(412) the said serial/parallel conversion equipment (23) in said the 2nd ISO7816 interface arrangement in the smart card that uses in the said mobile communication terminal sends four interface pin C4, C6, C7 and C8 in the 2nd ISO7816 interface arrangement in the smart card that uses in the mobile communication terminal to after a said bit serial data-switching is become four bit parallel data;

(413) said four bit parallel data through four interface pin C4 in the smart card that uses in the mobile communication terminal, C6, C7, C8 with said mobile communication terminal that they link to each other respectively in an ISO7816 interface arrangement in four interface pin C4, C6, C7 and C8 send the serial/parallel conversion equipment (13) in the ISO7816 interface arrangement in the said mobile communication terminal to;

(414) the said serial/parallel conversion equipment (13) in the ISO7816 interface arrangement in the said mobile communication terminal sends the ISO7816 interface controller (10) in the ISO7816 interface arrangement in the said mobile communication terminal to after said four bit parallel data-switching are become bit serial data; And

(415) the said ISO7816 interface controller (10) in the ISO7816 interface arrangement in the said mobile communication terminal is given the processor in the said mobile communication terminal with a said bit serial data transmission, realizes the smart card reading of data that said mobile communication terminal uses from said mobile communication terminal.
