Abstract

In general, embodiments of the present invention provide a card (e.g., identification, debit card, credit card, smart card, etc.) having a dynamic information display panel integrated therein. The display panel is typically activated when user uses the card. This can occur when the card is swiped, and/or is powered up via an integrated energy panel (e.g., by an external light source). Alternatively, the card can be powered by RFID coupling, smart IC contact, battery, etc. Upon powering up, displayed information is used to: identify the user; and/or show private information to user only. Along these lines, displayed information can remain in card memory and/or on the display until next transaction, or it can be deleted after a programmed duration.

Claims

1. A card for dynamically displaying information pursuant to user authentication, comprising:

a dynamic display for displaying information; and

an integrated circuit (IC) for controlling the dynamic display and for accessing a memory medium on the card, the memory medium storing the information.

2. The card of claim 1, the dynamic display comprising a column-row array of pixels.

3. The card of claim 2, the dynamic display further comprising at least one decoder coupled to the column-row matrix of pixels.

4. The card of claim 3, the at least one decoder comprising an analog de-multiplexer.

5. The card of claim 2, the column-row array of pixels comprising a set of transistors.

6. The card of claim 1, the IC comprising:

a central processing unit (CPU);

a display input/output (I/O) coupled to the CPU;

a smart IC I/O coupled to the CPU; and

an RFID I/O coupled to the CPU.

7. The card of claim 6, the memory medium being integrated within the IC.

8. The card of claim 7, the memory medium comprising at least one of the following:

random access memory (RAM), read only memory (ROM), or flash memory.

9. The card of claim 6, further comprising:

a smart IC contact coupled to the smart IC I/O; and

an antenna coupled to the RFID I/O.

10. The card of claim 1, the card and the dynamic display being powered by at least one of the following:

an external power source, a capacitor battery, radio frequency coupling, a radio frequency coupling through RFID, or a smart IC contact.

11. A method for automated card information exchange pursuant to user authentication, comprising:

activating and powering up a card used to complete the user authentication;

performing the user authentication by processing information obtained from the card;

displaying processed information pursuant to the authorizing on a dynamic display integrated on the card; and

determining whether the processed information is valid as displayed on the dynamic display.

12. The method of claim 11, further comprising requesting additional information pursuant to the processed information not being valid.

13. The method of claim 11, the card comprising:

a dynamic display for displaying information; and

an integrated circuit (IC) for controlling the dynamic display and for accessing a memory medium on the card, the memory medium storing the information.

14. The method of claim 11, the dynamic display comprising a column-row array of pixels.

15. The method of claim 14, the dynamic display further comprising at least one decoder coupled to the column-row matrix of pixels.

16. The method of claim 15, the at least one decoder comprising an analog de-multiplexer.

17. The method of claim 14, the column-row array of pixels comprising a set of transistors.

18. The method of claim 13, the IC comprising:

a central processing unit (CPU);

a display input/output (I/O) coupled to the CPU;

a smart IC I/O coupled to the CPU; and

an RFID I/O coupled to the CPU.

19. A method for automated card information exchange pursuant to user authentication, comprising:

activating a card used to complete the user authentication;

performing the user authentication by processing information obtained from the card;

displaying a user identification question on a dynamic display integrated on the card;

processing an answer to the question;

performing an additional authentication based on the answer; and

determining whether the additional authentication is valid.

20. The method of claim 19, further comprising requesting additional information pursuant to the additional authentication not being valid.
