Abstract

Chip card with which contact is made, comprising a plastic carrier and a programmable microchip, which is fixedly connected to a contacting device for the supply of power and the exchange of data, there being present in the chip card a converter which converts the information picked up, for example inductively, by a contactless receiving system into power-supply and data-processing functions in such a way that the microchip (6) can perform its programmed functions via internal connections without making use of the contacting device and, for its part, can output information contactlessly, for example inductively, via the converter by means of a transmission system. <IMAGE>

Description

Derzeit werden Chipkarten fast ausschließlich mit einem Kon­ taktsystem versehen, welches sowohl die Energiezuführung als auch den Datenaustausch zwischen den Schreib-/Lesegeräten und der Chip­ karte gestattet.Currently, smart cards are almost exclusively with a Kon Provide clock system, which both the energy supply and the data exchange between the read / write devices and the chip card allowed.

Um eine sichere Kontaktgabe zu gewährleisten, werden die Kon­ taktflächen meist vergoldet oder zumindest versilbert. Dennoch kann es durch Verschmutzung zu Betriebsstörungen kommen.To ensure safe contact, the Kon tact surfaces mostly gilded or at least silvered. Yet pollution can lead to malfunctions.

Neuerdings werden "kontaktlose" Chipkarten angeboten, welche den Mangel einer unsicheren Kontaktgabe ausschließen. Die kontakt­ losen Karten arbeiten entweder mit induktiver, kapazitiver oder Funkübertragung. Es sind auch Karten mit optischer Koppelung und Übertragung vorgeschlagen worden.Recently, "contactless" chip cards have been offered, which exclude the lack of unsafe contact. The contact loose cards work either with inductive, capacitive or Radio transmission. There are also cards with optical coupling and Transfer has been proposed.

Der zusätzliche Aufwand für solche Übertragungsmittel ist be­ achtlich, es sei denn, man integriert diese direkt in den Mikro­ chip.The additional effort for such transmission means is be careful unless you integrate them directly into the microphone chip.

Die Einführung von kontaktlosen Chipkarten wird dadurch be­ hindert, daß auf vielen Anwendungsgebieten bereits kontaktierte Karten in Gebrauch und die Schreib-/Lesegeräte entsprechend mit Kontakten bestückt sind.The introduction of contactless chip cards will be prevents contacting in many areas of application Cards in use and the read / write devices accordingly Contacts.

Daher ist es erforderlich, kontaktlose Chipkarten zumindest für eine bestimmte Übergangszeit mit Kontakten auszustatten, um auch diese Karten "kompatibel" in bestehenden Schreib- und Lese­ geräten verwenden zu können. Eine solche Kontakteinrichtung be­ deutet einen zusätzlichen Aufwand und damit Mehrkosten und Einführungsprobleme.Therefore, it is necessary to at least have contactless smart cards to provide contacts for a certain transition period in order to these cards are "compatible" in existing read and write  to use devices. Such a contact device be indicates an additional effort and thus additional costs and Introductory problems.

Aufgabe der Erfindung ist es, eine kostengünstige Lösung an­ zugeben, welche einen reibungslosen Übergang von der kontaktbehaf­ teten zur kontaktlosen Karte gestattet. Erfindungsgemäß wird dies dadurch gelöst, daß in der Chipkarte ein Konverter (7) (Umsetzer) vorhanden ist, welcher die von einem kontaktlosen Empfangssystem (4) z. B. induktiv aufgenommenen Informationen in Stromversorgungs- und Datenverarbeitungsfunktionen derart umsetzt, daß über interne Verbindungen der Mikrochip (6) seine programmierten Funktionen ohne Nutzung der Kontakteinrichtung (3) ausüben und seinerseits Informationen über den Konverter (7) mittels eines Sendesystems (9) z. B. induktiv kontaktlos ausgeben kann.The object of the invention is to provide an inexpensive solution which allows a smooth transition from the contact-making to the contactless card. According to the invention this is achieved in that a converter ( 7 ) (converter) is present in the chip card, which is used by a contactless receiving system ( 4 ) z. B. inductively recorded information in power supply and data processing functions in such a way that via internal connections the microchip ( 6 ) perform its programmed functions without using the contact device ( 3 ) and in turn information about the converter ( 7 ) by means of a transmission system ( 9 ) z. B. can output inductively without contact.

