Hello,
I find QR codes extremely annoying, so that is one reason why I don't use
Whatsapp.
They are accessible if I can trust when I point my phone to the screen, I
get the QR code.
I have had dialogues warning me of updates block the QR code though and I
had no idea. Apparently some brilliant person thought it would be a good
idea to make dialogues that are always visible, but don't trap focus as
well, so I could have a dialogue telling me something that is blocking my
screen, but I would have no idea.
Other times QR codes would be a problem is when accessing the site on a
device without a screen. Most Braille notetakers don't have a screen.
Also accessing the site on a mobile device is a problem, because I don't
know how to point my phone's camera at it's own screen.
If users don't have their phone, or their phone is dead, or they don't have
Wi-Fi with their phone, they couldn't use the site.
If there is an alternative that doesn't require the phone along with the QR
code, I think you'll be fine.
Thanks,
