You can save them in the app and not have to scan every time too. It's pretty common at people's regular lunch places for them to pay while they wait in line. There's no deep technical reason this couldn't be implemented with the card system either, of course.
- luckylion 6y agoHow does the shop know who paid? Do they then check your phone screen for the correct verification code that matches their transaction?
