  The user requests a backup of the data stored in the storage unit 6 from the operation unit 7 of the mobile terminal device 100 (step S401). When the data backup function is activated, the mobile terminal device 100 transmits a radio wave of a predetermined frequency from the antenna 5 to the charging device 200 from the RFID unit 4 (step S402). The charging device 200 receives the radio wave transmitted from the mobile terminal device 100 with the antenna 28 (step S403). As a result, power is generated in the RFID unit 27 of the charging apparatus 100, and the RFID unit 27 can transmit data stored in the storage unit 24 using this power, and waits for a request for a transmission operation. (Step S404). Next, the mobile terminal device 100 transmits identification information unique to the device itself to the charging device 200 from the RFID unit 4 via the antenna 5 (step S405). The charging device receives identification information unique to the mobile terminal device 100 via the antenna 28 (step S406), and determines whether or not the identification information stored in the storage unit 24 matches the received identification information. (Step S407). If the identification information stored in the storage unit 24 and the received identification information do not match (step S407 / NO), the backup operation of the storage unit 6 ends without being executed. On the other hand, when the identification information stored in the storage unit 24 matches the received identification information (step S407 / YES), the backup operation of the storage unit 6 is executed (step S408). The data to be backed up in the storage unit 6 is transmitted from the RFID unit 4 to the charging device 200 via the antenna 5, and the data received by the antenna 28 is stored in the storage unit 24 using the power generated in the RFID unit 27. Is done.

  According to this process, after confirming whether or not the identification information unique to the mobile terminal device 100 stored in each of the mobile terminal device 100 and the charging device 200 matches, the data stored in the mobile terminal device 100 Therefore, it is possible to prevent the data stored in the mobile terminal device 100 from being stored in the charging device 200 without permission.
