Abstract
Description
Die Erfindung betrifft ein Einsteckfach zur Aufbewahrung von Chip-Karten oder dergleichen, wie beispielsweise Personalausweise oder Reisepässe im Chip-Kartenformat oder Karten mit einem RIFD/RFID-Chip (Radio Frequency Identification) zum Beschreiben und Auslesen von auf der Karte abgespeicherten Daten. Dieser RFID-Standard bezeichnet eine Radiofrequenzidentifikation, die eine Funktechnik zur Datenübertragung zum Inhalt hat. Betroffene Frequenzbereiche reichen derzeit von 125 kHz bis 2,5 GHz.The The invention relates to a pocket for storing chip cards or the like, such as identity cards or passports in chip card format or cards with a RIFD / RFID (Radio Frequency Identification) chip Describe and read data stored on the card. This RFID standard denotes a radio frequency identification, which is a radio technology for data transmission has to content. Affected frequency ranges currently reach from 125 kHz to 2.5 GHz.
Die elektronischen Etiketten nach dem RFID-Standard sorgen bei vielen Beobachtern für Unbehagen. Sie fürchten, dass die über mehrere Meter berührungsfrei lesbaren Produktkennzeichnungen zur Überwachung missbraucht werden könnten. Bislang wird die RFDI-Technik vor allem zur Lagerverwaltung genutzt. Um gemäß dem Stand der Technik einen möglichen Missbrauch zu vermeiden, soll gegenwärtig bei derartigen Chip-Karten für finanzielle Transaktionen letztere nur bei einer direkten Berührung der Chip-Karte mit einem Lesegerät möglich sein. Zu diesem Zweck setzen die Hersteller auf das mit RFID verwandte, aber in der Reichweite deutlich reduziertere Verfahren NFC (Near Field Communications). Doch auch hier ist nicht gewährleistet, dass ein vom Inhaber der Chip-Karte ungewolltes Auslesen/Schreiben der Daten unterbleibt.The Many electronic labels comply with the RFID standard Observers of discomfort. They fear, that over several meters non-contact readable product labels are misused for monitoring could. So far The RFDI technology is mainly used for warehouse management. Around according to the state the technology a possible To avoid abuse, is currently in such chip cards for financial Transactions latter only with a direct touch of the Chip card with a reader to be possible. For this purpose, manufacturers rely on RFID-related, but in the range significantly reduced procedures NFC (Near Field Communications). But even here is not guaranteed that one from the owner of the chip card Unintentional reading / writing of the data is omitted.
Aufgabe der Erfindung ist es damit eine Manipulation oder ein ungewolltes Auslesen von Daten des Kartenchips zu verhindern.task The invention is thus a manipulation or an unwanted Prevent reading data from the card chip.
Diese Aufgabe wird gelöst durch ein Einsteckfach gemäß Anspruch 1. Vorteilhafte Ausführungsformen ergeben sich aus den jeweiligen Unteransprüchen.These Task is solved through a pocket according to claim 1. Advantageous embodiments emerge from the respective subclaims.
Grundgedanke der Erfindung ist, ein Abschirmgewebe im Einsteckfach für eine Chip-Karte oder einen Ausweis in einem solchen Chip-Kartenformat vorzusehen, das eine elektrostatische, magnetostatische oder elektromagnetische Abschirmung umfasst. Damit erreichen von außen abgegebene, beispielsweise mittels eines Transponders abgestrahlte Hochfrequenzwellen nicht mehr den Kartenchip und vice versa, d.h. der Transponder auf der Chip-Karte ist nicht mehr für einen Datenaustausch bereit.basic idea The invention is a shield fabric in the slot for a chip card or a To provide ID card in such a chip card format, the one electrostatic, magnetostatic or electromagnetic shielding includes. With it reach from the outside delivered, for example by means of a transponder radiated high frequency waves no longer the card chip and vice versa, i. the transponder on the chip card is no longer for a data exchange ready.
Gemäß einer vorteilhaften Ausführungsform ummantelt das Abschirmgewebe im Einsteckfach eine in das Einsteckfach eingesteckte Chip-Karte derart vollständig, dass eine Faradaysche Umhüllung für die gesamte Chip-Karte geschaffen ist, bzw. eine elektromagnetische Welle reflektiert wird. Eine faradaysche Abschirmung wird dabei bereits mit einem Drahtmaschennetz realisiert, dessen Drahtmaschen-Größe unterhalb der halben Wellenlänge dimensioniert ist. Die Abschirmung erfolgt gegen induktive Wirkungen sowie gegen bereits in den Wellenlängenbereichen von RIFD/RFID-Karten auftretenden Wirkungen. Ferner kann es vorgesehen sein, ein Abschirmgewebe in mehreren Schichten im Einsteckfach vorzusehen, sodass der Abschirmbereich über einen weiten Frequenzbereich wirkt.According to one coated advantageous embodiment the shielding fabric in the pocket a plugged into the pocket Chip card so completely, that a Faraday wrapper for the entire Chip card is created, or reflected an electromagnetic wave becomes. A Faraday shield is already using a wire mesh net realized whose wire mesh size dimensioned below half the wavelength is. The shielding takes place against inductive effects as well as against already in the wavelength ranges RIFD / RFID Card Effects. Furthermore, it can be provided be to provide a shielding fabric in several layers in the pocket, so that the shielding area over a wide frequency range acts.
