title: How to read NFC tags with ACR122U?
body: <p>I have a ACR122U NFC reader. I have found an <a href="http://ludovicrousseau.blogspot.nl/2010/04/pcsc-sample-in-c.html" rel="nofollow">example</a> how to access this with pcsc-lite (under Ubuntu). I can access the reader, but I have no luck reading any information from a tag. When I read information from the tag I get no response. I think it has to do with the command I send in the SCardTransmit call. But I have no idea what kind of APDU command I have to send to the tag to get a correct response. </p>
  
  <p>Anybody done this before?</p>
