title: Read qrcode from a web page with camera.
body: <p>Im looking for a solution to read a QRCode on a webpage.</p>
  
  <p>Lets say I've generated with PHP and some library (zxing or something else) a QRCode and its printed on a piece of paper, ok?</p>
  
  <p>What i would like to do now, is to read it back with tablet/smartphone throught a web-page.
  I browse to that page, it asks me to aim the QRCode with the camera, and then the scanned content is sent back to the page that decodes it.</p>
  
  <p>There's something out there to handle this without the need to use an Android/iOS app?
  It could be another type of 2D barcode aswell, not exclusively a QRCode.</p>
