>Often when you see a QR code they will print the url below. But there is nothing telling you that the QR code is corresponding to the text, for the casual user, a tricky QR code with an URL printed below could be even more deceiving, I mean, say you know the possible issue, manually type the printed URL that seems legit and it is actually legit, someone queueing behind you scans the QR code and bam, he/she gets the "bad" site instead. (I am thinking, there was a post some time ago about parking lots where paying for the parking was through QR codes that were replaced by "bad" ones).
