title: iOS: Real Time OCR on top of live camera feed (similar to iTunes Redeem Gift Card)
body: <p>Is there a way to accomplish something similar to what the iTunes and App Store Apps do when you redeem a Gift Card using the device camera, recognizing a short string of characters in real time on top of the live camera feed?</p>

  <p>I know that in iOS 7 there is now the <code>AVMetadataMachineReadableCodeObject</code> class which, AFAIK, only represents barcodes. I'm more interested in detecting and reading the contents of a short string. Is this possible using publicly available API methods, or some other third party SDK that you might know of?</p>
  
  <p>There is also a video of the process in action:</p>
