摘要

The present invention relates to a chip card comprising:
- an interface (112) to a master device (120),
- a single tasking processor (102) for receiving chip card commands from the master via the interface,
- first program instructions (106) for execution by the processor, the first program instructions implementing a chip card function,
- second program instructions (110) for execution by the processor, the second program instructions implementing an endless loop,
- third program instructions (108) for execution by the processor, the third program instructions being adapted to start execution of the second program instructions in response to a blocking signal.
