<P>PROBLEM TO BE SOLVED: To obtain a portable smart card device, a method for executing a program code by using the smart card device, and a computer readable storage medium including an instruction to the smart card device. <P>SOLUTION: The smart card device includes: an interface for presenting a smart card function to a host system and also receiving a program execution command from the host system; a nonvolatile memory; an executable memory; a copy mechanism such as an internal copy mechanism for copying a program code from the nonvolatile memory to the executable memory; and a program execution mechanism for executing the program code. An ISO7816 conforming interface, a USB interface, and an MMC interface are listed as a proper interface. The smart card function includes a SIM function and/or a USIM function. When only a portion of an arbitrarily copied executable code exists in the executable memory, the execution of the program code is started. <P>COPYRIGHT: (C)2012,JPO&INPIT |
