Android Mifare Classic authentication fails

votes

I am trying to read a Mifare Classic card and I fail at the authentication step. I've tried both authentication methods, A and B.

I'm also familiar with this question and I've also read this page where you'll find a reference to a list of phones that can't read Mifare Classic cards/tags.

The phone I'm using is LG Optimus L5 II E460. Have any of you used it?

Is there a way to check inside my application if the phone can read Mifare Classic cards/tags?

Is there a way to lock a Mifare Classic card/tag with a personal key and not the MifareClassic.KEY_DEFAULT ?

Is there a way to format a Mifare Classic card/tag? By format I mean erase everything from the card/tag, like a Factory Reset.

Here is my code:

public class NFC_Writer extends AppCompatActivity {

private NfcAdapter mNfcAdapter;
private Tag mTag;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_nfc__writer);

    mNfcAdapter = NfcAdapter.getDefaultAdapter(this);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_nfc__writer, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

@Override
protected void onResume() {
    super.onResume();

    enableForegroungDispatchSystem();
}

@Override
protected void onPause() {
    super.onPause();

    disableForegroungDispatchSystem();
}

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);

    if(intent.hasExtra(NfcAdapter.EXTRA_TAG))
    {
        Toast.makeText(this, "We received a NFC intent!", Toast.LENGTH_SHORT).show();

        mTag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);

        String[] techList = mTag.getTechList();

        //writeCard(message);

        EditText editText = (EditText) this.findViewById(R.id.entered_text);
        String message = editText.getText().toString();

        NdefMessage ndefMessage = createNdefMessage(message);

        writeNdefMessage(mTag, ndefMessage);
    }
}

    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);

    IntentFilter[] intentFilters = new IntentFilter[] {};

    mNfcAdapter.enableForegroundDispatch(this, pendingIntent, intentFilters, null);

        }

        ndefFormatable.connect();
        ndefFormatable.format(ndefMessage);

private void writeCard(String content){
    MifareClassic mfc = MifareClassic.get(mTag);

    try{
        mfc.connect();
        {
            boolean authA = mfc.authenticateSectorWithKeyB(0, MifareClassic.KEY_DEFAULT);

        mfc.close();
    }
    catch(Exception ioe) {
        Log.e("writeCard : ", ioe.getMessage());
    }
}
}

I've tried to use NdefFormatable to format the card in order to work with Ndef but an IOException in thrown when I call the NdefFormatable::connect() function.

When I try using the MifareClassic class I always receive false when I call function authenticateSectorWithKeyB or authenticateSectorWithKeyA.

I've tried both this methods because when I call Tag::getTechList() I receive the following list: android.nfc.tech.NfcA, android.nfc.tech.MifareClassic, android.nfc.tech.NdefFormatable;

What have you tried so far? What card do you use to authenticate to the card? At which point does that code fail? – Michael Roland
I've edited the question. Please have a look there. – Cosmin
Is the card empty? Could you successfully write to the card using Ndef (not NdefFormatable)? – Michael Roland
No, the card that I'm using right now is not empty. It has been used before but not by me. I believe this this is the source of the problem. I read on some website (I don't remember which one) that after you write a Mifare card the authentication password is changed automatically. Is that right? – Cosmin
Tomorrow I'll be able to test with some fresh new cards. – Cosmin

After all the research I've done I concluded that there is a compatibility problem.

I say this because I managed to read/write NTAG216 cards which have a NTAG21X chip and as far as I know come as a replacement for ABK-1001MF cards which have a MIFARE S50 chip, the first type of cards I tried to read/write, using the same type of phone LG Optimus L5 II E460.

My conclusion is strengthened by the fact that when I call:

getPackageManager().hasSystemFeature("com.nxp.mifare");

the return is false.

Thanks everyone for the help!
