fl, F2 enable the output label 10 to be folded twice. The label 10 can be designed in such a way that a sequence is predetermined or recommended, so that, for example, it is first folded along the first fold line Fl and then along the second fold line F2. This can involve folding inwards or outwards in each case. Figure 6 shows a schematic side view of a first folded state of the label 10 according to Figure 5, in which it has been folded outwards around the first fold line Fl, so that the conductor track structures 51 and 54 face away from the other two conductor track structures 52 and 53 or are separated by the carrier layer 2. Figure 6 shows a side view looking opposite to the lateral direction L2 according to Figure 5. The fold edge is thus arranged on the opposite side of the open label edge, which is shown in Figure 6. Further folding along the fold line F2 enables the formation of the label 1, as schematically illustrated in Figure 7. Thus, the first and fourth conductor track structures 51, 54 are arranged on the inside and face each other, while the second and third conductor track structures 52, 53 are arranged on the outside and face each other. If necessary or useful, an insulation layer can be arranged between the first and fourth conductor track structures 51, 54, which, for example, as one or more segments on the output label 10 according to Figure 5, completely or partially covers the first and/or fourth label section 11, 14. Figure 8 shows a further possibility for forming the folded label 1 with a multi-layer coil arrangement. Starting from the label 10 according to Figure 5, for example, first the third and fourth label sections 13, 14 are folded around the fold line F2 towards the other two label sections 11, 12. The label 10, which has been folded once, is then folded around the further fold line Fl, so that essentially the first and second label sections 11, 12 are folded towards each other. Thus, all conductor track structures 51-54 are arranged safely and reliably within the carrier layer 2 and are protected to a certain extent from external influences.

Figure 9 shows a further embodiment of the output label 10, which has an elongated initial shape, while that of the output label 10 according to Figure 5 is more square. The label 10 according to Figure 9 can also be used to provide a variety of possible folding variants in order to form a multi-layer coil arrangement. An order can but does not have to be predetermined, so that each folding line can be used first and then the remaining folding lines can be used to form a final state of the folded label 1 from the output label 10. For example, the output label 10 according to Figure 5 can be folded around the two folding lines Fl, F2. The folding lines Fl, F2 each allow folding upwards and downwards, so that there are eight folding options to form the double-folded label 1.

Another embodiment of the output label 10 is shown in Figure 5a, which has a slit S between two adjacent label sections 11 and 14 in order to provide even more folding options. The slit S implements a predetermined section-by-section separation of the carrier layer 2, so that the first label section 11 and/or the fourth label section 14 can be folded upwards or downwards individually or independently of one another along the fold lines Fl. The structure according to this embodiment is similar to the output label 10 according to Figure 5, with the difference that the conductor track structures 51 and 54 are designed accordingly with regard to the slit S. Accordingly, in comparison to Figure 5, the second connection point 62 is moved to the fourth label section 14, so that no conductor track crosses the slit S. Accordingly, the conductor track structures 51 and 54 can be folded upwards or downwards individually due to the slit S. are folded, while according to Figure 5 two conductor track structures 51-54 are each folded together around the fold line Fl or F2.

For example, according to Figure 5a, the first label section 11 with the first conductor track structure 51 can be folded around the first fold line Fl to the left onto the second conductor track structure 52. This folding can be done in such a way that the first conductor track structure 51 is then facing or facing away from the second conductor track structure 52. Alternatively or additionally, the fourth label section 14 with the fourth conductor track structure 54 can be folded around the first fold line Fl upwards or downwards or, according to the top view in Figure 5a, to the left towards the third conductor track structure 53. In addition, such a local slit can also be provided at other positions of the label 1, 10 in order to provide desired folding options. The respective conductor track structures 51-54 are then to be designed accordingly in coordination with a slit. In this case, connecting sections 57 can also be used if necessary, as explained below with reference to Figure 17.

Figures 10-18 show embodiments of the label 1, 10 for forming a multi-layer drilling protection arrangement in different views. Figures 10-18 each show a structure of the starting label 10 with two label sections 11, 12, so that the folded label 1 can set up a two-layer drilling protection arrangement. Alternatively, however, three or more label sections can also be provided, which set up respective layers in the folded label 1.

