Can ETC still be used after it falls off and is reinstalled?

[McAndres]

No, it cannot be used. The ETC device will become invalid if it is removed by yourself, as the ETC device has an anti-tamper function. There is a small switch behind the ETC electronic tag. Once it is peeled off from the windshield, the internal switch will automatically close. Therefore, you must take the vehicle's registration certificate to the ETC service provider for reactivation. 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 settle accounts with the bank in the background, achieving the purpose of paying road and bridge tolls without stopping at the toll station. All of this is based on the principle of passing first and deducting fees later. Benefits of Installing ETC: Saves time: Eliminates the hassle of waiting in line; Green and environmentally friendly: Green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Saves wear and tear: Reduces costs, decreases the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improves efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC more updated, 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 intercommunication of transportation smart cards in key city clusters will be basically realized, and the proportion of vehicles equipped with ETC will be significantly increased," and explicitly proposed in the main indicators of the "13th Five-Year" comprehensive transportation development 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 ETC usage rate of passenger vehicles, the future will also promote the use of ETC for trucks and 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, providing comprehensive travel services for car owners. This means that more application scenarios will support ETC applications. Precautions for Installing ETC: Do not block the view. It is best to install it behind the rearview mirror: Many car models have a large rearward tilt angle of the windshield, resulting in a smaller driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spots. Install it behind the rearview mirror on the right side to avoid blocking the view. Do not affect charging: The ETC electronic tag consumes power, but generally does not need to be charged or have its battery replaced because there is a solar panel on its back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and do not place it where the solar panel is easily blocked. Once installed, do not remove it casually: The button in the middle of the adhesive is an anti-tamper guide rod, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-tamper guide rod in. If it is removed casually, the anti-tamper guide rod will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. Precautions for Using ETC: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatically sensing and paying for the vehicle in front. The recognition speed for ETC lane passage is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, resulting in a deduction failure. When using a debit card to bind ETC, insufficient balance will also cause a deduction failure.
