Abstract
An apparatus has a detector for, when the operation of a vehicle is started, determining whether a specific portable wireless tolling storage medium is loaded in an automatic toll processing unit installed in the vehicle. A warning unit produces a visual or auditory warning if the detector determines that the specific tolling storage medium is not loaded. The apparatus enables realization of a tolling system that prevents incidents where a user neglects to load a tolling storage medium into a toll processing unit, thus ensuring normal toll processing.
