Should the Telepass device not work at the exit, you will need to go to the car park's infopoint offices and pay the amount due there, asking the employee to cancel the incoming transit done with Telepass.
The Telepass Parking service does not have any additional cost.
You can conveniently pay for parking in one of the participating garages right with the Telepass device.
Entering or exiting the participating garages of airports, stations, and fairs, look for the column with the Telepass logo, the gate will automatically lift and you will be able to leave without stopping at the cash desk.
You can view the amount charged for the stop on the parking meter display when exiting the parking garage. In any case, the list of the stops you made and the relative amounts charged are always available on the Reserved Area of the website.
If you disactivate the Parking service on the website Reserved Area, you won't be able to pay for your stop in the participating parking garages through the Telepass device. Moreover, also the Ferries service will be disactivated.
