接触式 的ic卡的管脚是一样的吧，那要看iso7816-1的。

触点朝向您，触点在下方

下一行从左到右为1,2,3,4，上一行从左到右为5,6,7,8

Contact  Designation  Use  
C1  Vcc  Power connection through which operating power is supplied to the microprocessor chip in the card  
C2  RST  Reset line through which the IFD can signal to the smart card's microprocessor chip to initiate its reset sequence of instructions  
C3  CLK  Clock signal line t hrough which a clock signal can be provided to the microprocessor chip. This line controls the operation speed and provides a common framework for data communication between the IFD and the ICC  
C4  RFU  Reserved for future use  
C5  GND  Ground line providing common electrical ground between the IFD and the ICC  
C6  Vpp  Programming power connection used to program EEPROM of first generation ICCs.  
C7  I/O  Input/output line that provides a half-duplex communication channel between the reader and the smart card  
C8  RFU  Reserved for future use
