The post-pay procedure is very easy and convenient: the viaBOX must be collected at a Distribution Point in Poland. Tolls are subsequently settled via UTA. Toll transactions invoiced will, as usual, be shown as an individual item in your UTA invoicing documents.
The pre-pay procedure is an account in credit, and the viaBOX must be collected at a Distribution Point in Poland, where it can be topped up with an individual amount (minimum amount: 120 PLN, approx. 30 Euro), which then can be spent on tolls little by little.
In both cases, the Polish toll company viaTOLL requests a deposit in the amount of approx. 30 Euro (120 PLN) per viaBOX registered which can be settled via UTA.
