I’ve always found them to be kinda cool, but, like… I can type in a url faster than getting out a camera and getting it to scan most of the time. Especially when they’re using a shortener to have a URL that’s literally just 4 characters long. So I pretty much never actually do anything with QR codes.
They can be used for more than just a website, but I’ve never seen one that does anything but act as a link. Can’t you fit, like, a small image in one? Rickroll someone with just Astley’s face instead of going to the YouTube link?
