我使用的是读写器 acr38f，我的智能卡是 SLE4418。如何在智能卡中读取和写入文本？
例如:Hello World!
apdu = [0XFF, 0X20,0x00,0x00,0x02, 0x00, 0x00]
response, sw1, sw2 = cardservice.connection.transmit( apdu )
apdu = [0XFF,0xA4,0x00,0x00,0x01,0x05] response, sw1, sw2 = cardservice.connection.transmit( apdu ) apdu = [0XFF,0XB2,0X00,0xA7,0X09] response, sw1, sw2 = cardservice.connection.transmit( apdu ) print response apdu = [0XFF, 0XD0,0x00,0xA7,0x09,0xA7,0x02,0xA7,0x02,0xA7,0x02,0xA7,0x02,0xA7] response, sw1, sw2 = cardservice.connection.transmit( apdu )

最佳答案
我没有测试这个的硬件，但这应该可以帮助你:
与智能卡通信涉及发送 APDU (智能卡应用协议(protocol)数据单元) 命令和接收 APDU 响应。
命令 APDU 通过读写器(您的 ACR38F)发送，由一个 4 字节的 header 和后跟数据(以及有关数据大小和响应大小的信息)组成
Field Len Description
--------------------------------------------
CLA (1) Instruction Class
INS (1) Instruction Code
P1-P2 (2) Instruction Parameters
Lc (0,1,3) Number of data bytes to follow
DATA (*) Data to be transmitted
Le (0-3) Maximum response bytes
响应包括:
Field Len Description
--------------------------------------------
DATA (*) Data to be transmitted
SW1-SW2 (2) Command status
在 SLE4418, in order to write data, 的情况下值应如下所示:
- CLA = 00
- INS = D6
- P1 = 存储字节的内存地址偏移的 MSB
- P2 = 存储字节的内存地址偏移的 LSB
- Lc = 要存储的字节长度
- DATA = 要存储的数据
- Le =(空)
因此在代码中:
WRITE = [0x00, 0xD6]
STARTMSB = [0x00] #change to where on the card you would like to write
STARTLSB = [0x00] #same here
MEM_L = [0x01]
DATA = [0x01]
cardservice.connection.connect()
apdu = READ + STARTMSB + STARTLSB + MEM_L + DATA
response1, sw1, sw2 = self.cardservice.connection.transmit( apdu )
