1. A communication system, comprising:

  • an information storage medium;

    an electromagnetic induction communication device; and

    a relay communication device disposed between the information storage medium and the electromagnetic induction communication device, the communication system performing communication while conveying the information storage medium,wherein the information storage medium comprises;

    an IC chip configured to be communicable through electromagnetic induction or electromagnetic coupling; and

    a pair of electrically conductive plates connected to the IC chip,wherein the relay communication device comprises;

    a relay loop antenna; and

    a pair of electrically conductive rails which is connected to both ends of the relay loop antenna, placed along a conveyance direction of the information storage medium, and electrostatically coupled with the pair of electrically conductive plates of the information storage medium, andwherein the electromagnetic induction communication device comprises;

    a communication loop antenna configured to communicate with the relay loop antenna through electromagnetic induction or electromagnetic coupling; and

    a control unit configured to execute processing of communication with the IC chip of the information storage medium, when the communication loop antenna communicates with the relay communication device through electromagnetic induction or electromagnetic coupling, and the relay communication device electrostatically couples with the information storage medium.
