Abstract: A self verifying transaction card having a self contained keyboard or keypad for entering a personal identification code, a simplified verification display comprised of light emitting diodes (LED's) which light up in a pre-determined configuration for validation of a verification check, a non-volatile memory with a stored code, and a self contained power supply. The card further contains circuitry for comparison of an entry with the stored code, with a pre-determined successive number of improper entries serving to disable the card from further identification functions and transactions. Clock/calendar timer and a contained microprocessor or microcontroller cause the verification function to be disabled at the expiration date of the card. The clock/calendar timer also provides a basis for uniquely correlating the time and date of a transaction to a changing verification display.
