Even though both NFC 'info' tags and QR codes seem not to have really taken off in the mainstream after a decade of availability*, QR codes are still a 'thing' and most people recognise them when they see the four corner dots and mass of encoded characters within. And most phones can now recognise QR codes, even if - as here - an extra application is needed. There are quite a few QR code scanners under Windows 10 Mobile, but this is the first that I've seen that focusses (pun intended) more on QR code generation and what you might do with such a graphical construct.
