What does highway ETC refer to?

Highway ETC (Electronic Toll Collection) translates to electronic toll collection, which is a non-stop toll collection system. On highways, there will be one or more ETC lanes. The ETC charging method: through the microwave-specific short-range communication between the on-board RFID tag installed on the vehicle's windshield and the microwave antenna on the ETC lane of the toll station, using software networking technology to conduct background settlement processing with the bank, thereby achieving the purpose of vehicles passing through the toll station without stopping to pay the toll. Banks install this type of ETC express card with the principle of 'pass first, pay later'. ETC application conditions are as follows: Provide the original and photocopy of the vehicle owner's valid ID card and vehicle license. The photocopy of the driving license needs to include the page with the most recent annual inspection stamp; Postal credit card application form, this credit card is used to bind the ETC card. After obtaining the credit card, swipe it twice and bring the POS slip to the designated postal outlet to receive and install the ETC on-board device for free, with no charges during the process; Must be between 18 and 60 years old; Own a vehicle under personal name. Below are precautions for installing ETC: Do not block the view, it's best to install it behind the rearview mirror: Many car models have a large inclination angle of the windshield, resulting in a smaller driver's field of vision. If ETC installation does not consider this, it will increase the driver's blind spots. Install it on the right side behind the rearview mirror 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 can be easily blocked. Once installed, do not remove it casually: The button in the middle of the adhesive is an anti-removal guide rod, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal guide rod in. If it is removed casually, the anti-removal guide rod will pop out and trigger the switch, locking the electronic tag and rendering it unusable, requiring a visit to the 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 area is 8 meters. To prevent the ETC device failure of the vehicle in front, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front; The ETC lane recognition speed is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, leading to charging failure; When using a debit card to bind ETC, insufficient balance will also cause charging failure.
The ETC on highways is the Electronic Toll Collection system. With a small box installed in your car, toll fees are automatically deducted when passing through toll stations without needing to stop, saving a lot of time and effort. As a long-distance driver, I deeply appreciate its benefits: manual toll payment used to be a hassle, with queues during peak hours causing delays of up to half an hour. Since using ETC, I zip through toll stations in seconds, saving time and reducing driving fatigue. For example, on my trips from Beijing to Shanghai, passing through seven or eight toll stations, using ETC saves me over half an hour. Additionally, many routes offer discounts, with 5% off being common, and frequent travelers can save thousands over time. Installation is simple—just visit a bank or mobile service point for a free device that sticks to your windshield. It’s also reliable over long-term use, with rare errors; occasional signal issues can be resolved by rescanning. I highly recommend all frequent highway users install one—efficiency soars, and life gets easier.
I've been in automotive electronics repair for many years. ETC stands for Electronic Toll Collection, with its core being the OBU (On-Board Unit) vehicle equipment and RSU (Roadside Unit) infrastructure, operating via microwave or RFID technology. Simply put, when vehicles approach toll stations at 20 km/h, the OBU sends signals to the RSU. After data matching, the toll is automatically deducted from the card in less than a second with virtually no delay. The device consists of a card and sensing module installed inside the windshield - not complex but highly precise, minimizing human error in toll collection. Security is reliable too, with encrypted data preventing fraud. From my repair experience, most failures stem from signal interference or battery depletion, often fixed by just replacing the battery. Key advantages include improved traffic efficiency (doubling toll station capacity), reduced congestion and fewer accidents. I recommend drivers regularly inspect their devices to prevent aging issues. Overall, it's a mature, reliable and practical technology.
