1. the data processing equipment of IC medium, this device under synchronous communication and asynchronous communication protocol with the IC media communication, this device comprises:

  • keep the IC medium, and the 1st feedway (15 of the 1st clock signal that communicates being provided for the IC medium that kept by synchronous communications protocol, 16, S104);

    Based on the 1st clock signal, according to the data of portable IC medium output, judge portable IC medium use synchronous communications protocol still be the device that communicates of asynchronous communication protocol (11, S105, S106, S117, S107, S108, S113, S109);

    When judgment means judge to be used synchronous communications protocol, according to synchronous communications protocol continue to portable IC medium carry out the processing of back device (11, S110, S111);

    When judgment means judge to be used asynchronous communication protocol, give the 2nd feedway that portable IC medium provide the 2nd clock signal that communicates by asynchronous communication protocol (11, S114, S115, S116, S118).
