Abstract

Numerous embodiments of an apparatus and method of a smartcard having a dynamic display portion. In one embodiment, the smartcard includes a dynamic display portion made of an electronic ink, in which the dynamic display portion changes from a first display to a second display in response to an application use of the smartcard.

Claims

1-14. -14. (canceled)

15. A method comprising:

powering a smartcard for use with a plurality of application programs, the smartcard having a dynamic display;

activating a display chooser for the smartcard;

retrieving display data associated with a currently selected one of the applications from electronic storage media to the display chooser; and

changing the dynamic display using the display chooser based on the retrieved display data.

16. The method of claim 15, wherein powering further comprises interfacing the smartcard with a smartcard reader.

17. The method of claim 15, wherein powering further comprises drawing energy through an RFID tag.

18. The method of claim 15, wherein retrieving further comprises providing an electronic ink display controller with the display data.

19. The method of claim 18, wherein changing further comprises charging the electronic ink to generate the first display on the dynamic display.

20. The method of claim 15, wherein retrieving further comprises obtaining display data associated with the currently selected application program from electronic storage media.

21. A method, comprising:

powering an RFID tag disposed on a smartcard hosting a plurality of application programs;

selecting an application program from the plurality of hosted application programs;

retrieving display data associated with the selected application program; and

updating a dynamic display disposed on the smartcard with the retrieved display data.

22. The method of claim 21, wherein powering further comprises drawing energy through the RFID tag.

23. The method of claim 21, wherein retrieving further comprises linking display data with the currently selected application program.

24. The method of claim 23, wherein retrieving further comprises retrieving the display data from electronic storage media.

25. The method of claim 24, wherein updating further comprises forwarding the retrieved display data to a display controller.

26. The method of claim 25, wherein updating further comprises instructing the dynamic display to generate a display based on the display data.

27. The method of claim 21, wherein the dynamic display comprises electronic ink and updating further comprises charging the electronic ink to generate a display on the dynamic display portion.

28. The method of claim 21, wherein retrieving further comprises receiving display data through the RFID tag

29. A smartcard, comprising:

a plurality of application programs;

a dynamic display; and

display controller logic to set the dynamic display responsive to an active one of the application programs.

30. The smartcard of claim 29, wherein the application program is active responsive to an input received by the smartcard.

31. The smartcard of claim 30, wherein the input is received via an RFID tag.

32. The smartcard of claim 29, wherein the dynamic display displays a logo associated with active application program.

33. The smartcard of claim 29, further comprising electronic storage media containing display data corresponding to each application program on the smartcard.

34. The smartcard of claim 29, wherein the dynamic display consists of electronic ink.

35. The smartcard of claim 31, wherein the RFID tag receives display data to change the dynamic display.

36. The smartcard of claim 35, wherein the smartcard receives power to change the dynamic display via the RFID tag.

37. A method, comprising:

hosting a plurality of application programs on a smartcard having a dynamic display;

selecting one of the plurality of application programs; and

changing an image displayed on the dynamic display responsive to the selection of one of the application programs.

38. The method of claim 37, wherein changing the dynamic display further comprises receiving display data associated with the application program.

39. The method of claim 38, wherein receiving the display data further comprises retrieving display data associated with the selected application program from electronic storage media.

40. The method of claim 38, wherein changing the dynamic display further comprises receiving display data via an RFID tag disposed on the smartcard.

41. The method of claim 40, wherein changing the dynamic display further comprises drawing power for the smartcard through the RFID tag.

42. The method of claim 37, wherein changing the dynamic display further comprises charging electronic ink.
