Re: QR Codes are still around....
And there's the problem, right there. QR codes in the west have only ever really been used for advertising. We've become accustomed to seeing it as an invitation to "scan this if you want to see more ads".
Not very surprisingly, not a lot of people take up that invitation.
We've always seen it as a machine-optically-readable version of a URL. But it really doesn't have to be. It can convey (exchange) all sorts of information that's got nothing to do with web browsing, and it sounds as if the Chinese have realised this. Good on them.
