Firstly the problem. This is a great app for either your mobile phone or tablet, but if you have a low data usage plan it will rapidly eat up your allowance.
However, if you have access to Wi-Fi network that problem is solved!
Basically any image can be given an 'Aura' and when it is scanned by a mobile device extra information is displayed on screen. This 'Aura' works in much the same way as a QR code does, but the result is not limited to just web sites.
There are already many examples of this in everyday life, and many similar bespoke versions of very similar software. Many Sunday newspapers now offer extra content that is triggered in the same way, offering their readers access to 'exclusive' information.
I shall experiment with this when I have access to a Wi Fi zone and report back later
