Abstract
An IC card has a CPU and a memory for storing first and second programs. The CPU executes a plurality of instruction in accordance with the first and second programs. The second program is provided by a card manufacturer. A card issuer, such as bank, provides a first program which operates on the second program. The IC card further includes a supervising device for determining when the instructions in the first program address instructions in the second program. When the second program is addressed during operation of the first program, the CPU is interrupted.
