For those who don’t know, it’s where someone takes a QR code like on a poster for a concert and puts a sticker with a different QR code on top to a fake website that looks like the concert website (or a Rick Roll).
The obvious answer is to scratch off the QR code if you notice it’s a sticker, but It’s not always acceptable -or legal- to start damaging stuff to check if it’s real or not. Also what if it’s out of reach on a sign or something?
You can’t put a little text under saying what the website is as a sort of checksum because the vandal can just write their own website under their sticker.
Unfortunately sometimes it’s really hard to avoid. I’ve been to restaurants that don’t even have physical menus. You could probably find a menu on their website, but not always.
“Hi, I’d like a menu”
“Oh, our resteraunt only has QR codes.”
“Ok, bye bye.”
