摘要

The method involves determining position data of a motor vehicle, received by a satellite positioning system and toll data from vehicle-specific information in an application for determining the toll data. The satellite positioning system is attached to an on-board unit. The toll data is transferred from a mobile radio module to a toll road operator, where the mobile radio module is attached to the on-board unit. The toll data and the application for the determining the toll data are stored in a storage of a subscriber identity module card of the module of an on-board unit. An independent claim is also included for an on-board unit for a motor vehicle.
