Abstract

Communications system having a chip card and at least one chip card communications partner, the chip card having a module for initiating data interchange with the chip card communications partner, and a method for interchanging data between a chip card and a chip card communications partner, the chip card initiating data interchange.

Claims

1. A communications system comprising a chip card and a chip card communications partner, wherein the chip card has a module for initiating data interchange with the chip card communications partner.

2. The communications system of claim 1, wherein the chip card has a standard interface.

3. The communications system of claim 2, wherein the chip card has a plurality of standard interfaces.

4. The communications system of claim 1, further comprising a plurality of chip card communications partners, wherein the chip card module initiates data interchange with the plurality of chip card communications partners.

5. The communications system of claim 2, comprising an additional line, which is not part of the standard interface, and is for transmitting an initiation signal.

6. The communications system of claim 2, wherein the standard interface corresponds to the ISO-7816 standard.

7. A method for interchanging data between a chip card and a chip card communications partner, wherein the chip card initiates data interchange.

8. The method of claim 7, wherein the data interchange is initiated by signaling using a standard interface.

9. The method of claim 8, wherein the data interchange is initiated by signaling using a plurality of standard interfaces.

10. The method of claim 7, wherein the chip card initiates the data interchange with a plurality of chip card communications partners.

11. The method of claim 7, wherein the data are interchanged via a first interface, and the initiation is effected via a second interface.

12. The method of claim 8, wherein the standard interface corresponds to the ISO-7816 standard.

13. A communications system comprising a chip card and a chip card communications partner, wherein the chip card has a means for initiating data interchange with the chip card communications partner.
