Abstract

A method for providing secure transactions with credit cards by adding a fingerprint scanner at the point-of-sale to obtain fingerprint data, so that a credit card company database can verify the fingerprint data against stored fingerprint information and verify the transaction accordingly. The method is integrated into the existing negotiation protocol between a point-of-sale system and a credit card company database, and uses a human fingerprint and a secure algorithm. The credit card company has the customer fingerprint for comparison on its existing database, and the existing credit card operation will be usual, with the fingerprint data added to it to authenticate and secure the operation via the communication media while making a point-of-sale purchase. In the case of an Internet purchase, the inventive method incorporates an authorization adaptor connected to the user PC, and once the user has made the purchase request, an encrypted communication is then commenced in which a token is sent by the credit card company to the user PC, requesting fingerprint data. The authorization adaptor provides the fingerprint scan, and sends the data to the user PC in encrypted form, for transfer to the credit card company by a secure communication, for authorization. The fingerprint scanner is based on use of a new sensor employing a technology that maps and matches fingerprints, using coincidence of the features (minutia) on as few as twelve similar points, to determine a match.