The conductor tracks 5 are each predominantly formed in a meandering shape. The first conductor track structure 51 is electrically connected to the first connection point 61 by means of a conductor track 5, 6. The second conductor track structure 52 is electrically connected to the second connection point 62 by means of a conductor track 5, 6. The two conductor track structures 51, 52 are also coupled to one another by means of the conductor tracks 5. Thus, two conductor tracks 5, 6 cross the fold line F. Figures 11 and 12 show possible configurations of the folded label 1 when viewed along the lateral direction LI. If the conductor track structures 51, 52 are folded inwards towards one another, an insulating layer 3 lying between them is useful. The conductor tracks 5 of the first and second conductor track structures 51, 52 are preferably within the lateral plane L1-L2 are offset from one another so that in the folded state they form a continuous surface, as illustrated in the schematic plan view in Figure 13. Alternatively or additionally, the fold line F can be arranged asymmetrically between the conductor track structures 51, 52. In this way, a continuous conductor surface can be formed in relation to a plan view, which cannot be passed through without causing damage in the event of an attempt at manipulation or access using a micro drill.

Figures 14 to 18 show further embodiments of the label 10 for forming a two-layer drilling protection arrangement. The transition between the label sections 11, 12 and the conductor track structures 51, 52 is different in each case. This is so that the conductor tracks 5 that cross the fold line F are not subjected to excessive stress when folded and damage caused by folding is avoided and an associated risk is at least reduced. The conductor tracks 5 or conductor track sections crossing the fold line F can, for example, run within the fold line F (see Figure 14). Alternatively or additionally, the respective conductor track 5 can be designed to have a predetermined thickness or width within or next to the fold line F, so that it is thicker or wider than neighboring conductor tracks 5 of the meander structure (see Figure 15). Alternatively or additionally, the respective conductor track 5 can be designed to be curved or wave-shaped so that it crosses the fold line F several times (see Figure 16). Each crossing is preferably not perpendicular but diagonal to the fold line F, so that the risk of damage caused by bending or folding is reduced.

Alternatively or additionally, a respective conductor track structure 51-54 can comprise one or more connecting sections 57, as illustrated in Figure 17. The connecting sections 57 are designed, for example, as relatively large surfaces or pads on or around the fold line F and come to lie on top of one another when the label sections 11, 12 are folded over, thereby establishing an electrical contact. The connecting sections 57 are designed to be higher than the adjacent conductor tracks 5, in particular with respect to the stacking direction R, so that they can establish a reliable electrical contact in the folded label 1. Preferably, a conductive adhesive is applied to an upper side of one or both connecting sections 57, which are coupled to one another, which leads to a particularly reliable electrical According to Figure 17, adjacent conductor track structures 51-54 are not necessarily electrically coupled to one another before the label 10 is folded, but at the latest after folding in an operational state of the label 1.

Alternatively or additionally, the respective conductor track 5 which crosses the fold line F can also be protected by providing spacers 58 which are applied, for example, as printed structures on and/or next to the fold line F on the carrier layer 2. Such spacers 58 can be particularly useful or provided when the label 10 is to be folded inwards in order to form the label 1.

The possibilities described with reference to Figures 14-18 for setting up kink protection or a reduced risk of damage for the conductor tracks 5 crossing the fold line F can also be applied to the previously described coil arrangements. Furthermore, the connecting conductor tracks 6 can also be designed accordingly if this is useful in the application.

Figure 19 shows a flow chart for a method for producing an embodiment of the output label 10 or the folded label 1 with a multi-layer conductor track arrangement for forming a coil or

B ear protection arrangement .

In a step S1, the carrier layer 2 is provided, for example as a film element.

In a step S2, the conductor track structures 51-52 or 51-54 with a respective plurality of conductor tracks 5 are applied, in particular printed, to the carrier layer 2 in the respective label section 11-12 or 11-14. Additionally or in a further step, intended connection points 41-44 and/or the connection points 61-62 can be formed on the carrier layer 2. Accordingly, for example, a design of the label 10 according to Figures 10 or 14-18 can already be formed. Any thicker or curved Conductor tracks 5, 6 and/or connecting sections 57 and/or spacers 58 can be printed at the same time.

