Can the ETC device be used without sticking it?

[VanCorey]

It is possible to use the ETC device without sticking it to the windshield. As long as the induction device at the highway toll station can detect the ETC device, it can be placed on the car's dashboard or held up manually when passing through the toll station. ETC (Electronic Toll Collection) is an electronic toll system. When a vehicle equipped with an ETC device passes through a toll station, the induction device at the toll station detects the ETC device on the vehicle, automatically matches the information, and completes the deduction and release process. ETC Working Principle: Through the on-board electronic tag installed on the vehicle's windshield, dedicated short-range communication is established with the microwave antenna in the ETC lane at the toll station. Computer networking technology is used for backend settlement processing with the bank, enabling vehicles to pass through highway or bridge toll stations without stopping while still paying the toll. ETC Billing Principle: The toll amount for ETC vehicles is rounded according to the "round down if less than 0.5, no change if 0.5 or more" rule (i.e., amounts with a decimal less than 0.5 are rounded down, while those with a decimal of 0.5 or more remain unchanged). After a 5% discount, the amount is then rounded to the nearest cent. MTC vehicles still follow the "round to the nearest yuan" rule. All of this is based on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and emissions and minimizing pollution; Reduced wear and tear: Saves costs by reducing the frequency of vehicle starts and stops, lowering wear and fuel consumption; Improved efficiency: Theoretically, ETC lanes can process vehicles 2-3 times faster, making traditional ETC more advanced, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, intercity transportation smart cards should be widely implemented in key city clusters, and the proportion of vehicles equipped with ETC should significantly increase." It also set a target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles should reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and increasing the adoption rate among passenger vehicles, efforts will also be made to promote ETC usage among trucks and explore deeper integration of the ETC system with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation developments. This will provide car owners with comprehensive travel services, meaning more application scenarios will support ETC usage.
