Patent ID: 8123124

Claim:
A method for financial card anti-fraud security comprising performing, on a processor of a card anti-fraud security system, a first read step to determine a first characteristic fingerprint of the card; generating, on a processor of the card anti-fraud security system, a first set of security data from the first characteristic fingerprint; storing, on the card anti-fraud security system, the first set of security data; and validating the financial card on a processor of the card anti-fraud security system by performing a second read step to determine a second characteristic fingerprint of the card, generating a second set of security data from the second characteristic fingerprint of the card, comparing the second set of security data with the first set of security data, and returning either a valid answer when the second set of security data matches the first set of security data, or an invalid answer when the second set of security data does not match the first set of security data, such that the first characteristic fingerprint and the second characteristic fingerprint both comprise a magnetic stripe fingerprint, or an RFID fingerprint, or intelligent chip fingerprint.
