Abstract

A novel credit or charging card is disclosed. According to one implementation, the card comprises an e-paper type of display on at least one of two surfaces of the card. An advertising message may be displayed. The advertising message may be replaced by a new one when the card is connected to a card reader. The advertising message may be selected based upon a data file stored in a storage unit of the card. The data file includes a purchase history of the user using the card. According to one embodiment of the invention, the card and the reader are coupled through an optical power transfer module and an optical communication module. Operations of the card are powered by optical energy transmitted from the card reader.

Claims

1. An advertising message delivery system comprising:

a. a card reader and a financial transaction card, wherein the card reader and the card can be coupled through an optical communication module and an optical power transfer module; and

b. an electrically replaceable display on one of two surfaces of the card pertaining to displaying an advertising message transferred from the card reader through the optical communication module,

wherein operations of the card is powered by power transferred from the card reader through the optical power transfer module when the card and the card reader are coupled.

2. The system as recited in claim 1, wherein said optical communication module further comprises:

a. a transmitter and a receiver in the card reader; and

b. a transmitter and a receiver in the card.

3. The system as recited in claim 2, wherein said transmitters further comprise light emitting diodes.

4. The system as recited in claim 2, wherein said receivers further comprise photodiodes.

5. The system as recited in claim 1, wherein said optical power transfer module further comprises:

a. a light source in the card reader; and

b. an optical power receiver in the card.

6. The system as recited in claim 5, wherein said light source further comprises a laser.

7. The system as recited in claim 5, wherein said light source further comprises a light emitting diode.

8. The system as recited in claim 5, wherein said optical power receiver further comprises photodiodes.

9. The system as recited in claim 5, wherein said light source and said optical power receiver are employed to transfer data from the card reader to the card.

10. The system as recited in claim 1, wherein said electrically replaceable display further comprises an e-paper type of display.

11. The system as recited in claim 1, wherein said card further comprises a file storage unit for storing a data file including a purchase history of a user using the card.

12. The system as recited in claim 1, wherein said card further comprises a light-to-electrical power converter and an energy storage unit pertaining to accumulating energy for replacing displayed advertising message on the electrically replaceable display by a new advertising message.

13. An advertising message delivery system comprising:

a. a card reader and a financial transaction card, wherein said card reader and card can be coupled through a communication module and a power transfer module;

b. an electrically replaceable display on one of two surfaces of the card; and

c. a light-to-electrical power converter on one of the two surfaces of the card.

14. The system as recited in claim 13, wherein said card further comprises a processor and a file storage unit pertaining to storing advertising messages transferred from the card reader through the communication module.

15. The system as recited in claim 13, wherein said light-to-electrical power converter further comprises solar cells.

16. The system as recited in claim 13, wherein said power generated from said light-to-power converter is used to replace an advertising message displayed on the electrically replaceable display by a new advertising message, when the card and the card reader are decoupled.

17. The system as recited in claim 13, wherein said electrically replaceable display further comprises an e-paper type of display.

18. The system as recited in claim 13, wherein said card further comprises an energy storage unit and a switch.

19. The system as recited in claim 18, wherein said energy storage unit is a capacitor.

20. The system as recited in claim 18, wherein said energy storage unit stores a sufficient amount of energy for replacing a displayed advertising message on the electrically replaceable display by a new advertising message.
