1. a cipher-code input method, is characterized in that, comprising:

  • Receive the operational order that card reader sends;

    Whether detect described operational order is cryptographic check instruction;

    If described operational order is not cryptographic check instruction, described operational order is sent to smart card;

    If described operational order is described cryptographic check instruction, receive the password of user'"'"'s input;

    The cipher seal of described user'"'"'s input is installed in described cryptographic check instruction;

    The cryptographic check instruction that is packaged with described user and inputs password is sent to smart card;

    Receive the execution result of the described cryptographic check instruction that described smart card returns;

    The execution result of described cryptographic check instruction is sent to described card reader.
