renzevI have the weirdest aesthetic preferences
My current bugbear with QR codes is that lots of folks have started putting their company logo in the middle of the code.
Sure it still works but it makes the error correction work harder so your users need to be nearer or have better cameras than they would otherwise. Annoying.
I mean you could also increase the error correction rate without increasing the company logo size.
I walked by a physical storefront a few weeks back. Instead of posting their hours on a door, they had a sign with a QR code to scan. How absurd.
