I need to be able to read the unique id of the following card types: mifare , emv and calypso.

i m able to read the ATR of those cards , but could not find the command for receiving the unique id 

Card card = terminal.connect("T=1");
CardChannel channel = card.getBasicChannel();
ATR r2 = channel.getCard().getATR();
byte atr[] = r2.getBytes();

    At least a [related question](https://stackoverflow.com/q/39609445/1435475). I'll vote for close however, since the question seems too broad and I can't recognize a real attempt to solve it - the ATR is definitely far from unique. – guidot Jun 10 '19 at 15:39

It seems like the answer to all the specified cards is 0xFFCA000000 (UID)
