APDU command to read credit card data from visa Paywave NFC enabled card using Samsung Galaxy S4

Question

  byte[] APDUCommand = { 
            (byte) 0x00, // CLA Class           
            (byte) 0xA4, // INS Instruction     
            (byte) 0x04, // P1  Parameter 1
            (byte) 0x00, // P2  Parameter 2
            (byte) 0x0A, // Length
            0x63,0x64,0x63,0x00,0x00,0x00,0x00,0x32,0x32,0x31 // AID
        };


    Intent intent = getIntent();
    Tag tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
    IsoDep iso = IsoDep.get(tag);        
    iso.connect();

    byte[] result = iso.transceive(APDUCommand);

I am using the above code to read VisaPayWave NFC card details(card holder's name, expiry date, card number etc) using samsung galaxy s4. The output that i am getting is [106,-126]. I think the APDU command i am using is not correct. Kindly suggest the correct command.

Change your APDU command definition

byte[] APDUCommand = { 
        (byte) 0x00, // CLA Class           
        (byte) 0xA4, // INS Instruction     
        (byte) 0x04, // P1  Parameter 1
        (byte) 0x00, // P2  Parameter 2
        (byte) 0x07, // Length
        (byte) 0xA0,0x00,0x00,0x00,0x03,0x10,0x10 // AID
    };
