title: Library for reading QR Codes using a Webcam
body: <p>I am looking for an open-source library that can read QR Codes using a laptop's integrated webcam.</p>
  
  <p>Preferably, the library should be written in C#, but Java would be good as well. It should be able to run on a Windows 7 64-bit platform.</p>
  
  <p>It is important that I have access to the decoded string, i.e. I don't want an application that opens up a URL in a browser. I have looked around and found libraries which either read the codes from image files, or use the webcam for input but do not allow access to the string. I haven't managed to find one which does quite what I want. Any pointers would be appreciated.</p>
  
  <p>Thank you for your help and suggestions.</p>
