Abstract
A smart card (50) transfers information between the smart card and an external system (24) while having the capability of being accessed by a user. The smart card includes a microprocessing unit (MPU) (18) for executing instructions stored in memory, a display (28), coupled to the MPU, for displaying information, a keypad (26), coupled to the MPU and to the display, for entering data by the user, an interface (54,56) for transferring signals between smart card and the external system when the smart card is coupled to the external system, and photovoltaic cells (52) for providing power to the smart card when the smart card is exposed to light. The smart card does not require the use of a bulky and inflexible battery and since the solar cells used are flexible, the flexibility of the smart card is maintained.
