Claim:
The 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; 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; and 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.
