title: APDU ISO 14443 Type B Authentification
body: <p>I have an ACR122U Reader and a command line tool to send and receive APDU commands. 
  My Card uses ISO 14443 Type B.
  ATR is 3B 80 80 01 01, T=CL, ATS = 05 77 77 81 02.</p>
  
  <p>Auth Key is 6bytes of FF</p>
  
  <p>How can i load the Auth Keys in memory and auth. to blocks?</p>
  
  <p>Am now for days in google, tried many APDU commands. 
  Thanks for your help!</p>
