I find it amazing that as apparently intelligent human beings we have to complicate the way we do things when there's a proven system already in place.
We seem to have a fascination with apps.
Agree 100%. RFID fob is so much more dependable than apps, so I always buy/set it up. I've had apps and phones let me down so many times.
Seldom used but mission critical charging app that requires updating EVERYTIME you want to use it. Then taking an age to update and then re-entry of credentials that you probably forgot.
Data not working.
Phone updating.
Phone flat & charging cable not in car.
QR code not working cos faded/scratched/too bright/too dark/raining/graffiti.
Charger lost its data connection to the app system (well that one helped since it still accepted fob's when no-one else in the que had one).