Optionally, in a step S3, one or more insulation layers 3, 31-33 can be applied to one or more of the formed conductor track structures 51-52 or 51-54.

If provided, in a further step S4, connecting conductor tracks 5, 6 can be applied to the insulation layer(s) 3, 31-33, which are designed to electrically connect the first conductor track structure 51 to the first connection point 61 and the second conductor track structure 52 to the second electrical connection point 61. Thus, for example, a design of the label 10 according to Figures 1-2, 5 or 9 can be formed.

Optionally, in a further step S5, one or more fold lines F, F1-F3 can be formed in or on the carrier layer 2. Alternatively, the carrier layer 2 is already provided with the desired fold lines F, F1-F3 in step S1.

In one or more further steps, the folds can be carried out along existing fold lines F, F1-F3 to form the folded label 1. The folded label 1 can further comprise one or more adhesive layers which hold a folded state of the label 1 together and/or are provided for simple and reliable attachment of the label 1 to a substrate.

Thus, by folding, the label 1 can be produced with a two- or multi-layer structure of printed conductor track structures 51-52 or 51-54. The multi-layer structure of the label 1 can be produced in different designs depending on the type of folding. Adjacent conductor track structures 51-54 are electrically connected to one another by a printed conductor track 5 or 6. To protect the connecting conductor tracks 5, 6 during folding and to avoid electrical interruptions due to mechanical stress, the connecting conductor track 5, 6 in the area of the associated fold line F, F1-F3 is preferably printed over a larger area and/or thicker or wider and/or spacers 58 can be used as mechanical protection. Alternatively or in addition to a connecting conductor track 5, 6, electrical contact between conductor track structures 51-54 folded towards one another can also be made via electrical contact points, as represented by the connecting sections 57.

Figures 20-37 show further embodiments of the label 1, 10 for forming a multi-layer drilling protection arrangement in different views. Figures 20-29 show different embodiments of the label 1, 10, in each of which one or more connection points 61-64 of an associated conductor track structure 51, 52 are arranged on the outside of a label section 13, 14.

In the embodiment according to Figure 20, the first conductor track structure 51 is formed on a first label section 11 and the second conductor track structure 52 on a second label section 51. The conductor track structures 51 and 52 are electrically connected by means of a conductor track 5 which crosses the first fold line Fl. The connection points 61 and 62 of the first and second conductor track structures 51 and 52 are formed on a common third label section 13 and are electrically connected to the associated conductor track structure 51, 52 by means of a respective conductor track. A folded label 1 can thus be realized in which a connection lug 70 with the connection points 61, 62 located thereon can be formed (see Figures 21-23).

According to Figure 21, the conductor track structures 51, 52 are arranged one above the other, folded away from each other around the fold line Fl. The third label section 13 is folded with the connection points 61, 62 around the second fold line F2 towards the second conductor track structure 52. The third label section 13 can accordingly form a connection lug 70. In this context, it is pointed out that existing lines or overlaps in the fold areas are only visible in this and other figures due to the simplified preparation of the illustrated representations of the folded label 1.

According to Figure 22, the conductor track structures 51, 52 are arranged one above the other, folded towards each other around the fold line Fl. For electrical insulation, the insulation layer 3 is arranged between the conductor tracks 5 of the first and the second conductor track structure 51, 52. The third label section 13 is connected to the connection points 61, 62 around the second fold line F2 is folded back onto the second conductor track structure 52. In comparison to Figure 21, the conductor tracks 5 and the connection structures 61, 62 are now separated from the conductor tracks 5 of the second conductor track structure 52 by two layers of the label 10, which are formed by the second and third label sections 12, 13. The third label section 13 can again form a connection lug 70.

Figure 23 shows an embodiment of the folded label 1 according to Figure 22, in which the connection lug 70 is folded in or in which no connection lug 70 is provided.

