A method to increase security of transactions at point of sale, i.e. POS terminals (20) by incorporating fingerprint verification. Key minutiae points from the authorized user's fingerprints (24) are extracted and stored as a template; a complete fingerprint is never stored. Minutiae extracted from the live fingerprint of a user are matched against the stored template. Upon a positive match of the two, the transaction is allowed to proceed.
