Movement-history management device, movement-history management method, and recording medium

A movement-history management method comprising:

• detecting, by a computer, a position of an RFID tag based on a signal received from the RFID tag;
• detecting, by a computer, movement of the RFID tag based on a position history of the RFID tag;
• and
• associating, by a computer, the position history of the RFID tag detected to have moved with a position history of another RFID tag detected to have moved in a manner similar to the RFID tag detected to have moved, as a group of movement histories.

A non-transitory recording medium that records a movement-history management program for causing a computer to execute processing, the processing comprising:

• detecting a position of an RFID tag based on a signal received from the RFID tag;
• detecting movement of the RFID tag based on a position history of the RFID tag;
• and
• associating the position history of the RFID tag detected to have moved with a position history of another RFID tag detected to have moved in a manner similar to the RFID tag detected to have moved, as a group of movement histories.
