Definitions
- the invention relates to a mechanically activatable transponder device having a transponder coil with at least one contact surface and with a chip element. Furthermore, the invention relates to a chip card with such a transponder device.
- Such a transponder device configured as a contactless chip card is described, for example, in EP 0946926 B1.
- a recess is provided in the chip card whose upper side is closed by a chip module or the chip module is inserted into this recess.
- Within the chip module of the actually integrated circuit is arranged, which is electrically connected to the pads of the chip module.
- the chip module as a whole forms a larger, usually molded unit, which deaerates a manual operation and contacting. Only when pressure on the card is an electrical contact and only then does the smart card work. This is particularly useful for RFID cards, otherwise there would be a danger to the user that he is continuously queried and thus unintentionally detected and monitored.
- the invention has for its object to provide a transponder device of the type mentioned, which is particularly reliable to use.
- the transponder device has a mechanically movable switching membrane which can assume at least two states that the switching membrane positioned over the at least one contact surface of the transponder coil and the Chip element has at least one contact surface, connected to the switching membrane and the at least one contact surface of the transponder coil facing and spaced apart and arranged such that upon movement of the switching membrane, the at least one contact surface of the chip element with the at least one contact surface of the transponder coil is contacted ,
- the transponder coil has two contact surfaces and the chip element also has two corresponding contact surfaces.
- the data stored on the chip element can be read out and transmitted in a contactless manner to a receiver with the aid of the transponder coil.
- the chip element and the transponder coil are provided with opposing contact surfaces which are spaced apart and are only temporarily electrically interconnectable by arbitrary mechanical pressure. Only then will an identification or transaction be triggered. As a result, the user himself determines when the data stored on the chip element can be queried or read out.
- the chip itself is arranged directly in the transponder device as a chip element. It is therefore the "bare", untimed chip or integrated circuit used without forming this in an intermediate step to a module with larger pads.
- the chip is arranged in the chip card according to the invention with downwardly directed contact surfaces in the chip card.
- the chip is arranged in flip-chip technology.
- the contacts of the chip itself are thus turned down and arranged opposite to the contact surfaces of the transponder coil and spaced therefrom.
- the contact surfaces of the chip are preferably formed by the bumps of the chip.
- the contact surfaces of the chip are preferably formed as raised contact pads formed over the chip surface. This is preferably produced by electroless, vacuum-technical or galvanic deposition predominantly of palladium.
- a recess is formed within the chip card between two outer cover sheets.
- the chip is conveniently located in the recess.
- the chip is therefore not directly accessible from the outside, but is at least shielded and protected by a cover sheet and possibly other films or layers of direct contact with the outside world.
- the chip is preferably fastened to one side, in particular of the side opposite the contact surfaces, on the cover film or an underlying further film or layer. This can be done by applying pressure attached chip in the recess moves down and moved to the opposite contact surfaces of the transponder coil.
- the region of the recess ie in particular the interior of the switching membrane with the chip element, in particular the bare chip itself, preferably has an inert atmosphere within the transponder device. This prevents corrosion and ensures the long-term reliability of the transponder device.
- the chip element is preferably fastened to the switch membrane with one side, in particular of the side opposite the contact surfaces, in particular adhesively bonded thereto.
- a gel or gelatinous adhesive is used, which allows a certain flexibility, but after completion of a z. B. lateral pressure, the chip or the chip element pulls back to the desired defined position.
- the switching membrane is preferably formed dome-like.
- the shape of the switching diaphragm is preferably formed as a flattened ball cap, which allows a pressure application or a deflection of this ball cap and thereby can assume two states. This ensures that no accidental or unintentional contact between the chip and the transponder coil or between the contact surfaces arises, but that the application of a mechanical pressure against the spring force is necessary to make such a contact.
- a spring or spring element arranged directly between the contact surfaces and the chip is also conceivable.
- the switching membrane is fastened with its end regions on two spacers arranged on both sides of the chip element.
- the switching diaphragm is preferably designed as a snap-action disc or "crack-frog."
- the upper part of the snap-in disc is freely accessible to the operator, who can therefore actuate the snap-action disc and move the chip attached to the underside of the snap-action disc into the lower contact position via the snap-action disc.
- the covering film covering the recess is comparatively thick, in particular thicker or stronger than the cover film, which is arranged on the side of the chip card opposite the recess.
- the cover sheet covering the recess is more than twice as thick as the opposite cover sheet.
- the thickness of this cover sheet is about 10% or even slightly more than the thickness of the entire chip card.
- the recess is formed within the smart card from two areas, namely an upper and a lower area.
- the lower area is smaller than the upper area.
- the lower portion is dimensioned to be slightly larger than the chip which can be pushed into this lower portion of the recess.
- the upper region is preferably at least twice as wide in width as the chip, so that sufficient possibilities of movement are provided in the region of the overlying cover film.
- Both the upper and the lower region of the recess are each higher in height than the chip. The remaining space within the recess is therefore at least twice as high as the height of the chip.
