Go to Asia and you can see QR codes everywhere. Payments mostly, but in Singapore you will find it also for checking in and out of places for COVID-19 contact tracing and everyone uses it (although now Bluetooth/ tap your phone is taking over).

I use it for guests wanting my wifi - just scan this QR and you’re in without much fuss.

QR track and trace is also used here in the UK, quite effective in my opinion although with lockdown being lifted the app will be scrapped.

It may be effective, but it is yet another way we lose privacy.

Also fashion magazines in Asia, QR code next to teen clothing. Probably can order straight from there and the magazine gets a cut.

also QR code for contact information sharing is big in Asia, kind of like a handy digital business card
