1. A check-in determination apparatus configured to determine check-in indicating that a terminal has entered a geofence which is a prescribed geographic area, comprising processing circuitry configured to:
store related geofence information in which a related geofence which is another geofence is correlated with each of geofences on the basis of a distance to the geofence; and
determine check-in of the terminal sequentially with respect to each of the geofences, wherein
when it is determined that the terminal has checked into one geofence, the processing circuitry determines that the terminal has also checked into the related geofence correlated with the one geofence in the stored related geofence information and excludes the related geofence correlated with the one geofence in the stored related geofence information from determination targets in subsequent determination.
