A repeater apparatus (20) includes a network communication unit (211) that acquires, from a server (30) through a network (40), first terminal identification information (302) for identifying a terminal to be controlled (10) and control information (301) for controlling the terminal to be controlled, a near-field communication unit (204) that acquires, by near-field communication from the terminal (10), second terminal identification information (303) for identifying the terminal (10) and stored in the terminal (10), and a comparison unit (208) that decides whether the first terminal identification information (302) agrees with the second terminal identification information (303). The near-field communication unit (204) transmits the control information (301) to the terminal (10) by near-field communication, in the case where the comparison unit (208) decides that the first terminal identification information (302) agrees with the second terminal identification information (303).
