Abstract: A self-authenticating credit card includes an input device for entering a PIN. The PIN is accepted by a micro-controller that uses the entered PIN as an encryption key for decrypting stored account information. A portion of the account information includes data, that when decrypted, contains an image that is rendered on an integral display, with account information sent to a transaction terminal. A timer is used to limit access to account data while in the unlocked state.

Abstract: A portable media system for a host computer system, and method of operation thereof, that includes: a controller in the portable media system for communicating clear information between the portable media system and the host computer system; and an encryption system in the portable media system for providing an encryption algorithm for the controller to decrypt cipher information for the host computer system.
