Several different system concepts for freeflow electronic toll collection exist, two of which have been the subject of intense discussions. The first is a system based on GSM and Global Positioning System (GPS) in the 900MHz band, the second employs a short-range microwave link (5.8GHz band) between a beacon and the car itself. The main emphasis of this paper is lying on the system components and security modules developed by ORGA Card Systems.
