Embodiment Construction
[0058] This embodiment takes an intelligent terminal with a chip of a SIM card interface controller (ISO7816) as an example, but the chip does not have an integrated SIM card controller interface, but an intelligent terminal with a SIM card interface on the main board can also implement the present invention. The hardware principle of the SIM card interface formed by connecting the SIM card interface controller with the SIM card and an external power supply is as follows: figure 1 shown.
[0059] In this embodiment, the chip is internally integrated with a SIM card interface controller (SIM), which can store the data sent by the MCU (microprocessing controller) through the bus in the sending buffer, and put it outside in a signal form conforming to the ISO7816 standard. Port, while receiving the data returned by the SIM card and storing it in the internal buffer. The chip is based on the ISO7816 protocol standard and provides SIM card interface standard signals. Its SIMCK pin...
