PROBLEM TO BE SOLVED: To release the lock of a function for utilizing an electronic value by using a method different from a conventional one. SOLUTION: A mobile communication terminal 50 has a control section 51, an IC chip section 56, and a motion detection section 57. The IC chip section 56 stores information, such as the electronic value. The motion detection section 57 has an acceleration sensor 57a and gyro sensor 57b, and detects the movement (position variation) of an own machine. The control section 51 stores pattern information indicating the pattern of the position variation of the own machine in an EEPROM 51d. The control section 51 detects the position variation of the own machine, allows the exchange of information at the IC chip section 56 when the detected position variation corresponds to position variation indicated by the pattern information stored in the EEPROM 51d. Otherwise, the control section 51 prohibits the exchange of information at the IC chip section 56. COPYRIGHT: (C)2009,JPO&INPIT
