A communication apparatus that communicates with a terminal by near-field communication and with a server through a network, the communication apparatus comprising: a network communication unit configured to acquire, from the server through the network, first terminal identification information for identifying a terminal to be controlled and control information for controlling the terminal to be controlled; a first near-field communication unit configured to acquire, by near-field communication from a terminal to communicate with, second terminal identification information for identifying the terminal to communicate with, the second terminal identification information being stored in the terminal to communicate with; and a comparison unit configured to decide whether the first terminal identification information and the second terminal identification information agree with each other, after the control information is acquired/ characterised in that the first near-field communication unit is configured to transmit the control information by near-field communication to the terminal to communicate with, in the case where the comparison unit decides that the first terminal identification information and the second terminal identification information agree with each other, wherein the acquisition of the second terminal identification information by near-field communication and the transmission of the control information by near-field communication to the terminal to communicate with, are performed by the first near-field communication unit in a period after the terminal to communicate with and the communication apparatus are brought together to within a distance that allows communication by the near-field communication and before the terminal to communicate with and the communication apparatus are separated beyond the distance. a network communication unit configured to acquire, from the server through the network, first terminal identification information for identifying a terminal to be controlled and control information for controlling the terminal to be controlled; a first near-field communication unit configured to acquire, by near-field communication from a terminal to communicate with, second terminal identification information for identifying the terminal to communicate with, the second terminal identification information being stored in the terminal to communicate with; and a comparison unit configured to decide whether the first terminal identification information and the second terminal identification information agree with each other, after the control information is acquired/ characterised in that the acquisition of the second terminal identification information by near-field communication and the transmission of the control information by near-field communication to the terminal to communicate with, are performed by the first near-field communication unit in a period after the terminal to communicate with and the communication apparatus are brought together to within a distance that allows communication by the near-field communication and before the terminal to communicate with and the communication apparatus are separated beyond the distance.
