PROBLEM TO BE SOLVED: To easily transmit data to a host computer by preventing the data from being stolen or altered. SOLUTION: A write-only arithmetic processing part 31 which is connected to an external device by lead-out lines 51, 53, 55, and 57 and a nonvolatile memory 35 which is connected to the write-only arithmetic process part 31 and stores data are provided. Further, a read-only arithmetic process part 33 which reads data out of the nonvolatile memory 35 and a transmitting/receiving circuit 37 and an antenna coil 15 which send the data read out by the read-only arithmetic process part 33 are provided. Further, a power source part 41 which allows the read-only arithmetic process part 33 and nonvolatile memory 35 to operate with an external electromagnetic wave received by the antenna coil 15 is also provided to obtain the noncontact output interface 10. |
