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 hate that so much. Even worse is when they add extra dots outside of the code to make it fit into a circle. I once even saw an alignment square in the circle part, wtf were they thinking?
I mean you could also increase the error correction rate without increasing the company logo size.
