PROBLEM TO BE SOLVED: To show a user a tag position of an RFID tag using one reading part of the RFID tag.SOLUTION: A portable terminal 10 makes an RFID reader writer part 18 as a reading part read individual identification information of an RFID tag multiple times, and stores, in a storage part 17, the read individual identification information, multiple response time of the reading measured at the reading of the individual identification information, and positional information and azimuth information of the portable terminal 10 obtained by a motion sensor 19 and an azimuth magnetic needle part 21, in association with one another. On the basis of the multiple response time, the positional information and the azimuth information corresponding to the individual identification information, stored in the storage part 17, the portable terminal 10 calculates tag positional information indicating a position of the RFID tag of the individual identification information, and displays the tag positional information at a display part 14. |
