Abstract
The method and system for the invention utilizes any of a number of 'proofs of legitimacy' to generate and verify a personal identification card. A card is generated by computing a digital signature of a non-secret password. The password and the digital signature are then encoded and stored on a magnetic stripe or other memory device of the card. To effect a transaction, the digital signature on a received card must be shown to have been generated from the password on the received card. The password preferably includes a digitized photograph of the authorized cardholder which is capable of being displayed at the transaction terminal. This enables the operator of the terminal to verify the identity of the cardholder by visual inspection.
