I use them for our printed version of our documentation, each document has a cover page with a QR code pointing to the latest version of the electronic copy.
Handy during an outage, and you don't have to search for the online copy.
Smart! If my company ever digitises enough to make this a possibility, I'll implement (or at least suggest) it!
Who has time to hate things like QR codes?
Redditors maybe?
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?
Agreed. Often typing out URL is just faster, but it depends on the URL. Also it depends on the situation and how good you are at it. In example to use the camera, I just hit one app and hold it to scan in a second. Compare this to click browser app, new tab, click url area and start typing. Maybe you make a typo or you did not, but read carefully three times so you don't land on a wrong site. Maybe its cold days and you don't like typing right now. Also helpful for people who have difficulties in typing for whatever reason. But if you were already holding the phone with the browser, then its less of a deal.
Also there is this surprise effect (as you already mentioned), which makes people curious too. It has error correction as well. So if there is a missing dot in the "i", then you don't need to try lowercase L or whatever.
Scammers love them too
