A communication system, a communication apparatus, and a communication method are provided. A communications apparatus includes a generation unit for generating a transmission message sent to a different communications apparatus and effective for only one transmission, a first communications units for communicating with the different communications apparatus using Near Field Communication, a second communications unit for communicating with the different communications apparatus via a predetermined communication channel, and a control unit for controlling the communication functions. The second communications unit transmits the transmission message generated by the generation unit and receives a different transmission message transmitted from the different communications apparatus via the predetermined communication channel. The first communications unit receives a message transmitted from the different communications apparatus and transmits the different transmission message to the different communications apparatus using Near Field Communication. The control unit determines whether the message received by the first communications unit is equal to the transmission message transmitted by the second communications unit.
