Reinserting the card will allow it to work. According to the "Rules for Using the Non-Stop Rapid Passage System," the ETC card must be inserted into the OBU device for normal operation; otherwise, user information cannot be read. If the card is removed, you can use the manual lane and have the staff swipe the card. When inserting the ETC card into the OBU device, a prompt sound will indicate that the device is activated. Without the card inserted, the device remains in a dormant state and cannot recognize vehicle information at toll stations. Therefore, removing the card disables ETC functionality, but it can be reinserted when needed. ETC is the Electronic Toll Collection system, also known as the Automatic Road Toll System. It is a specialized road toll method typically used on highways, toll bridges or tunnels, and certain urban road sections to alleviate traffic congestion. ETC Deduction Principle: Highways have one or more ETC lanes. Communication between the vehicle's windshield-mounted electronic tag and the microwave antenna in the ETC lane enables backend settlement via computer networking with banks, allowing vehicles to pass toll stations without stopping. This operates on a "pass first, deduct later" principle. Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Reduces noise and exhaust emissions by avoiding idling at toll stations; Cost-saving: Minimizes vehicle wear and fuel consumption by reducing frequent starts and stops; Efficiency: ETC lanes can theoretically improve traffic flow by 2-3 times, making traditional ETC faster and more high-tech. Compared to license plate payment, ETC is more mature and advantageous. More Policy Support: The State Council's "13th Five-Year Plan for the Development of a Modern Integrated Transport System" explicitly states the goal of "achieving interoperability of transport cards in key city clusters by 2020 and significantly increasing ETC adoption rates," with a target of "50% ETC usage rate for road passenger vehicles by 2020." Future Possibilities: Beyond improving ETC convenience and adoption rates, future efforts will promote ETC use for trucks and explore deeper integration with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and smart transport solutions, offering comprehensive travel services for drivers and expanding ETC application scenarios.
