road toll

The increasing costs for construction and maintenance of road infrastructure, the necessity of traffic routing and the need of new sources of income for public authorities are the main driving factors for expansion of existing and development of new road toll systems. Especially inner city toll and heavy traffic tolling are emerging segments within this market.

In order to fulfil the two main requirements within such systems – performance and security – the system provider intensively look for encapsulated security components to be used in on- board-units (OBU) as well as in the road side equipment. United Access is focused on the development of such security modules (SAMs) with dedicated operating systems serving the very special functional requirements and high performance needs. All our in-house developments within this special segment are based on certified smart card security controllers from Infineon or NXP.
