As I read over the top failed QR code campaigns for 2011, one shining lesson comes through: make sure your QR code is scannable. Seems simple, but every single big campaign fail came down to the code not being easily scannable (or scannable at all). To break it down a bit more:
- Make sure the most popular scanners will register your code. Test, test, test.
- Make sure your code is posted in places where reliable internet access is common. This rules out underground locations (subway tunnels, basements), hospitals and in-flight locations (unless you're assuming everyone will want to pay for wifi access in order to enable your code).
- Make sure nothing is obscuring your code. Graffiti, mailing labels, etc.
