ETCS Fee Collecting Process

When a car with a High-Pass card installed in the OBU passes through the tollbooth with the High-Pass system, the antenna on Gantry1 recognizes the OBU and classifies the vehicles. Then it automatically collects the fee from the High-Pass card. When the vehicle passes Gantry 2, it confirms whether the fee has been paid and indicates the remaining amount on the left of the screen for the driver to view.
