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......
答案 0 :(得分:6)
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();
}

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();
}
答案 4 :(得分:0)
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,获取卡片图片,使用良好的java ocr库扫描图片内容(例如http://ocr4j.sourceforge.net/)并搜索(通常)16位数字序列XXXX- XXXX-XXXX-XXXX,然后您将使用java从任何EMV卡获取PAN。
