I was at a restaurant where they refused to bring a menu, but wanted you to scan a QR code which had been pasted onto the table. This was to download a menu onto your phone and you were to order from there.
The QR code label looked kind of ratty, and I did not feel comfortable scanning it into my phone. I left and went looking for another restaurant.
However, I know nothing about QR codes. How safe is it to go around scanning any or all codes when told to do so? Could this download some sort of virus or phishing program into my phone?
