I don't know what's going on. I did the same thing you did and got one that cost two bucks. You can see my setup. Are you on Mavericks? I'm still on Mountain Lion 10.8.5 and iOS 7.1.2 Would that make a difference?

The full title I get is: Scan - QR Code and Barcode Reader. The seller is QR CodeCity, LLC. It works really well, but I'm mystified why we're getting different results with the same input to the same location.