In the embodiment according to Figure 24, the first conductor track structure 51 is formed on a first label section 11 and the second conductor track structure 52 on a second label section 51. The conductor track structures 51 and 52 are not electrically connected to one another. The first conductor track structure 51 essentially surrounds the second conductor track structure 52. Both conductor track structures 51, 52 each have a contact area with a respective connection point 61-64 at their signal-technically opposite ends, which form a respective end section of the associated conductor track structure 51, 52. The connection points 61 and 63 of the first conductor track structure 51 and the connection points 62 and 64 of the second conductor track structure 52 are formed on the common third label section 13 and are electrically connected to the associated conductor track structure 51, 52 by means of a respective conductor track. Thus, a folded label 1 can be realized, as shown in the side view according to Figure 25. Optionally, the third label section 13 can again be set up in such a way that a connection lug 70 with the connection points 61-64 located thereon can be formed (see Figures 21 and 22).

Figure 26 shows a further embodiment of the output label 10 with electrically unconnected conductor track structures 51 and 52. The first conductor track structure 51 is formed together with the connection points 61, 63 on the common first label section 11. The second conductor track structure 52 is formed on a second label section 12. The connection points 62 and 64 of the second conductor track structure 52 are formed on the common third label section 13 and are electrically connected to the associated second conductor track structure 52 by means of a respective conductor track, which each crosses the second fold line F2. In addition, the second label section 12 has connection recesses 90 on opposite sides along the fold line Fl, which are designed to match the connection points 61, 63 of the first conductor track structure 51. A folded label 1 can thus be realized, as shown in the side view according to Figure 27. Optionally, the third label section 13 can again be set up in such a way that a connection lug 70 with the connection points 62 and 64 located thereon can be formed (see Figures 21 and 22). The connection points 61 and 63 are also easily accessible in the folded label 1 due to the connection recesses 90 and can be reliably contacted.

Figure 28 shows a further embodiment of the output label 10 with electrically unconnected conductor track structures 51 and 52. The first conductor track structure 51 is formed on the first label section 11. The connection points 61 and 63 of the first conductor track structure 51 are formed on the common fourth label section 14 and are electrically connected to the associated first conductor track structure 51 by means of a respective conductor track that crosses the first fold line Fl. The second conductor track structure 52 is formed on the second label section 12. The connection points 62 and 64 of the second conductor track structure 52 are formed jointly on the third label section 13 and are electrically connected to the associated second conductor track structure 52 by means of a respective conductor track that crosses the second fold line F2. A folded label 1 can thus be realized, as shown in the side view according to Figure 29.

Optionally, the third and/or fourth label section 13, 14 can be designed such that a single connection lug 70 (see Figures 21 and 22) or a double connection lug 70 (see Figure 29) can be formed with the connection points 61, 63 and/or 62, 64 located thereon. The third and fourth label sections 13 and 14 each form outer label parts of the output label 10. In this context, it is pointed out that the third and/or fourth label sections 13 and 14 can also have a different shape, for example a rectangular or rounded shape.

The same applies to the label sections 11-14 of the other embodiments. Alternatively, in contrast to Figure 29, the fourth label section 14 can be folded upwards towards the first conductor track structure 51. Figure 29a shows a folding variant of the label 1 in which the fourth label section 14 is folded upwards and can set up a further connection lug 70. Figure 29b shows a folding variant of the label 1 in which the fourth label section 14 is folded inwards between the first label section 11 and the second label section 12 and allows, for example, lateral contacting of the connection points 61, 63.

If conductor tracks 5, which are not intended to contact one another in the folded label 1, are opposite one another, one or more insulation layers 3 are preferably provided. As an alternative to Figure 29, the two conductor track structures 51, 52 can be folded towards one another around the inner fold line F2. Furthermore, the outer third and fourth label sections 13, 14 can be folded towards one another around the respective outer fold lines Fl, F3, so that the connection points 61-64 of the conductor track structures 51, 52 are protected on the inside by the label layers of the third and fourth label sections 13, 14. The connection points 62, 64 of the second conductor track structure 52 are then preferably arranged between the connection points 61, 63 of the first conductor track structure 51. The connection points 61, 63 of the first conductor track structure 51 are accordingly to be designed at a corresponding distance from one another so that the connection points 62, 64 of the second conductor track structure 52 fit into the intermediate space.

