Method for controlling the execution of an applet for an ic card

A method for controlling execution of an applet for an IC Card comprising a java card platform, the method comprising:

• downloading the applet to a memory portion of the IC Card;
• detecting an identification number in the memory portion of the IC Card;
• and
• executing the applet, through the java card platform, in a normal mode if the identification number is detected and in a restricted mode if the identification number is not detected.

A method for controlling execution of a java card applet for an IC Card comprising a java card platform, the method comprising:

• downloading the java card applet to a memory portion of the IC Card;
• detecting an identification number in a secret memory portion of the IC Card;
• and
• executing the java card applet, through the java card platform, in a normal mode if the identification number is detected and in a restricted mode if the identification number is not detected.

An IC Card comprising:

• an IC card substrate;
• a memory on the IC card substrate to store a java card platform and an applet and able to store an identification number;
• and
• a processor on the IC card substrate;
• said processor to cooperate with the memory to detect the identification number and to execute the applet, through the java card platform, in a normal mode if the identification number is detected and in a restricted mode if the identification number is not detected.

An IC Card comprising:

• an IC card substrate;
• a memory on the IC card substrate to store a java card platform and a sim toolkit applet, and having a secret portion to store an identification number;
• and
• a processor on the IC card substrate;
• said processor to cooperate with the memory to detect the identification number and to execute the sim toolkit applet, through the java card platform, in a normal mode if the identification number is detected and in a restricted mode if the identification number is not detected.
