Abstract

A payment card comprises a store of issuer-defined pre-generated cryptograms that are loaded only once into the Card by a perso-bureau or issuer. An on-board and autonomous electronic display of the personal account number (PAN), card verification value (CVV), or expiration date (EXP) is auto-sequenced through the stored cryptograms. Each value displayed to the user is unique, and useful in a financial transaction only once. The Card thus requires no changes in behavior on the part of the User, because the existing merchant infrastructure is already equipped to collect PAN+CVV+EXP data for user verification and transaction authorization.

Claims

1. A payment card, comprising:

a plastic carrier with the dimensions of a credit card;

a table memory disposed within the plastic carrier and able to be permanently written once during card personalization with an ordered series of cryptograms;

an auto-sequencer disposed within the plastic carrier and connected to the table memory, and providing for an ordered selection of an individual cryptogram that was previously written during said card personalization; and

an electronic display disposed within the plastic carrier able to visually display to a user a personal account number (PAN), a card verification value (CVV), and/or an expiration date (EXP) derived from said individual cryptogram selected by the auto-sequencer.

2. The payment card of claim 1, further comprising:

a one time password device used in conjunction with at least one of the PAN, CVV, and EXP, in the electronic display.

3. The payment card of claim 1, further comprising:

a magnetic stripe disposed on the plastic carrier and providing for a magnetic recording of a virtual account number (VAN) derived from said PAN, CVV, and/or EXP, wherein said VAN is useful in a financial transaction with a merchant; and

a magnetic device disposed within the magnetic stripe and providing for at least some part of said VAN to be internally updated in said magnetic recording without assistance from an external device;

wherein, each new VAN belongs to a sequence of numbers that can be predicted and used to authenticate a transaction instigated through an external legacy card reader.

4. The payment card of claim 1, further comprising:

a virtual account number (VAN) derived from said PAN, CVV, and/or EXP, that is continuously visible on the display long enough to enable a payment transaction which was not instigated by an external legacy card reader.

5. The payment card of claim 1, further comprising:

a 3CVV display included in the electronic display, and for continuously showing current and changing CVV values; and

a pair of permanent and unchanging PAN and EXP values human readable by embossing or printing.

6. The payment card of claim 1, further comprising:

a 4DBC display included in the electronic display, and for continuously showing current and changing 4DBC values; and

a pair of permanent and unchanging PAN and CVV values readable by embossing or printing.

7. The payment card of claim 1, further comprising:

a partial-PAN display included in the electronic display, and for continuously showing the current and changing portions of the PAN; and

a permanent and unchanging remainder of the PAN and the CVV values are embossed or printed on the plastic carrier.

8. The payment card of claim 1, further comprising:

a full-PAN display included in the electronic display, and for continuously showing the current and changing PAN value; and

a pair of permanent and unchanging CVV and EXP values are embossed or printed on the plastic carrier.

9. The payment card of claim 1, further comprising:

a radio transmitter for forwarding at least one of the PAN, CVV, and EXP values to a personal trusted device for display that will enable a financial transaction with a merchant.

12. The financial transaction system of claim 9, further comprising:

a personalization process for permanently recording said tables of cryptograms to a population of said payment cards;

wherein, only said table of cryptograms and not said algorithms and seeds are accessible to a personalization bureau outside a card issuer.

10. A payment card, comprising:

a plastic carrier;

a table memory disposed within the plastic carrier and able to be permanently written once during card personalization with an ordered series of cryptograms;

an auto-sequencer disposed within the plastic carrier and connected to the table memory, and providing for an ordered selection of an individual cryptogram that was previously written during said card personalization; and

a radio transmitter for forwarding at least one of the PAN, CVV, and EXP values to a personal trusted device with an electronic display able to provide a user with a personal account number (PAN), a card verification value (CVV), and/or an expiration date (EXP) derived from said individual cryptogram selected by the auto-sequencer.

11. A financial transaction system, comprising:

a first cryptoprocessor for using an algorithm to generate a table of cryptograms from a seed that are in an ordered series and that are unique and downloaded only once during personalization to a particular payment card;

a second cryptoprocessor for using said algorithm to produce a replicate table of cryptograms from said seed that will also be in said ordered series and that can be predicted to be visually displayed by said particular payment card in subsequent financial transactions;

a validation process for receiving a personal account number (PAN), a card verification value (CVV), and/or an expiration date (EXP) derived from individual cryptograms selected by an auto-sequencer and continuously displayed on said payment cards to a user; and

a transaction decision process for approving or declining a financial transaction involving said payment card according to the validity of the PAN+CVV+EXP values received as determined by said replicate table of cryptograms.
