Abstract

A system, in accordance with one embodiment, comprising a host device including a display, the host device running a client application; and a token device coupled to the host device through an interface, the token device including a processor for running a token device application, the token device application providing image information over the interface to the client application running on the host device, the client application displaying an image on the display of the host device corresponding to the image information provided from the token device.

Claims

1. A token device comprising:

a memory;

an interface for coupling the token device to a host device; and

a processor coupled to the memory, the processor running a token device application stored in the memory of the token device, the processor providing image information to the host device over the interface, the image information for rendering an image corresponding to the application, said image information being transmitted to a client application for rendering on a display of the host device.

2. The token device of claim 1 wherein the client application accepts an input from the host device, wherein the input is routed to the token device.

3. The token device of claim 1 further comprising a read only portion of the memory.

4. The token device of claim 3 wherein the read only portion of the memory stores the client application.

5. The token device of claim 1 further comprising a read and write portion of the memory.

6. The token device of claim 1 wherein the processor is a secure processor.

7. The token device of claim 1 wherein the token device application is a banking application, a point of sale application, a word processing application or a file viewing application.

8. A system comprising:

a host device including a display, the host device running a client application; and

a token device coupled to the host device through an interface, the token device including a processor for running a token device application, the token device application providing image information over the interface to the client application running on the host device, the client application displaying an image on the display of the host device corresponding to the image information provided from the token device.

9. The system of claim 8 further comprising a banking server coupled to the host device through a network.

10. The system of claim 8 further comprising a financial transaction back end coupled to the host device through a network.

11. The system of claim 10 wherein the host device is a transaction terminal.

12. The system of claim 11 where the token device is a smart card.

13. The system of claim 8 further comprising an input device coupled to the host device, wherein the client application accepts an input from the input device of the host device, wherein the input is routed to the token device and interpreted by the token device application.

14. A method of operating a token device comprising:

coupling the token device to a host device through an interface;

running a token device application on the token device;

generating image information; and

sending the image information to the host device through the interface, the image information being rendered by a client application running on the host device.

15. The method of claim 14 further comprising:

publishing a drive on the token device to the host device; and

storing the client application on the drive for download to the host device.

16. The method of claim 14 further comprising sending a message to a bank server through the host device, wherein the token device application comprises a banking application.

17. The method of claim 16 wherein the message to the bank server is encrypted.

18. The method of claim 14 further comprising sending a message to a financial transaction back end through the host device, wherein the token device application comprises a financial transaction application.

19. The method of claim 14 further comprising receiving input information from the host device corresponding to an input received at the host device.

20. The method of claim 19 further comprising providing the input information to the token device application running on the token device.
