I think QR codes are cool because it’s literal computer data in ink. You can draw a QR code with a pencil if you know how to encode the data. It’s like a punch card, a physical manifestation of digital data.
However using a QR code is really freaking annoying, especially if you have a cheaper phone. I always configure my phone to only show the encoded string and not click the links because fuck normalizing blindly clicking links
I used one of those promos to get a bunch of free stickers made and I did a QR code to lemon party with my friend’s Instagram at the bottom. I travel a lot for work so I was going to post them up everywhere. Unfortunately I got them printed in yellow which made the QR code not work.
I find them really fascinating, especially their error-correcting, but I do find them weird occupying every banner without any alternative and trashing our human world with too much of them, outside of the discussion of them being too much needed for functioning in our society.