- the contact surfaces of the transponder coil are made of an interrupted, conductive contact region. This means that particularly preferably at least two contact surfaces of the transponder coil are provided and these are separated from each other by an interruption or a non-conducting region arranged between them. By applying at least two contact surfaces of the chip, this gap is bridged and there is a contact within the chip is thereby supplied with energy through the transponder coil. Alternatively, a connection already exist and only one new contact can be formed when pressure is applied.
- the transponder device has a mechanically movable switching membrane which can assume at least two states, wherein the switching membrane is positioned over the at least one contact surface of the transponder coil and the chip element has at least one contact surface and connected to the switching membrane and facing the at least one contact surface of the transponder coil opposite and spaced therefrom is movably arranged such that upon movement of the switching membrane, the at least one contact surface of the chip element with the contact surface of the transponder coil is contacted.
- This chip card preferably has the embodiments which have also been described above in connection with the transponder device.
- the chip card and the transponder device are preferably an RFID card or RFID transponder device.
- FIG. 1 shows a schematic cross section through a contactless chip card according to the invention
- FIG. 2 shows a cross section according to FIG. 1 with actuated spring element
- Fig. 3 is a partially cutaway plan view of a smart card
- Fig. 5 is a plan view of a chip card with a recess with prepared connections.
- Fig. 1 a cross-sectional view of the chip card according to the invention is initially shown, wherein the spring element is not actuated.
- the chip card is made up of a plurality of layers or layers. The outermost layers are each formed by a cover sheet 1 or 8. Below these cover sheets 1, 8 printed films 2 and 7 are arranged, which give the smart card 20 its actual appearance. Under these films or further to the interior of these films 2 and 7 more films 3 and 6 are arranged. Centrally in the inner area core foils 4 and 5 are arranged. In some smart cards, only a single central core foil is arranged. Between the films 5 and 6, a transponder coil 17 is inserted. The transponder coil 17 is connected to contact surfaces 15 of the transponder coil 17.
- contact surfaces 15 are electrically isolated from each other by an interruption 16 or isolated.
- the chip card 20 has been introduced through the layers of printing film 2, 3 foil and core foils 4 and 5 extending recess 11.
- the layers 1 to 5 which are again continuous behind the recess 11 have not been shown for the sake of clarity.
- spacers 9 are used, whose height extends approximately over the height of the two core sheets 4 and 5 and reduce the recess 11 to dimensions in this area or define the size of the recess 11 in this area approximately such that this is slightly larger than the inserted chip 12 used in the chip card 20, which is used here as a "bare" chip and not as a chip module, the contact surfaces 15 forming the lower end of this lower part of the recess 11.
- Spacers 10 are spacers 10 arranged for this purpose, which are significantly smaller in size than the spacers 9.
- the spacers 10 extend in the height above the height of the film 3 and the printing film 2.
- the height of this upper portion of the recess 11 is slightly larger than the height of the chip 12.
- the chip 12 is arranged in the recess so that its contact surfaces 14 are aligned downward and spaced without mechanical pressure and opposite to the contact surfaces 15 of the Prepared structure of the spacer 10 a spring element 13 inserted or is inserted there.
- This spring element 13 is preferably designed as a snap-action disc or "crackpot frog.”
- the chip is fastened to the underside of the snap-action disc, in particular adhesively bonded with a gel-like adhesive and elastically suspended in this way
- the snap-action disk is dome-shaped and the recess 11 is favorably at least twice as wide in the upper area as the chip 12, so that a sufficient area is provided in which the cover film 1 can give in order to bridge the distance between the contact surfaces 14 of the chip 12 and the contact surfaces 15 of the transponder coil 17.
- the cover film 1 is made particularly thick to ensure sufficient safety and in particular about twice as thick or still thicker than usual un d and the opposite cover sheet. 8
- Fig. 2 shows in the same way a cross section through the chip card according to the invention as Fig. 1.
- the same elements are identified by the same reference numerals.
- FIG. 1 it is shown here how a pressure is exerted on the spring element 13 and the snap disk bends downwards.
- the attached to the snap-action disc chip 12 is thereby inserted into the lower part of the recess 11 and the contact surfaces 14 of the chip 12 contact the contact surfaces 15 at the bottom of the recess.
- FIG. 3 shows a plan view of the chip card 20 according to the invention. Since the upper layers are not shown here, the conductor 17 of the antenna can be seen. In the present embodiment is a high frequency antenna for a frequency of 13.5 MHz. Alternatively, UHF antennas for frequencies of 800 to 900 MHz may be provided. In principle, the antenna structure can be in the form of a closed antenna structure, as a dipole antenna structure, as a slot antenna structure or be formed electrically conductive plastics, colors or particles. In addition to the antenna 17, the opening 19 can be seen here in the chip card, in which the spacers, the spring element and the chip are used. In the lower area, the connection structures can be seen.
- FIG. 4 once again shows a plan view of the chip card 20.
