title: How to work with a Smart Card
body: <p><strong>My project</strong>
  I am working on a small program which has to set an alarm  if the user locks the computer without removing the Smart Card from the computer. </p>
  
  <p>I am using C# with WPF and .Net 4.0 and my smartcard is version V4.2C</p>
  
  <p><strong>My problem</strong>
  I have all the functionality to work but I simply don't know how to detect if the Smart Card is in the Smart Card Reader. </p>
  
  <p>I have tried to search on google but with no result so I hope some of you can help me.</p>
