I literally just scanned a couple while at the doctors - one to check in, and another provided a url of a form to fill in. They're also in some restaurants where you can get to a menu to order from your phone. You also scan QR codes for use in two factor authentication apps. Covid has normalised QR code scanning in Australia - we have to do it at certain venues in order to show our vaccine passes.
