The only people i see running around suggesting this is a better method is Image Recognition Vendors and ‘Artistic Directors’ who think QR codes are ugly and wont deign to put them into their glossy magazine (someone needs to take that art director out to the woodshed and tell him that his role is to sell magazines and not make ‘art’).

QR codes (and other 2d codes) have a clearly defined and understood interaction process.

Image recognition requires an always on internet and third party servers being available (eg. you are caught in their trap forever).

Realistically there’s no need for it, go solve world peace or something useful as Denso solved 2d bar code problem over 14 years ago.
