What does it mean to install etc in a car?

The etc installed on the vehicle refers to the fully automatic electronic toll collection system. Details are as follows: 1. Automatic Electronic Toll Collection System (ETC) is one of the service functions of Intelligent Transportation System, which is especially suitable for expressway or bridge and tunnel environment with heavy traffic. At present, there is a special ETC toll collection channel at the expressway toll collection office. As long as the owner installs the sensor card on the front windshield of the vehicle and pre-stores the fee, when passing through the toll station, the owner can automatically deduct the high-speed toll from the card without manual payment or parking, thus realizing automatic charging. 2. The system needs to install a vehicle-mounted device carrying vehicle information on the vehicle. When the vehicle enters the entrance of the non-stop electronic toll collection channel, the station-level equipment of the expressway data acquisition and processing system reads the vehicle information in the vehicle-mounted equipment, calls out the matched vehicle data from the database, releases the vehicle data, stores the records and uploads them to the data management center of the expressway data acquisition and processing system. The data management center analyzes the facts of the deduction transaction formed by passing vehicles, uploads them to the bank, and sends them back to the data management center in real time after completing the transaction processing.
