Terence. Interested to read your thoughts on QR code hijacking. We are developing a very public facing QR (and NFC) application, and the hijacking aspect worries me - so I have trying to think of ways to make the scammers' attempts harder to implement - for example, holographic QR codes, codes with background colours/images, as well as telling users this will redirect them to a specific URL (although we will be redirecting from there, which may complicate things!). But I am struggling to think of anything else.....
