• acquiring an RSSI of a signal transmitted from an RFID tag located near the gate;
• and
• determining whether or not an article specified by identification information read from the RFID tag has passed through the gate based on the specified flow line and the acquired RSSI.

A non-transitory computer readable medium storing a program for causing a computer to perform:

• a flow line specification step of specifying a flow line of a movement of an object in a predetermined area near a gate;
• a RSSI acquisition step of acquiring an RSSI of a signal transmitted from an RFID tag located near the gate;
