Needs image stabilization

The app works OK on my computer (Mac Pro, 10.6.8) but has a basic flaw shared by similar apps. While its not too hard to hold a smartphone steady while scanning a QRcode, its quite another story when the camera is attached to your computer and you have to hold the page on which the QRcode is printed. The problem seems to be that that the software is trying to scan the QRcode and decode it in real time. Any significant movement of the target while the scanning/decoding is taking place causes errors that prevent correct code recognition.

It might work a lot better if the app took "snapshots" of the QRcode at regular intervals so that it could perform its scan and decode on a steady image.
