1. a data communication system, it is configured at read/write device, can carries out the integrated circuit card of radio communication and carry out data communication by the information processing terminal three party that wireline interface is connected to described integrated circuit card with cordless and described read/write device, and described data communication system comprises:

  • Described read/write device, it has;

    Read/write wireless controlled clamp dog, it is configured to the radio communication of output signal carrier wave control and described integrated circuit card;

    Described integrated circuit card, it has;

    Integrated circuit wireless controlled clamp dog, it is configured to according to detecting from the described signal carrier of described read/write wireless controlled clamp dog output, the radio communication of beginning control and described read/write device;

    AndThe described information processing terminal, it has;

    Piece is accepted in request, and it is configured to accept the data transmission requests from user,DSB data store block, it is configured to store data, andData transmission block, it is connected to described integrated circuit wireless controlled clamp dog by wireline interface, described data transmission block is configured in response to accept the data transmission requests of piece from described request, and the transfer of data in data transfer request signal and described DSB data store block is arrived to described integrated circuit wireless controlled clamp dog;

    Wherein,When receiving from the data transfer request signal of described data transmission block and data, described integrated circuit wireless controlled clamp dog switches to the communication pattern of described integrated circuit wireless controlled clamp dog the continuous communiction pattern that can transmit continuously or receive data, in identical timing, described data transfer request signal and described transfer of data are arrived to described read/write wireless controlled clamp dog, and do not wait for the order from described read/write wireless controlled clamp dog;

    AndDescribed read/write wireless controlled clamp dog is used described data transfer request signal from described integrated circuit wireless controlled clamp dog as triggering, the communication pattern of described read/write wireless controlled clamp dog is switched to described continuous communiction pattern, and receive the described data from described integrated circuit wireless controlled clamp dog.
