title: Mifare ultraligtht and APDU commands
body: <p>I am looking for a list over various APDU commands, supported by the mifare ultralight cards,
  I have tried to search for how to lock bytes, making them permanently readonly, but so far unable to find anything, is it even possible to set any of these blocks to readonly, or is there even a permanently reset card to 0 ?</p>
  
  <p>thanks again</p>
