A check-in determination apparatusconfigured to determine check-in indicating that a terminalhas entered a geofence which is a prescribed geographic area includes: a related geofence information storage unitconfigured to store related geofence information in which a related geofence which is another geofence is correlated with each geofence on the basis of a distance to the geofence; a check-in determination unitconfigured to determine check-in of the terminalsequentially with respect to each of the geofences. When it is determined that the terminalhas checked into one geofence, the check-in determination unitexcludes the related geofence correlated with the one geofence in the related geofence information stored by the related geofence information storage unitfrom determination targets in subsequent determination.

Check-in determining device

A check-in determination apparatusincludes: a determination history information storage unitconfigured to store determination history information for each terminal, in which position identifying information capable of identifying a position of the terminalwhen check-in of the terminalwith respect to the geofence was determined is correlated with geofence identifying information capable of identifying the geofence; a related geofence information storage unitconfigured to store related geofence information that correlates another geofence with each geofence; a position identifying information acquisition unitconfigured to acquire position identifying information of the terminal; and a check-in determination unitconfigured to determine check-in of the terminalwith respect to the geofence determined on the basis of the acquired position identifying information of the terminal, the stored determination history information, and the stored related geofence information.
