我正在使用读写器 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]

响应,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 )

我没有硬件来测试这个,但这应该让你继续:

与智能卡通信涉及发送 APDU (智能卡应用协议数据单元)命令和接收 APDU 响应。

命令 APDU 通过读/写器(您的 ACR38F)发送,包含一个 4 字节的标头,后跟数据(以及有关数据大小和响应大小的信息)

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

对于SLE4418,为了写入数据,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
  • 乐=(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 )
