How to Fix ETC Malfunction?

[MacBella]

You can first check if the OBU fixed on the car's front windshield has fallen off. If it falls off, the anti-tamper button on the back of the OBU will reset, and you will need to go to the ETC card service point for reactivation. Below is a detailed introduction about ETC: 1. Introduction: ETC is the Electronic Toll Collection system, which is an automatic toll collection for highways or bridges. Through dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, it uses computer networking technology for backend settlement processing with banks, thereby achieving the purpose of vehicles passing through highway or bridge toll stations without stopping to pay tolls. 2. Technology: The ETC system uses automatic vehicle identification technology to complete wireless data communication between the vehicle and the toll station, enabling automatic vehicle sensing identification and the exchange of related toll data. It uses computer networks to process toll data, achieving a fully automatic electronic toll collection system without the need for stopping or setting up toll booths.
