What are the reasons for the failure of the ETC tag?

[Jean]

ETC tag failure can be attributed to the following reasons: 1. ETC is designed for specific vehicles and has a protective linkage during installation. There is a push-button switch on the side that adheres to the car's windshield. If this switch is triggered twice consecutively, it will cause the ETC electronic tag to fail. 2. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag becomes detached or loose, may also lead to the failure of the ETC electronic tag. ETC stands for Electronic Toll Collection, which is an automatic toll system for highways or bridges. It utilizes dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at toll stations. Through computer networking technology, it processes background settlements with banks, enabling vehicles to pass through highway or bridge toll stations without stopping to pay the tolls.
