1. the implementation method of an information transmission is characterized in that, comprising:

  • Smart card is notified to main control equipment with the mode of operation of its support;

    Described smart card receives the clock frequency that described main control equipment returns, wherein, the described clock frequency of returning is determined according to the described mode of operation of notice by described main control equipment, determine under the situation of the clock frequency that the described smart card support external world provides according to the mode of operation of described smart card notice at described main control equipment, the clock frequency that described main control equipment returns is the second clock frequency, wherein, described second clock frequency is higher than first clock frequency that described smart card acquiescence is supported;

    Described smart card is judged the described second clock frequency that itself whether can support that described main control equipment returns, in judged result is under the situation that is, described smart card and described main control equipment are that the clock control signal of described second clock frequency carries out information transmission based on frequency;

    Perhaps, described smart card is that the clock control signal of described second clock frequency carries out frequency division to frequency, obtain the clock control signal that frequency is described first clock frequency, and described smart card is the clock control signal of described first clock frequency based on frequency, and described main control equipment is the clock control signal of described second clock frequency based on frequency.
