Just wondering whether people agree that the need to move a phone camera over a printed or on-screen QR code to instantiate an app and start using the instance is a case covered by 2.5.4 Motion Actuation? I would argue that an alternative (such as a text field for the onput of the numeric equivalent) would be required to pass 2.5.4. (This is an native app case, but arguably the same could apply to a web app.) Any thoughts?
