我正在尝试通过我的 LG P710 Optimus L7 2 读取智能卡。
我正在关注本教程
我可以选择“1PAY.SYS.DDF01”目录
我可以选择应用程序
但我无法执行“获取处理选项”它总是导致 6700 错误(Lc 或 Le 错误)
这是我的代码
NfcAdapter mNFCAdapter;
Intent intent;
PendingIntent pendingIntent;
private TextView mTextView;
String[][] techList;
IntentFilter[] filters = new IntentFilter[3];
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mTextView = (TextView) findViewById(R.id.title);
mNFCAdapter = NfcAdapter.getDefaultAdapter(this);
intent = new Intent(getApplicationContext(), getClass());
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
techList = new String[][]{
new String[]
{ MifareClassic.class.getName() },
new String[]
{ IsoDep.class.getName() }
};
filters[0] = new IntentFilter();
filters[0].addAction(NfcAdapter.ACTION_NDEF_DISCOVERED);
filters[0].addCategory(Intent.CATEGORY_DEFAULT);
// add type of tag data you want to have - here ndef -> plain text
try {
filters[0].addDataType(MIME_TEXT_PLAIN);
} catch (MalformedMimeTypeException e) {
e.printStackTrace();
}
filters[1] = new IntentFilter();
filters[1].addAction(NfcAdapter.ACTION_TAG_DISCOVERED);
filters[1].addCategory(Intent.CATEGORY_DEFAULT);
filters[2] = new IntentFilter();
filters[2].addAction(NfcAdapter.ACTION_TECH_DISCOVERED);
filters[2].addCategory(Intent.CATEGORY_DEFAULT);
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
String action = intent.getAction();
mTextView.setText(action);
Toast.makeText(getApplicationContext(), action, Toast.LENGTH_SHORT).show();
Tag tagFromIntent = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
IsoDep tagIsoDep;
if((tagIsoDep = IsoDep.get(tagFromIntent)) != null)
if(handleIsoDep(tagIsoDep))
return;
}
private boolean handleIsoDep(IsoDep tag){
try{
tag.connect();
tag.setTimeout(20);
byte[] responseAPDU;
//2PAY.SYS.DDF01
byte[] select_Dir = new byte[]{
(byte)0x00, (byte)0xa4, (byte)0x04, (byte)0x00, (byte)0x0e,
(byte)0x32, (byte)0x50, (byte)0x41, (byte)0x59, (byte)0x2e,
(byte)0x53, (byte)0x59, (byte)0x53, (byte)0x2e, (byte)0x44,
(byte)0x44, (byte)0x46, (byte)0x30, (byte)0x31
};
//Select CC Applet
byte[] select_Applet = new byte[]{
(byte)0x00, (byte)0xa4, (byte)0x04, (byte)0x00, (byte)7,
(byte)0xa0, (byte)0x00, (byte)0x00, (byte)0x00, (byte)0x04,
(byte)0x30, (byte)0x60
};
//Send GET PROCESSING OPTIONS command
byte[] Send_Get = new byte[]{
(byte)0x80,(byte)0xA8,(byte)0x00,(byte)0x00,(byte)0x02,
(byte)0x83,(byte)0x00,
(byte)0x00
};
responseAPDU = tag.transceive(select_Dir);
mTextView.setText(mTextView.getText() + handleResponse(responseAPDU));
这将返回 APDU 状态字 9000 -> 成功
responseAPDU = tag.transceive(select_Applet);
mTextView.setText(mTextView.getText() + handleResponse(responseAPDU));
这将返回 APDU 状态字 9000 -> 成功
responseAPDU = tag.transceive(Send_Get);
mTextView.setText(mTextView.getText() + handleResponse(responseAPDU));
而这个正在制造问题:它返回 6700 -> 错误的 Lc 或 Le
mTextView.setText(mTextView.getText() + "\n\nDone");
tag.close();
} catch (IOException e) {
e.printStackTrace();
return false;
}
return true;
}
函数handleResponse 只是将“responseAPDU”从二进制解析为十六进制并突出显示状态字
谁能告诉我出了什么问题?或者只是帮助我?
PS 对不起英语不好 ;)
作为对我的应用程序选择的回应,我得到:

6F -> FCI Template 29
84 -> DF Name 07 A0 00 00 00 04 30 60
A5 -> FCI Properietary Template 1E
50 -> Application Lable 07 4D 41 45 53 54 52 4F 5F 2D 04 64 65 6E
9F38 -> PDOL 03 9F 5C 08
BF0C -> FCI Issuer Data 05
9F4D -> Log Entry 02 0B
0A Additional Issuer Data
但我不知道要从 GET PROCESSING OPTIONS 将什么插入到数据字段中。
参考 EMV Book 3,“5.4 使用数据对象列表 (DOL) 的规则”一节中的指南。
那么我只需要设置数据字段 83 03 9F 5C 08
和 Lc = 5 吗?
