The sudden beeping and flashing green light of the in-car ETC card is due to these gantries. Their function is to read the corresponding vehicle information when a vehicle equipped with an ETC electronic tag passes by, and then use computer networking technology to perform background settlement processing with the bank. Relevant information about ETC is as follows: 1. Introduction: ETC is an electronic toll collection system for highways or bridges that allows for automatic payment without stopping. 2. Working Principle: The working principle of ETC involves dedicated short-range communication between the on-board ETC electronic tag installed on the vehicle and the ETC microwave antenna on the toll station lane.
