Abstract: A communication device includes: a distance information acquisition unit configured to acquire distance information indicating a distance to a communication target; a setting information acquisition unit configured to acquire setting information including a communication distance; and a communication unit configured to communicate with the communication target. The distance information acquisition unit acquires the distance information after the communication unit establishes connection with the communication target. The communication unit cuts the connection with the communication target when the distance information does not satisfy the communication distance included in the setting information.
