How does the parking attendant know I've paid?

EasyPark sends a signal to the parking operator's database. In most areas, the parking attendant scans your license plate. When they do, they receive a signal from their database to check whether you have paid for your parking.

Some areas require a handwritten note ("I park using an app") or a sticker behind your windshield. Should this be the case, the EasyPark app will notify you automatically.
