title: Communication with MIFARE Plus SL3 (commands)
body: <p>I am trying to communicate with a MIFARE Plus card - I need to read / write. However, I can't find the documentation I need to do this. I understand that the command set is under NDA (or something), but my company has access to the documents - I just don't know which ones I need to request from them.</p>
  
  <p>Any help would be greatly appreciated.</p>
  
  <p>In case anybody provides a really technical and detailed answer (fingers crossed), I am doing this on Android</p>