Eine erfindungsgemäße Chipkarte gestattet daher wahlweise eine Datenübermittlung entweder über die Kontakteinrichtung oder kontaktlos über die Empfangs- und Sendesysteme.A chip card according to the invention therefore optionally allows a data transfer either via the contact device or contactless via the reception and transmission systems.

Aus Vereinfachungsgründen wird ferner erfindungsgemäß empfoh­ len, sowohl die Funktionen des kontaktierten, programmierbaren Chips, aber auch des Konverters in einem einzigen Chip zu integrieren.For reasons of simplification, the invention also recommends len, both the functions of the contacted, programmable Chips, but also the converter in a single chip integrate.

Der heutige Stand der Feinstrukturierung von Mikrochips er­ laubt solche Maßnahmen und stellt naturgemäß die billigste Mög­ lichkeit dar, eine kompatible, kombinierte Ausführung von kontakt­ losen und kontaktbehafteten Übertragungen zu erreichen.The current state of fine structuring of microchips permits such measures and naturally provides the cheapest option represents a compatible, combined version of contact to achieve loose and contact transfers.

Besonders vorteilhaft ist erfindungsgemäß auch die Integrie­ rung der Sende- und Empfangssysteme, z. B. in Form von induktiven Spulen. Integrity is also particularly advantageous according to the invention tion of the transmission and reception systems, e.g. B. in the form of inductive Do the washing up.  

Ein erfindungsgemäßer Chip kann aber auch durch zusätzliche Sende-/Empfangseinrichtungen zum Datentransfer über größere Ent­ fernungen verbessert werden, wie beispielsweise für Identifizie­ rungskarten, die auf mehrere Meter ansprechbar sein müssen.However, a chip according to the invention can also have additional ones Sending / receiving devices for data transfer over larger Ent distances are improved, such as for identification cards that must be accessible over several meters.

Eine derartige zusätzliche Empfangseinrichtung kann erfin­ dungsgemäß auch zur Verbesserung der Stromversorgung des Mikro­ chips dienen.Such an additional receiving device can be invented accordingly also to improve the power supply of the micro serve chips.

Die Fig. 1 und 2 zeigen schematisch eine erfindungsgemäße Chipkarte, welche sich rein äußerlich in keiner Art von den bisher üblichen Chipkarten unterscheidet. In Fig. 1 ist lediglich die zu­ sätzlich integrierte Sende-/Empfangseinrichtung (4) angedeutet, welche für die kontaktlose Stromversorgung und Datenübertragung erforderlich ist. Zum besseren Verständnis ist der Kunststoffträ­ ger (1) durchsichtig dargestellt, so daß man auch in Fig. 1 die Kontakteinrichtung (3) erkennen kann, obwohl sie sich auf der rückwärtigen Fläche befindet. Figs. 1 and 2 schematically show a chip card according to the invention, which purely externally differs in no way from the hitherto conventional smart cards. In Fig. 1, only the additionally integrated transmitting / receiving device ( 4 ) is indicated, which is required for the contactless power supply and data transmission. For a better understanding, the plastic carrier ( 1 ) is shown in a transparent manner, so that the contact device ( 3 ) can also be seen in FIG. 1, although it is on the rear surface.

Fig. 2 zeigt die Rückansicht der Chipkarte, ebenfalls mit der schematisch dargestellten Kontakteinrichtung (3). Fig. 2 shows the rear view of the chip card, also with the schematically shown contact device ( 3 ).

In Fig. 3 schließlich ist schematisch die Anordnung einer zu­ sätzlichen Sende- und Empfangseinrichtung, beispielsweise als In­ duktionsspule (5), dargestellt.In Fig. 3, finally, the arrangement of an additional transmitting and receiving device, for example as an induction coil ( 5 ), is shown schematically.

