我需要使用智能卡读卡器读取Maestro / Mastercard的帐号。我正在使用Java 1.6及其javax.smartcardio包。我需要发送APDU命令,它会询问存储在卡芯片上的EMV应用程序的PAN号。问题是,我找不到常规的字节数组来构造APDU命令,它将在任何地方返回所需的数据......

有帮助吗?

解决方案

您不需要进一步包装APDU。 API层应该处理这个问题。

看起来0x6D00响应只意味着应用程序不支持INS。

现在只是进行故障排除,但您确实选择了MasterCard应用程序,对吗?

即。像这样的东西:

void selectApplication(CardChannel channel) throws CardException {
  byte[] masterCardRid = new byte[]{0xA0, 0x00, 0x00, 0x00, 0x04};
  CommandAPDU command = new CommandAPDU(0x00, 0xA4, 0x04, 0x00, masterCardRid);
  ResponseAPDU response = channel.transmit(command);
  return response.getData();
}

其他提示

这是一些工作示例:

CardChannel channel = card.getBasicChannel(); 

 byte[] selectMaestro={(byte)0x00, (byte)0xA4,(byte)0x04,(byte)0x00 ,(byte)0x07 ,(byte)0xA0 ,(byte)0x00 ,(byte)0x00 ,(byte)0x00 ,(byte)0x04 ,(byte)0x30 ,(byte)0x60 ,(byte)0x00};
  byte[] getProcessingOptions={(byte)0x80,(byte)0xA8,(byte)0x00,(byte)0x00,(byte)0x02,(byte)0x83,(byte)0x00,(byte)0x00};
  byte[] readRecord={(byte)0x00,(byte)0xB2,(byte)0x02,(byte)0x0C,(byte)0x00};

  ResponseAPDU r=null;

   try {
     ATR atr = card.getATR(); //reset kartice

      CommandAPDU capdu=new CommandAPDU( selectMaestro   );

       r=card.getBasicChannel().transmit( capdu );

      capdu=new CommandAPDU(getProcessingOptions);
      r=card.getBasicChannel().transmit( capdu );


      capdu=new CommandAPDU(readRecord);
      r=card.getBasicChannel().transmit( capdu );

这适用于Maestro卡,我可以读取PAN编号,但现在我需要读取MasterCard的PAN编号。我不知道我应该更改读取记录APDU还是选择应用程序APDU。有人熟悉APDU吗?

atr = open();
prints(atr);

prints("[Step 1] Select 1PAY.SYS.DDF01 to get the PSE directory");
cmd = new ISOSelect(ISOSelect.SELECT_AID, EMV4_1.AID_1PAY_SYS_DDF01);
card_response = execute(cmd);
prints(card_response);
SFI = NumUtil.hex2String((byte)((1 < < 3) | 4));

// try SFI 1 record 1
prints("[Step 2] Send READ RECORD with 0 to find out where the record is");
read = new EMVReadRecord(SFI, "01", "00");
card_response = execute(read);
prints(card_response);
byte_size = NumUtil.hex2String(card_response.getStatusWord().getSw2());

prints("[Step 3] Send READ RECORD with 1C to get the PSE data");
read = new EMVReadRecord(SFI, "01", byte_size);
card_response = execute(read);
prints(card_response);
// the AID is A0000000031010
prints("[Step 4] Now that we know the AID, select the application");

cmd = new ISOSelect(ISOSelect.SELECT_AID, "A0000000031010");
card_response = execute(cmd);
prints(card_response);
prints("[Step 5] Send GET PROCESSING OPTIONS command");

cmd = new EMVGetProcessingOptions();
card_response = execute(cmd);
prints(card_response);

// SFI for the first group of AFL is 0C

prints("[Step 6] Send READ RECORD with 0 to find out where the record is");
read = new EMVReadRecord("0C", "01", "00");
card_response = execute(read);
prints(card_response);
byte_size = NumUtil.hex2String(card_response.getStatusWord().getSw2());

prints("[Step 7] Use READ RECORD with the given number of bytes to retrieve the data");
read = new EMVReadRecord("0C", "01", byte_size);
card_response = execute(read);
prints(card_response);

data = new TLV(card_response.getData());

close();

您需要构造一个CommandAPDU对象并将其传递给transmit() - 命令。

您应该能够在智能卡的文档中找到精确的命令,但这是一个例子:

byte[] readFile(CardChannel channel) throws CardException {
  CommandAPDU command = new CommandAPDU(0xB0, 0x60, 0x10, 0x00);
  ResponseAPDU response = channel.transmit(command);
  return response.getData();
}

您是否尝试在文档中查找0x6D00的含义?看起来它可能意味着不支持ENVELOPE命令。您是否尝试使用T = 0协议而不是T = 1?

我不希望我的例子在你的卡上工作。我不知道Maestro / MasterCard支持哪些APDU,所以我不能给你一个有效的例子。

尝试给命令一个明确的预期长度,如下所示:

byte[] readPan(CardChannel channel) throws CardException {
  CommandAPDU command = new CommandAPDU(0x00, 0xB2, 0x5a, 0x14, 250);
  ResponseAPDU response = channel.transmit(command);
  return response.getData();
}

如何使用扫描仪,获取卡片的图片,使用良好的java ocr库扫描图片内容(如 http://ocr4j.sourceforge.net/ 例如)并搜索(通常)16位数序列XXXX-XXXX-XXXX-XXXX,然后您将使用java从任何EMV卡获取PAN。
