Dear people who have recently discovered QR codes,

QR codes can be very useful. They are particularly useful when they are printed out and stuck around the place. Or even on a slide on a presentation so people can access the info on their personal device.

QR codes are NOT useful on a social media post or a website that people access on their own device because if you are looking at it on your phone you cannot scan it with your phone. Just post the bloody link!

@urbanfoxe @simon QR codes can also cause accessibility problems for some people who don’t see that they exist, or make it more difficult for some blind people to scan them even if they know, more or less, where they exist.
