• If you use QR codes, please ensure that the information that is accessible via the codes is included in the app that is downloadable (or alternatively can even be blue-toothed to you on the day) or alternatively provide free wi-fi access (perhaps for a limited time - 2 hours say) otherwise. Heavy downloading over WAP can make for nasty surprises when the phone bill comes in. I don't mind so much paying (a small amount) for an app, but if I have to pay for the data to access it, then maybe not.
