You can enter and exit the car park without collecting the ticket or passing through the pay station.
When you access the car park, your Via-T will register you and your parking time will begin. When you leave with your vehicle, your Via-T will be recognised, your parking time will end, it will be paid for and the barrier will open.
Your stay will be paid using your wallet's balance.
The payments and reservations are subject to their own tariff conditions
