ABSTRACT:
A chip card comprises a microprocessor able to execute a program recorded in memory and one or more removable portions, which may be, for example, pre-cut portions. The execution of the program can be modified by tearing off or cutting one or more of these portions. The program may include an instruction to test a register whose contents depend on the presence of one of the removable portions. Many applications, such as an electronic visiting card, are possible with the disclosed chip card.
