If the license plate number bound to the ETC does not match the actual license plate number, it cannot be used for passage. Different vehicle types incur different highway toll fees. According to the "Rules for Using the Non-Stop Rapid Passage System," when applying for an ETC, the ETC card and OBU device are already bound to the vehicle, and the vehicle's relevant information is imported, forming a one-to-one correspondence. If you change to a new vehicle with a new license plate, you need to cancel the original ETC and reapply for the new vehicle. If it's a new vehicle with an old license plate, simply update the vehicle information at an offline service center. ETC is an electronic toll collection system that does not require stopping. ETC lanes are designated for vehicles equipped with ETC onboard devices, utilizing electronic toll collection. The electronic toll collection system is an automatic toll system for highways or bridges. ETC Deduction Principles: Highways will have one or more ETC lanes. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology for backend settlement with banks, the system achieves the purpose of vehicles paying tolls without stopping at highway or bridge toll stations. All of this operates on the principle of passing first and deducting fees 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 exhaust emissions, thereby minimizing pollution; Reduced wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption; Improved efficiency: Theoretically, ETC lanes can increase vehicle passage efficiency by 2-3 times, making traditional ETC updates faster, newer, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More Support: The State Council explicitly 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 clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a clear target in the main indicators of comprehensive transportation development during the "13th Five-Year Plan" period: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More Future Possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC adoption rate for passenger vehicles, efforts will be made to promote ETC usage for trucks in the future. There will also be exploration into the deep integration of the ETC system with transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications. ETC Usage Precautions: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, to prevent the preceding vehicle's ETC device from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters to avoid automatic sensing and paying for the preceding vehicle. The recognized speed for ETC lane passage is 20 km/h. If the speed is too fast, the vehicle's device information cannot be read, leading to failed toll deductions. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will render the electronic tag invalid. It can be taken to the bank where the ETC card was issued or the highway service office for inspection. If the detachment or loosening is not due to human factors, reactivation is sufficient. When using a debit card bound to ETC, insufficient balance will also result in failed toll deductions. Follow the guidance of on-site staff to proceed to a manual MTC lane and use cash or card payment for passage. Excessively thick car windshields can cause poor sensing. This is particularly important for vehicles that have had their windshields replaced after accidents or for those who have modified their front windshields.

I heard this from a traffic police officer at the service area last time - never stick a found ETC device onto your own car. These things are linked to license plates and bank cards. When the toll gate cameras scan it and find a mismatch between the license plate and ETC information, they'll immediately alert the authorities. I've seen drivers using picked-up ETC devices on highways getting stopped and fined 500 yuan, with the original owner's bank account being charged too, eventually leading to police involvement for theft. If you really can't find the owner, hand it over to highway toll stations or banks - they can check the device serial number to contact the vehicle owner. By the way, dismantling the ETC yourself might trigger its anti-tamper lock, making it unusable even for the original owner.

A friend who works at an ETC company mentioned that every device is preloaded with license plate, vehicle model, and owner's ID information when it leaves the factory. Even if you forcefully stick it on the windshield, the system will automatically verify the license plate captured by the camera against the device information when passing through the highway. If any discrepancy is detected, the card will be immediately locked. Last year, I helped a neighbor deal with a similar situation—he picked up an ETC and tried it three times without success, which instead caused the original owner's card to be frozen and replaced. The new devices now even come with GPS tracking, making it easy for the owner to locate the usage position after reporting to the police.

The recognition system at highway toll stations is far smarter than imagined. The OBU chip inside the ETC device stores a unique code, and the RSU antenna at the toll station not only reads the card but also verifies vehicle characteristics. I once disassembled an ETC from a scrapped car and found it contained a gravity sensor—removing it would trigger a mechanism. Even if a found device isn't locked, the toll would still be deducted from the original owner's account, and they could spot the anomaly by checking their statement. If the device is linked to a credit card, it might even involve risks of fraudulent transactions.

During a self-driving trip, I once saw a guy struggling with a found ETC device at the toll booth, but the barrier just wouldn't lift. The staff explained that the device was registered to a blue-plated passenger car, while his vehicle was a yellow-plated truck. The usage permissions for different vehicle types are completely different, and truck ETCs require a separate application. Moreover, the stored-value cards or cards in the device are all under real-name registration, and the license plate can be traced for liability if caught on camera. It was suggested to post a lost-and-found notice at the location where it was found or call 95022 to contact ETC customer service.

The repair shop technician told me that the ETC device has a physical binding mechanism. There's an anti-tamper switch hidden beneath the solar panel on the back – if you peel it off the windshield, it automatically locks. Nowadays, new devices are even connected to the vehicle's OBD port for real-time verification, making it impossible to read signals from non-original vehicles. Once when I was helping a customer with an ETC malfunction, I found that devices tampered with privately wouldn't even be serviced at authorized repair points. If you really want to return it but can't find the owner, you can note the serial number on the device surface and call the issuer to report it.
