Embodiment Construction
[0012] As shown in the figure, the NFC-SIM card chip emulator 1 of the present invention includes an emulation chip 2 and a detection control module 3 . The emulation chip 2 is used to simulate the function of the product chip, and the user program is executed in the emulation chip 2 . The emulation chip 2 has 7816 pins conforming to the ISO7816 protocol, including a reset input pin RST_IN, a clock input pin CLK_IN, and a bidirectional data pin IO_A, which are respectively connected to the reset output pin RST_OUT and the clock output pin of the terminal card reader device 4. The pin CLK_OUT and the bidirectional data pin IO_B are connected to enable 7816 communication. Described simulation chip 2 uses the power supply provided by NFC-SIM card chip emulator 1, does not use the power supply provided by terminal card reading device 4 (the product card uses the power supply provided by terminal card reading device 4). The emulation chip 2 also has a SWP pin SWP_1 conforming to t...
