I am SHOCKED that QR Codes actually happened. I would have *never* bet on this ridiculous tech, but as soon as all phones built it into the camera app, then restaurants decided that a QR code pointing to a freaking PDF in Dropbox was a valid menu, it was over. The avalanche had begun, and it was too late for the pebbles to vote.
@shanselman I do hope we can one day move to NFC tags instead of QR, but I often see both combined anyway so I'm pretty happy.
Unfortunately no matter the access solution, "PDF on Dropbox" is very much an indicator of general tech know-how.
