Generally, when a vehicle with ETC equipment passes through a toll station, the vehicle-mounted equipment will realize vehicle identification and information writing, and automatically deduct the corresponding funds from the pre-bound IC card or bank account, so as to realize rapid opening to traffic, which is especially suitable for use in expressway or the bridge and tunnel environment with heavy traffic.

Etc is a non-stop electronic toll collection system, which communicates with the microwave antenna on etc lane through the electronic tag installed on the car, and completes the settlement by networking with the bank through the computer, so that the toll can be easily paid without stopping.