Schon rein äußerlich läßt sich erkennen, daß bei einer sol­ chen Ausführung die Umstellung von einer kontaktierten Karte auf eine kontaktlose Karte problemlos vonstatten gehen kann. Es sind keinerlei zusätzliche Kosten, verglichen mit einer bisher üblichen kontaktbehafteten Karte, erforderlich. Es können die gleichen Fertigungseinrichtungen, die bereits für Massenproduktionen vor­ handen sind, benützt werden, und im späteren Verlauf ist die Um­ stellung auf eine rein kontaktlose Ausführung einfach durch Weglassen der Kontakteinrichtung möglich, was eine beträchtliche Kostenreduktion darstellt durch Einsparung der vergoldeten Kon­ takte. Already externally it can be seen that with a sol Chen execution the switch from a contacted card to a contactless card can be issued without any problems. There are no additional costs compared to a previously usual contact card, required. It can be the same Manufacturing facilities already in place for mass production are available, are used, and in the later course the order is simply switch to a purely contactless version Omission of the contact device possible, which is considerable Cost reduction represents by saving the gold-plated con clock.  

Fig. 4 zeigt schematisch die Erweiterung eines kontaktierten Mikrochips (6), welcher mit seiner Kontakteinrichtung (3) alle programmierten Funktionen zur Datenein- und -ausgabe ausführt. Fig. 4 shows schematically the expansion of a contacted microchip ( 6 ), which performs all programmed functions for data input and output with its contact device ( 3 ).

Zur dualen Funktion ist ein Konverter (Umsetzer) (7) erfor­ derlich, welcher die von der Induktionsspule (4) aufgenommenen Informationen verarbeitet und über innere Verbindungen (8) dem programmierbaren Mikrochip (6) zuführt. Ebenso können über eine zweite Spule (9), die als Sendeeinrichtung arbeitet, Daten ausge­ geben werden. Alle diese Bauteile sind zu einem Mikrochip (2) zu­ sammengefaßt, welcher in der Lage ist, dual entweder über die Kon­ takteinrichtung (3) oder über die Induktionsspule (4) kontaktlos betrieben zu werden.For the dual function, a converter (converter) ( 7 ) is required, which processes the information recorded by the induction coil ( 4 ) and feeds it to the programmable microchip ( 6 ) via internal connections ( 8 ). Likewise, data can be output via a second coil ( 9 ), which works as a transmitting device. All of these components are combined to form a microchip ( 2 ) which is capable of being operated contactlessly either via the contact device ( 3 ) or the induction coil ( 4 ).

Eine weitere Vereinfachung besteht darin, anstelle von zwei Spulen (4) und (9) nur eine Spule für beide Funktionen vorzusehen. Auch die erforderliche Stromversorgung kann über die Empfangsein­ richtung vorgenommen werden.A further simplification is to provide only one coil for both functions instead of two coils ( 4 ) and ( 9 ). The required power supply can also be carried out via the receiver.

Kontaktierte Chipkarten sind bereits weitgehend genormt, so daß die erfindungsgemäße Ausführung kontaktloser Karten helfen würde, diese Technologien auf breiter Basis schnell einführen zu können.Contacted chip cards are already largely standardized, so that the inventive design of contactless cards help would quickly implement these technologies on a broad basis can.

Die schematischen Darstellungen sind nur zum besseren Ver­ ständnis gezeigt und haben keinerlei einschränkende Bedeutung. Es können sowohl verschiedene Sende- /Empfangssysteme nebeneinander, aber auch verschiedenartige Übertragungsarten verwendet werden, z. B. Amplituden- und Frequenzmodulation oder ähnliche Verfahren.The schematic representations are only for better ver shown and have no restrictive meaning. It different transmission / reception systems can be placed side by side, but also different types of transmission are used, e.g. B. amplitude and frequency modulation or similar methods.

Die Erfindung ist sowohl für einfache Speicherkarten, aber auch für komplexe Mikroprozessorkarten anwendbar, unabhängig von der bevorzugten Art der Datenübertragung.The invention is for simple memory cards, however also applicable for complex microprocessor cards, regardless of the preferred type of data transmission.
