PROBLEM TO BE SOLVED: To reduce a workload and a work time for searching for a reading object with an RFID tag attached thereto.SOLUTION: A portable terminal 10 acquires reading direction information of an RFID reader/writer part 18 when an RFID tag 30 is read by an azimuth magnetic needle part 21, and associates position information when the RFID tag 30 detected by a motion sensor 19 is read, and the acquired reading direction information with identification information of the RFID tag 30 as previous reading position information and previous reading direction information to be stored in a flash memory 17. In addition, the portable terminal 10 acquires the reading direction information of the RFID reader/writer part 18 from the direction information detected by the azimuth magnetic needle part 21, and indicates guidance information showing the previous reading position information and the previous reading direction information stored in the flash memory 17 to the position information detected by the motion sensor 19 and the acquired reading direction information. |
