QR code reading does not depend on the orientation, at-least as per its spec. there are many apps and devices out there that can read a QR code in any orientation.
In the app that is used by me, the brightness of the screen is automatically increased by the app as soon as I open the ticket QR, and then reduces to its previous state, once the QR code display is removed.
- lxgr 2y agoNot any orientation – if you present a QR code ticket the wrong way around, or even just angled away from the plane the reader focuses on too much, it doesn't work. Contactless tickets work both ways, and in addition to that usually have a larger, more forgiving "landing area". On top of that, they can usually read through a wallet (but that's more relevant to regular commuters, arguably; tourists and infrequent riders will likely have purchased the ticket just moments before using it).
