Abstract

A system comprising a first device and a second device having an electronic data card associated therewith, information on the electronic data card being useable by and accessible by the first device, wherein the first device is arranged to control the operating characteristics of the electronic data card of the second device. Thus the first device may power up/down the electronic data card, reset the electronic data card or change the clock or baud rate associated with the electronic data card.

Claims

1. A system comprising a first device and a second device having an electronic data card associated therewith, information on the electronic data card being useable by and accessible by the first device, wherein the first device is arranged to control the operating characteristics of the electronic data card of the second device.

2. A system according to claim 1 wherein the first device is operable to control the power supply to the electronic data card.

3. A system according to claim 1 or 2 wherein the first device is operable to reset the electronic data card.

4. A system according to claim 1, 2 or 3 wherein the first device is operable to change the clock rate of the electronic data card in the second device.

5. A system according to any preceding claim wherein the first device is operable to change the baud rate of the electronic data card in the second device.

6. A system according to any preceding claim wherein the electronic data card is a Subscriber Identity Module (SIM) card.

7. A system according to any of claims 1 to 6 wherein the electronic data card is a cash card.

8. A system according to any of claims 1 to 6 wherein the electronic data card is a security card.

9. A system according to any preceding claim wherein at least one of the first and second device is a radio telecommunications device.

10. A system according to any preceding claim wherein at least one of the first and second device is a radio telephony device.

11. Apparatus comprising a first device operable with a second device having an electronic data card associated therewith, information on the electronic data card of the second device being useable by and accessible by the first device, wherein the first device is arranged to control the operating characteristics of the electronic data card of the second device.

12. Apparatus comprising a first device having an electronic data card associated therewith, said first device being operable with a second device, information on the electronic data card of the first device being useable by and accessible by the second device, wherein the first device is arranged such that the operating characteristics of the electronic data card of the first device are controlled by the second device.

13. A method of controlling the operation of a first device having an electronic data card associated therewith, information on the electronic data card being useable by and accessible by a second device, wherein the operating characteristics of the electronic data card of the first device are controlled by the second device.
