Abstract

These and other objects of the invention are accomplished by providing a fingerprint identification credit/debit card system where a bitmap generated from a scan of the user's finger, in combination with a user selected and changeable PIN, is the only data associated with the card. The bitmap, or an electronic representation thereof, is stored on the credit/debit card, as well as in the card issuer computer system. The PIN is stored only on the card issuer computer system. When the user presents the card to a merchant or service provider, the bitmap stored on the card is input using an appropriate input device which may be a magnetic card reader, a scanner, or a device capable of receiving data from an electronic chip, and transmitted to the card issuer computer system for verification and authorization. The user manually inputs the PIN using an associated keypad. If the comparison of the bitmap and PIN presented by the user generates a match with that stored in the card issuer computer, then the user presenting the card is given authorization to use the card for a transaction.

Claims1

Dependent claims

A credit/debit card identification method comprising the steps of:

scanning a cardholder fingerprint into a computer system to generate a bitmap image and storing the bitmap image in a digitized format, as well as a cardholder selected PIN, in a card database of said computer system, encoding said bitmap image on said card for subsequent verification,
presenting said encoded card to a merchant for processing by a card reader and verification by said card database or said server database wherein, said bitmap image on said encoded card is applied to a comparison circuit which is operated by a comparison circuit software program,
applying said bitmap image derived from the merchants card reader to said comparison circuit, if said bitmap image from said card reader is similar to said bitmap image stored on said card database or server database, the card is validated conversely, if the two bitmap images are not identical, the card is invalidated;
allowing a transaction based upon entry and comparison of a PIN to the stored cardholder selected PIN, as well as the merchant's visual inspection of a valid photo identification presented by the cardholder at the time of the transaction.
