In short: I'm after a mobile solution. A user would hover their mobile phone over a section of printed page and their phone would be directed to a URL. There would be multiple images on this page. Any alternatives to using a QR code?
In long: I would like to create a few pieces of artwork on a printed A4 page. A user would look at this page and if they like a piece of artwork - they would hover their phone over it. The phone would then recognise this artwork optically and forward the user to a defined webpage. Is there any way to do this without QR codes?
Edit: Assuming that QR codes is the preferred method - could I instead build an app that could recognise the images (from multiple pages) and forward the user to the appropriate url within the app?
