ETC can only be used for one car, but one card can be bound to multiple vehicles. According to the "Rules for the Use of Non-stop Rapid Transit System", when applying for an ETC card, fill in the "ETC Business Deduction Authorization Form", and when filling in the designated payment vehicles, multiple vehicles can be entered. That is to say, there is no limit to the number of designated payment vehicles that can be bound to one ETC card. ETC is a non-stop electronic toll collection system, also known as an automatic road toll collection system. It is a road toll method specifically used for toll roads, usually seen on highways, bridges or tunnels implementing toll policies, and some sections of urban centers to alleviate urban traffic congestion. ETC Deduction Principle: There will be one or more ETC lanes on the highway. Through the dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, the computer network technology is used to conduct background settlement with the bank, achieving the purpose of vehicles not needing to stop at the road and bridge toll stations to pay the toll. All of this is based on the principle of passing first and deducting fees later. Benefits of Installing ETC: Time-saving: Eliminates the hassle of queuing and waiting; Green and environmentally friendly: Green and low-carbon, vehicles passing through toll stations without stopping can reduce noise and exhaust emissions, reducing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key urban agglomerations will be basically realized, and the proportion of vehicles equipped with ETC will be significantly increased", and clearly proposed in the "13th Five-Year" comprehensive transportation development indicators that "by 2020, the ETC usage rate of road passenger vehicles will reach 50%". More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the usage rate of ETC passenger vehicles, the future will also promote the use of ETC for trucks, explore the deep integration of the ETC system with the development direction of smart transportation such as vehicle-to-vehicle communication and vehicle-road coordination, and provide car owners with comprehensive travel services, which means that more application scenarios will support ETC applications.
