How to Check if the ETC Card is Working Properly?

[SanLena]

Methods to check if the ETC is functioning normally: Manually insert and remove the card. If there is a sound, it indicates that the ETC is in normal working condition. How ETC Works: Through the dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, the computer network technology is used to conduct background settlement processing with the bank. This achieves the purpose of vehicles passing through highway or bridge toll stations without stopping while still paying the toll. Where ETC Can Be Installed: For small vehicles such as cars and vans, the OBU device is installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part. ETC Installation Position Requirements: The height should not be less than 1.2 meters or more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane).
