title: Error 6 when connecting Gemalto smart card
body: <p>I am new to smart card development. What I am trying to do is, 
  <br>1>get the name of the card reader.
  <br>2>connect to the card in the card reader.
  <br>3>change the admin key of the card using c# .</p>
  
  <p>for the first point i used winscard.DLL- function SCardListReaders. It worked well.
  <br>now for next step, I tried with function -SCardConnect of winscard.dll.</p>
  
  <p>but when ever i am running this , it returns "6", but it should return 0. I am really confused.
  <br>Any idea, what that means? where i am doing wrong?
  <br>Please help.
  <br>Thank you in advance.   </p>
