Reading PACS (raw Wiegand) data with Omnikey 5022


I'm developing a Java application that connects to HID Omnikey 5022 card reader. What I need is reading PACS bits (raw Wiegand data).

I have exactly the same problem with this question, I also can see the data with PACS Probe application:

How to read Smart Card data

Unfortunately the provided answer to that is not working for me.

This is what I get from PACS Probe:

I have already tried the command I found in Omnikey 5023 guide, surprisingly it returns some data but it's not what I need.

That command is:

commandAPDU = new CommandAPDU(new byte[] { (byte) 0xFF, (byte) 0x70, (byte) 0x07, (byte) 0x6B, (byte) 0x07,
                (byte) 0xA0, (byte) 0x05, (byte) 0xBE, (byte) 0x03, (byte) 0x80, (byte) 0x01, (byte) 0x04, (byte) 0x00 }); // Read PACS 5023

It returns this:

9E020003
// I need 000000310BC53938

Any help is appreciated since I am new to smart card development. Thanks in advance.


Solution

  • I was able to use javax.smartcardio, and get the Wiegand data using code like below. At the end you can see the facility code and card number are printed.

    TerminalFactory terminalFactory = TerminalFactory.getDefault();
    
    CardTerminals cardTerminals = terminalFactory.terminals();
    
    List<CardTerminal> terminalList = cardTerminals.list();
    
    CardTerminal cardTerminal = terminalList.get(0);
    cardTerminal.waitForCardPresent(10 * 1000); // wait 10 seconds
    Card card = cardTerminal.connect("*");
    System.out.println("Card: " + card);
    CardChannel channel = card.getBasicChannel();
    
    byte[] aid = { (byte) 0xA0, (byte) 0x05, (byte) 0xA1, (byte) 0x03, (byte) 0x80, (byte) 0x01, (byte) 0x04 };
    CommandAPDU apdu = new CommandAPDU(0xFF, (byte) 112, (byte) 7, (byte) 107, aid, 256);
    ResponseAPDU r = channel.transmit(apdu);
    byte[] bytesOut = r.getBytes();
    
    int num1 = (int) bytesOut[3];
    if (bytesOut.length - 6 != num1)
    System.out.println("problem");
    
    int numberOfBitsShifted = (int) bytesOut[4];
    int num2 = num1 - 1;
    
    byte[] newBytesArr = Arrays.copyOfRange(bytesOut, 5, 5 + num2);
    if (newBytesArr.length != num2)
        System.out.println("problem");
    
    ByteBuffer wrapped = ByteBuffer.wrap(newBytesArr);
    int num = wrapped.getInt();
    int first26 = num >> 6;
    int withoutParity = first26 >> 1;
    
    int cardNumber = withoutParity & 0xffff;
    int facilityCode = (withoutParity >> 16) & 0xff;
    
    System.out.println(facilityCode);
    System.out.println(cardNumber);