Figures 30-37 show, in different views, a further embodiment of the label 1, 10, in which eight connection points 61-68 are formed, two of which are assigned to one of the four conductor track structures 51-54. The conductor track structures 51 and 52 are formed on the first label section 11, for example next to one another or adjacent to one another, so that a predetermined distance is set between the conductor tracks 5 of the two conductor track structures 51 and 52. The third and fourth conductor track structures 53, 54 can be formed on the second label section 12 in a corresponding manner. The third and fourth conductor track structures 53, 54 are preferably formed next to one another or adjacent to one another, so that a predetermined distance is set between the conductor tracks 5 of the two conductor track structures 51 and 52. The distance can be the same or different to the distance between the conductor tracks 5 of the first and second conductor track structures 51 and 52.

Each conductor track structure 51-54 has two contact areas each, which are configured by the connection points 61-68. For example, the connection points 61 and 62 are assigned to the first conductor track structure 51. The connection points 63 and 64 are assigned to the second conductor track structure 52, for example. The connection points 65 and 66 are assigned to the third conductor track structure 53, for example, and the connection points 67 and 68 are therefore assigned to the fourth conductor track structure 54. The connection points 61-68 are arranged internally on a central third label section 13, which is arranged between the first and second label sections 11, 12.

The first and third label sections 11, 13 are each delimited, for example, by the introduced or imaginary fold line Fl. The second and third label sections 12, 13 are each delimited, for example, by the introduced or imaginary fold line F3. The connection points 61-68 are arranged on the inside on a central third label section 13, which is set up between the first and second label sections 11, 12. The third label section 13 comprises four spaced-apart material strips, which are designed in particular in the form of a common material web of the starting label 10. Alternatively, the material strips are designed as separate label parts that are connected to the two further label sections 11, 12. Two of the eight connection points 61-68 are formed on each material strip at a distance from one another.

The fine conductive lines or conductor tracks 5 of the conductor track structures 51-54 provide protection for detecting physical attacks on the components to be protected with the label 1, 10. The conductor track structures 51-54 or the label sections 11, 12 can be glued together in use in order to fix the folded label 1 in its fold. For example, a label section 11, 12 or several label sections 11, 12 have an adhesive layer 80 on an underside (see Figure 31), which enables simple and reliable gluing to one another. The material strips The middle third label section 13 can also be provided with an adhesive layer or can be adhesive-free, adhesive-neutral or with weakened adhesive. At the actual contact points in the form of the connection points 61-68, there is preferably no adhesive bonding so that simple and reliable electrical contact can be established.

An adhesive or mechanical contact between the printed conductor track structures 51-54 and the respective label sections 11, 12 can, alternatively or in addition to other connection options, be made by a connection that is brought about by the adhesive force of the adhesive layer 80. With respect to the folded and glued label 1 (see Figures 35-37), the two label layers 11, 12 are reliably coupled to one another by means of the material-locking adhesive connection and the connection points 61-68 on the material strips can be securely arranged within the folded label 1 or set up outside the folded label sections 11, 12, for example to provide easier accessibility for subsequent electrical contact. If the two label layers 11, 12 glued together are moved from their position, for example if the object to be protected is manipulated, the tensile forces that arise cause the label sections 11, 12 and the conductor track structures 51-54 to separate from the non-glued connection points 61-68. Manipulation can thus be recognized or detected.

