Abstract

Memory elements are physically distributed throughout a smart card. Each of these memory elements has a preset value or preset programmable value. Before release of information, the preset value of each memory element is checked to determine if the smart card has been tampered with by such methods as radiating or microwaving the card. If tampering is detected, information is barred from being released.
