@Frantasaur @JoBlakely tbh. QR codes are not more of a risk than a printed URL. They have been used in demonstrations to scare people, but I would classify these demonstrations itself almost as a scam. They usually are based on the implicit assumption, that it would be more secure to copy the URL by hand, which it isn't. Do not rely on recognising phishy URLs to be safe online!
TL;DR QR codes are fine; don't trust any website you got from a flyer blindly.

Most people are unlikely to type in Cyrillic characters (as one example) when hand typing or using voice transcription to input a URL, but could easily mistake those when a phishy URL shows up when they scan the QR code.
QRs remove friction at a time when people really need friction removed, like when being tired, stressed or in a hurry, making it even less likely that someone would catch a scam URL. I think they're dangerous for general use.
