Can the OBU be replaced with a different card?
1 Answers
OBU cannot be replaced with a different card. The card used when applying for ETC is a dedicated card, which is bound to the license plate number, ID number, and engine number. If it is replaced arbitrarily, it will become unusable. The OBU is the device installed on the front windshield of the car where the credit card is inserted. OBU and ETC are two completely different concepts. ETC is the electronic toll collection system for highways, while OBU is the on-board electronic tag. When a vehicle passes through a toll station, the OBU responds, and the computer toll management system deducts the corresponding toll from the vehicle's prepaid account or sends instructions to other auxiliary facilities to operate.
