Abstract

A system, method and credit card configured to display a current card balance on the credit card. The credit card receives a balance request from a button on the card. After retrieving the current card balance encoded on the credit card, the card displays the current card balance. Remote terminals may be configured to support the real-time display of a balance on a credit card by writing the current balance to the card after a payment transaction has occurred.

Claims

1. A method performed by a credit card comprising:

in a first process of displaying a current card balance, receiving a balance request from a button on the credit card, wherein the credit card is associated with only a single credit card account;

processing the balance request using a processor of the credit card, wherein processing the balance request comprises prompting for input of a personal identification number (PIN);

retrieving the current card balance encoded on a non-volatile programmable memory of the credit card that is configured to store the current card balance;

displaying the current card balance on a display of credit card, wherein the display is coupled to a plastic support imprinted with credit card information;

in a second process of displaying a current remaining credit limit, receiving a current remaining credit limit request from the button on the credit card, wherein the current remaining credit limit equals approximately the difference between a credit limit associated with the credit card account and the current card balance;

processing the current remaining credit limit request using the processor of the credit card, wherein processing the current remaining credit limit request comprises prompting for input of a PIN;

retrieving the current remaining credit limit encoded on the non-volatile programmable memory of the credit card that is configured to store the current remaining credit limit; and

displaying the current remaining credit limit on the display of credit card.

2. The method of claim 1, further comprising:

determining whether the personal identification number is valid.

3. The method of claim 2, wherein the current card balance is displayed only if the personal identification number is determined to be valid.

4. The method of claim 1, wherein the current card balance is encoded on a magnetic stripe on the credit card.

5. The method of claim 4, wherein the current card balance is encoded on track 3 of the magnetic stripe on the credit card.

6. The method of claim 1, wherein the current card balance is encoded on a non-volatile programmable memory in the credit card.

7. The method of claim 1, wherein the credit card performs credit card transactions only.

8. A credit card comprising:

a credit card account associated with the credit card;

a plastic support imprinted with credit card information;

a processor coupled to the plastic support;

a non-volatile programmable memory, coupled to the processor, configured to store a current card balance;

a button configured to receive a request for the current card balance and configured to receive a request for a current remaining credit limit, wherein the current remaining credit limit equals approximately the difference between a credit limit associated with the credit card account and the current card balance; and

a display configured to show, after receiving an input of a personal identification number (PIN) on the credit card responsive to the button receiving the requests, the current card balance when the button receives the request for the current card balance and the current remaining credit limit when the button receives the request for the current remaining credit limit.

9. The credit card of claim 8, further comprising:

a processor configured to determine whether the personal identification number is valid.

10. The credit card of claim 9, wherein the current card balance is displayed only if the personal identification number is determined to be valid.

11. The credit card of claim 8, further comprising a conductive contact making element for interaction with a point of sale device.

12. The credit card of claim 8, further comprising a contactless element for interaction with a point of sale device.

13. The credit card of claim 8, further comprising a numeric or alphanumeric keypad coupled to the processor.

14. The credit card of claim 8, further comprising a plurality of buttons for entering alphanumeric information coupled to the processor.

15. The credit card of claim 14, wherein plurality of buttons for entering alphanumeric information comprise an up arrow button and a down arrow button.

16. The credit card of claim 8, further comprising a numeric or alphanumeric keypad coupled to the processor.

17. The credit card of claim 8 further comprising a button configured to receive a request for a current remaining cash advance limit.

18. The credit card of claim 17, wherein the button configured to receive a request for a current remaining cash advance limit and the button configured to receive a request for the current card balance are different buttons.

19. The credit card of claim 17, wherein the current remaining cash advance limit is determined by subtracting a current cash advance balance from a cash advance limit.

20. The credit card of claim 8, wherein the credit card stores only credit card data.

21. The credit card of claim 20, wherein the credit card does not perform debit card functions.
