1. A communication apparatus that communicates with a server connected via a network and also communicates, by using near-field communication, with a plurality of external devices, each of the external devices being provided with a Radio Frequency Identification (RFID) tag, the communication apparatus comprising:

  • a selection acceptance unit that accepts a selection by a user of a target external device performing the near-field communication among the plurality of external devices, the target external device having a surface on which a guide pattern representing a position of an antenna performing the near-field communication is formed;

    a guide pattern acquisition unit that transmits external device identification information for identifying the target external device selected by the user to the server, and acquires, from the server, a guide pattern image having the same shape as the guide pattern corresponding to the external device identification information;

    a loop antenna that outputs a polling signal by near-field communication to the RFID tag provided in the target external device and receives a polling response by near-field communication from the RFID tag provided in the target external device that has received the polling signal;

    a display unit provided on a side of the communication apparatus opposite an orientation in which the loop antenna transmits the polling signal and receives the polling response;

    a communication apparatus identification information storing unit that stores communication apparatus identification information for identifying the communication apparatus;

    a position information acquisition unit that transmits the communication apparatus identification information stored in the communication apparatus identification information storing unit to the server and acquires, from the server, antenna position information that represents a position of the loop antenna in the communication apparatus and that corresponds to the communication apparatus identification information; and

    a position information storing unit that stores the acquired antenna position information, whereinthe display unit displays the guide pattern image acquired by the guide pattern acquisition unit as a guide pattern indicating the position of the loop antenna on the basis of the antenna position information which is stored in the position information storing unit, and fixedly displays the guide pattern image at the position of the loop antenna included in the communication apparatus regardless of a movement of the communication apparatus, within a period in which the loop antenna outputs the polling signal to the target external device.
