title: What's the difference between DESFire and DESFire EV1 cards?
body: <p>I have a contactless card and I know it is a MIFARE card. I have no document and no authentication key. After a reset, I received the following ATS:</p>
  
  <pre>
  
  myubuntu@lol-MS-7693:~$ nfc-list 
  nfc-list uses libnfc 1.7.1
  NFC device: ACS / ACR122U PICC Interface opened
  1 ISO14443A passive target(s) found:

  <p>After searching above ATS in google, I found the following info <a href="http://nfc-tools.org/index.php?title=ISO14443A" rel="nofollow">here</a>:</p>

  <p>So, my card is either a DESFire card or a DESFire EV1 card. The question is, how can I detect which of the two my card is precisely?</p>
