Abstract

The card design prevents loss of data that is possible when the external source is not supplying current to the volatile components. It has a flat lithium battery incorporated in the body of the card. The thickness of the battery does not exceed 0.3 mm. in thickness. When the external source is switched off, the internal logic switches the processor into standby working. It switches the supply to the battery by means of a condenser acting as an energy buffer or store. Alternatively, solar cells, thermoelements or field utilisation can be employed.

Description

Die Erfindung betrifft eine Chipkarte, wie sie grund­ sätzlich aus vielen und sich ständig erweiternden Anwendungen bekannt ist, z. B. als Kreditkarte, Sparkassen- und EC-Karte, Zeiterfassungskarte sowie Zutrittskontroll- und Tankkarte. Ihr Einsatz bietet sich besonders dann an, wenn Daten in jedem Fall sicher im volatilen Speicher abgelegt werden sollen.The invention relates to a chip card, as is basic additionally from many and constantly expanding Applications are known, e.g. B. as a credit card, Sparkasse and EC card, time registration card and Access control and fuel card. Your commitment is offered especially when data is always secure in the volatile memory should be stored.

Derzeit besteht bei Chipkarten beim Abschalten der externen Versorgungsspannung keine Möglichkeit, Daten im volatilen Speicher zu deponieren. Andererseits können aus Performancegründen die Daten nicht immer in non-volatile Speicher (z. B. E²PROM) abgelegt werden, da die Schreib­ zugriffe auf diese Medien zu viel Zeit in Anspruch nehmen.Currently there is a chip card when switching off external supply voltage no possibility of data in to deposit volatile storage. On the other hand, can For performance reasons, the data is not always in non-volatile Memory (e.g. E²PROM) can be stored because the write Accessing these media takes too much time.

Es ist daher Ziel und Aufgabe der Erfindung, eine Chip­ karte vorzuschlagen, die es ermöglicht, für spezifische Applikationen Daten, die auch beim Abschalten der Versor­ gungsspannung erhalten bleiben müssen, innerhalb der Chipkarte im volatilen Speicher abzulegen.It is therefore the object of the invention, a chip propose a card that allows for specific Applications data, even when the utility is switched off voltage must be maintained within the Store chip card in volatile memory.

Erfindungsgemäß wird dies dadurch gelöst, daß in der Chipkarte eine interne Energiepufferung oder interne Energiegewinnung, die nach dem Abschalten der externen Versorgungsspannung die volatilen Komponenten, z. B. RAM, mit Energie versorgt, implementiert wird.According to the invention this is solved in that in the Chip card an internal energy buffering or internal Energy generation after switching off the external Supply voltage the volatile components, e.g. B. RAM, supplied with energy, is implemented.

Als bevorzugte Realisierung wird eine flache Lithium- Batterie, deren Dicke 0,3 mm nicht überschreitet, in den Kartenkörper eingebrachte. Bei Versorgungsspannungsverlust schaltet eine interne Logik den Prozessor in den Standby- Betrieb sowie die Versorgung an die Batterie, z. B. eine Lithium-Batterie; analog geschieht dies bei Energie­ pufferung mittels eines Kondensators.A flat lithium Battery whose thickness does not exceed 0.3 mm in the  Card body introduced. In case of loss of supply voltage internal logic switches the processor to standby Operation as well as the supply to the battery, e.g. Legs Lithium battery; the same happens with energy buffering by means of a capacitor.

Die interne Energieerzeugung bzw. Energiegewinnung kann aber auch mit allen anderen hierfür bislang technisch eingeführten Methoden, z. B. mittels Solarzellen, Thermoelementen, Feldnutzung usw. realisiert sein.The internal energy production or energy generation can but also technically with all others so far established methods, e.g. B. by means of solar cells, Thermocouples, field use, etc. can be realized.