Als Abschirm-Gewebe können auch Kunststofffolien mit definiertem Schichtaufbau verwendet werden. So wird für eine vorteilhafte Ausführungsform der Erfindung eine mittelschichtige oder durchgehend homogene Einlage von metallischen, metalloxydischen, sulfidischen, silicidischen, boridischen, nicht toxisch wirksam werdenden arsenidischen und anderen geeigneten Leitfähigkeitsvermittlern vorgeschlagen, die allesamt in der Lage sind, eine faradaysche abschirmende, durchkontaktierende Wirkphase zu realisieren. Dies kann soweit perfektioniert werden, dass innerhalb der Kunststofffolie der schichtenlagige Aufbau einer flexiblen und leitfähigen Keramik vorliegt.When Shielding fabric can Also plastic films are used with a defined layer structure. So will for an advantageous embodiment the invention, a middle-layer or continuous homogeneous insert of metallic, metalloxy, sulphidic, silicidic, boridic, non-toxic arsenidic and others suitable conductivity mediators all of which are capable of shielding a Faraday shield, durchkontaktierende effective phase to realize. This can be perfected so far be that within the plastic film the layered construction a flexible and conductive Ceramic is present.
Als Metallgewebeeinlage sind auch feinmaschige, metallische Siebdruckfolien geeignet, die eine geeignete Maschenzahl von beispielsweise 1000/cm2 aufweisen.As a metal fabric insert and fine mesh metallic screen printing films are suitable, which have a suitable mesh size of, for example, 1000 / cm 2 .
Vorrichtungsgemäß werden auch feinste, für elektromagnetische Abschirmung verwendbare, metallische Gespinste mit Maschen ebenso als Drahtgaze bezeichnet, und deren ein- oder mehrlagige Applikationen als Metallgewebeeinlage bezeichnet und verwendet. Sehr gut ist weich-magnetisches Drahtgaz, wie dies bei den meisten metallischen Nickel-Chrom-Siebdruckgeweben aus Festigkeits- und Korrosionsschutzgründen der Fall ist, da hiermit auch überlagernde, magnetostatische Komponenten zu den eigentlich abzuschirmenden Feldern sicher mitabgeschirmt werden. Die schlechte elektrische Leitfähigkeit der Drahtgaze sichert das ohmsche Totlaufen der primär induzierten Wirbelströme. Zur Dünnschichtmetallisierung eignen sich die ausgereiften Verfahren der Kunstfasernmetallisierung, wie der Ionenplattierung, der Kathodenzerstäubung und des CDV-Verfahrens, die ausgezeichnete Haftungsergebnisse auf einer Grundfaser erbringen.According to the device also finest, for electromagnetic Shielding metallic meshes with mesh as well referred to as wire gauze, and their single or multi-layer applications referred to as metal mesh insert and used. Very good is soft-magnetic Drahtgaz, as is the case with most metallic nickel-chromium screen-printed fabrics for strength and corrosion protection is the case, since herewith also overlaying, Magnetostatic components to the fields actually to be shielded safely mitabgeschirmt be. The bad electrical conductivity The wire gauze ensures the ohmic dead run of the primary induced Eddy currents. For thin-film metallization are the mature methods of synthetic fiber metallization, such as ion plating, sputtering and the CDV process, to provide excellent adhesion results on a base fiber.
Die Erfindung umfasst damit jegliches Abschirmmaterial maschiger metallisierter Gewebe, Vlies oder einer metallisierten Folie, sowie einer abschirmenden Metallplatte, einem Metallgehäuse, etc.The The invention thus encompasses any shielding material of meshed metalized Fabric, non-woven or a metallized film, as well as a shielding Metal plate, a metal case, Etc.
Ein Vorhandensein weichmagnetischer Eigenschaften der metallischen Aufschichtung bewirkt eine Brechung anstehender Feldlinien ins Material hinein und über innere magnetische Verlustarbeit ein Totlaufen derselben. Je höher die Permeabilität des Materials ist, desto besser ist die Abschirmung. Mit der Eigenschaft elektrischer Leitfähigkeit des Abschirm-Gewebes wird gewährleistet, dass die Feldlinien in den Oberflächenladungen auf der Außenseite der metallischen Aufschichtung enden (Skineffekt) und nicht ins Innere des Einsteckfaches gelangen.One Presence of soft magnetic properties of the metallic coating causes a refraction of pending field lines into the material and over internal magnetic loss work a dead run of the same. The higher the permeability the material is, the better the shielding. With the property electrical conductivity the shielding fabric is ensured that the field lines in the surface charges on the outside of the Metallic coating ends (skin effect) and not into the interior get the slot.
Erwartungsgemäß und nach bestätigbaren praktischen Versuchen des Erfinders werden Wellen/Frequenzen gegen unbeabsichtigte/unzulässige Zugriffe auf den Abschirmraum abgeschirmt.As expected and after confirmable practical Attempts of the inventor become waves / frequencies against unintentional / unauthorized accesses shielded on the shielding room.
