Exiting is possible by scanning the QR code and, alternatively, by number plate recognition, if you have specified the number plate of your vehicle when booking. The indication of the number plate is purely optional and not mandatory. By QR code: The booking confirmation contains a QR code. You scan this at the exit using the scanner in the exit column to open the barrier. The ideal distance between the scanner and the QR code is about 5 cm. By number plate: The number plate of your vehicle will be read at the exit when you drive up. The barrier then opens automatically with the correct data, without the QR code of your booking confirmation. Note: Exiting by number plate recognition only works if the number plate was also specified at the time of booking.