Figures 32-37 show possible folding processes along provided folding lines F1-F3, whereby not all folding lines F1-F3 have to be used. The order of the folding processes is also not necessarily specified and can be carried out in different ways in order to arrive at a respective folded label 1. For example, the starting label 10 according to Figures 30 and 31 can first be folded around the folding line Fl and then around the folding line F3, so that the first and second label sections 11, 12 with the associated conductor track structure 51-54 are angled away from the third label section 13 with the material strips (see Figure 32). The partially folded label can then be folded around the middle folding line F2, so that the material strips are each bent and moved towards each other (see Figures 33 and 34). In Figure 34, external supply lines or conductor tracks 92 are shown in arrow shape, with which the film structure of the folded label 1 can be contacted. Eight external conductor tracks 92 are indicated corresponding to the eight connection points 61-68. However, more or fewer conductor tracks 92 can also be connected to the connection points 61-68. A respective connection point 61-68 can be connected to one or more conductor tracks 92. Furthermore, depending on the application, one or more connection points 61-68 can also remain unconnected, for example, so that not all connection points necessarily have to be connected to a separate supply line.

Figure 35 shows the folded label 1 with a view of the first conductor track structure 51, which according to another embodiment could also have been folded inwards. The internal connection points 61-68 are relocated to an area protected against attacks and are thus more reliably protected. Manipulation of the connection points 61-68 located between the conductor track structures 51, 52 and 53, 54 is at least significantly more difficult.

Alternatively, the connection points 61-68 on the material strips can also be folded outwards, as shown in Figures 36 and 37. Thus, for example, only the central fold line F3 is used to get to the folded label 1 according to this embodiment. The respective material strips form a relatively rigid contact strip, for the installation or use of which additional reinforcement elements can be dispensed with. Thus, after folding and gluing, a rigidity can be achieved that can be sufficient for a variety of applications for the purpose of contacting.

The illustrated fold lines are therefore not necessarily introduced into the material web of the label 1, 10 as predetermined structures, for example in the form of fold lines, but can merely be intended as intended positions for folding. The fold lines F can be used for folding in both directions, provided the label 10 allows it. However, in order to form a desired folded label 1, it is not necessary to use all existing or possible fold lines (see also Figures 34-37). The four conductor track structures 51-54 according to Figures 30-37 form four separate conductor track loops that are not electrically connected to one another before and after folding. Alternatively, two or more conductor track structures 51-54 can be designed such that they are already electrically connected to one another before or after folding. The connection points 61-68 form eight contact areas for later connections to forwarding lines or conductor tracks 92 to one or more electronic components, such as a chip or a sensor. The connection points 61-68 set up, for example, connection contacts for a power supply or for an electrical connection to a drilling protection film and can be designed relatively thin as flat elements.

The label 1, 10 with four separate conductor track structures 51-54 and eight connection points 61-68 according to Figures 30-37 enables the design of a particularly secure drilling protection film, particularly with regard to a cash card reader or payment terminal. The number of conductor track structures 51-54 and connection points 61-68 are adapted to current security requirements for electronic devices, such as payment terminals, but can alternatively differ or, if such security requirements change, can also be adapted accordingly. Accordingly, two, three, five or more conductor track structures can alternatively be provided, each of which can have one, two or more connection points. Alternatively or additionally, the central third label section 13 according to Figures 30-37 can alternatively also comprise only one, two, three, five or more material strips, with more or wider material strips contributing to a greater stability of the label 1, 10. Alternatively, the central third label section 13 can also be formed over the entire surface or according to the dimensions of the two adjacent label sections 11, 12.

The label 1, 10 according to Figures 30-37 enables, among other things, the following installation situations in a payment terminal with connections to a security chip as an electronic component external to the label 1, 10:

Internal fastening - the third label section 13 with the four material strips and the eight connection points 61-68 located thereon is folded inwards (see Figures 34 and 35); a contact element, for example in the form of a foil or paper element, can have the supply lines 92 and in the area of the third Label section 13 can be inserted, for example glued, between the conductor track structures 51, 52 and 53, 54. Such a film element preferably offers contact points on the top and/or bottom for the respective connection points 61-68. External fastening - the third label section 13 with the four material strips and the eight connection points 61-68 located thereon is folded outwards and connected, for example, to a clamping contact strip (see Figures 36 and 37). The third label section 13 accordingly has a stiffening due to the double material thickness of the material track of the label 1, 10, which can be useful for establishing an electrical connection at the connection points 61-68.
