More Information
Summary:To provide a portable communication terminal which can improve security. A mobile telephone device (1) includes: a RFID chip (52) which performs magnetic field communication based on a signal coming from outside; a NAND flash memory (73) which stores use-enabled/disabled information indicating whether the RFID chip (52) can be used; and a CPU (72) which updates the use-enabled/disabled information. When a signal comes from outside, the RFID chip (52) judges whether to perform a predetermined process according to predetermined information based on the use-enabled/disabled information stored in the NAND flash memory (73).
