Abstract

An element which can be plugged into an EDP device, having a card which is equipped with components, including a processor and data memory, a frame having an exterior form, which is designed to accommodate the card, a first interface for transferring data between the element and the EDP device, and a second interface formed by contacts on the card and on the frame, for transferring data to and from the card. The exterior form of the frame is that of a diskette so that it can be inserted into a diskette station of an EDP device. The first interface between the element and the EDP device is designed in a standard fashion, so that data can be transferred using a standard read/write device already present in the diskette station of the EDP device. The frame carries a battery for supplying current via the interface to the components located on the card, and carries an additional processor and data memory for providing the element with additional processor and storage capacity.

Claims

1. An element which can be plugged into an EDP device, comprising:

a card which is equipped with components, including a processor and data memory;

a frame, having an exterior form, which is designed to accommodate said card;

a first interface for transferring data between the element and the EDP device; and

a second interface formed by contacts on the card and on the frame, for transferring data to and from the card;

the exterior form of said frame being that of a diskette so that it can be inserted into a diskette station of an EDP device,

said first interface between the element and the EDP device being designed in a standard fashion, so that data can be transferred using a standard read/write device already present in the diskette station of the EDP device;

said frame carrying a battery for supplying current via the second interface to the components located on the card, and carrying an additional processor and data memory for providing the element with additional processor and storage capacity via a data link established by the second interface.

2. The element according to claim 1, wherein said frame has a recess for accommodating the drive of the diskette station.

3. The element according to claim 1, wherein the first interface is part of the chip card.

4. The element according to claim 1, wherein said frame is equipped with a current generator.

5. The element according to claim 4, wherein the current generator comprises a rotor which is driven by a drive of the diskette station when the element is inserted therein, a stator and a regulator.

6. A patient data card comprising an element according to claim 1, wherein patient data is stored thereon.

7. A process for access protection comprising utilizing a plurality of elements according to claim 1, wherein access to the data memory is not permitted until a valid access code has been entered.

8. A process according to claim 7, further comprising modifying the access code, wherein modification of the access code is permitted only if the previously valid access code has been input.

9. The element according to claim 1, wherein said card has a recess for accommodating the drive of the diskette station.

10. The element according to claim 1, wherein said frame and said card have a respective recess for accommodating the drive of the diskette station.

11. The element according to claim 1, wherein the frame is equipped with guide rails which accommodate said card.

12. The element according to claim 1, wherein the frame includes a slot into which said card is inserted.

13. The element according to claim 1, wherein the frame includes a recessed grip for facilitating insertion and removal of said card to and from the frame.
