What is the function of ETC?

[VanHarrison]

ETC function: 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. By utilizing computer networking technology for backend settlement processing with banks, the system enables vehicles to pass through highway or bridge toll stations without stopping while automatically paying the toll fees. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Promotes low-carbon travel by reducing noise and exhaust emissions since vehicles don't need to stop at toll stations, thereby minimizing pollution; Cost and wear reduction: Saves expenses by decreasing the frequency of vehicle acceleration and braking, which lowers wear and fuel consumption. Users also enjoy a 5% discount on toll fees; Improved efficiency: The theoretical passing efficiency of ETC lanes can be increased by 2-3 times or more, making traditional ETC systems more updated, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

I've been driving for over a decade, and ETC is truly a great thing. Its biggest advantage is allowing you to pass through highway toll stations without stopping to queue for payment - the barrier automatically lifts as you drive through while deducting the fee, which is extremely convenient. In the past, using manual lanes during peak traffic could mean waiting half an hour, but now it takes just seconds. Additionally, it helps you save money with a 5% discount on toll fees - the more you drive, the more you save. Recently I've noticed some big city parking lots have started using ETC too, with automatic barrier lifting on entry and fee deduction on exit - no more scrambling for change or scanning QR codes. Just remember not to casually remove the device - I did it once myself and reactivation was a nightmare, almost preventing me from entering the highway.

Using ETC is mainly for convenience. When I'm in a hurry to get to work in the morning and take the highway, seeing long queues at the manual toll lanes, I just drive through the ETC lane with a 'beep' and pass directly—it feels great. It not only saves time, but the onboard OBU device communicates with the toll station via microwave, completing the verification and deduction automatically. Nowadays, even car washes accept ETC—last time I used my CCB ETC card to pay for a car wash and got a discount. The only thing to watch out for is ensuring sufficient balance if you link a debit card—I once got restricted because there wasn't enough money in my account. Now, the government is heavily promoting ETC, with many toll stations leaving only one manual lane. Those who haven't installed it really should get one.

The greatest value of ETC is evident during long-distance trips. Last year, I drove to Tibet and passed through over twenty toll stations. If I had to stop at each one to take a ticket and pay, it would have taken me at least two extra hours. ETC relies on onboard devices and gantry systems for automatic identification and fee deduction, allowing seamless travel without slowing down. Nowadays, gas stations and charging piles are also integrating with the ETC system—I recently refueled at a Sinopec station in the city and paid directly via ETC scan. I recommend applying through a bank, as it’s far more convenient than WeChat, and repayment details are easily accessible via mobile banking. Just remember to clean the device from dust in summer—last time, mine was partially blocked and almost failed to scan.

When I first bought a car, I thought ETC was optional, but after using it, I realized how convenient it is. Automatic toll deduction relieves the pressure of carrying cash, and the long-term 5% discount adds up over time. More importantly, it avoids the embarrassment of being honked at by cars behind—those few seconds of waiting for change at manual lanes always invite impatience. Nowadays, ETC devices are solar-powered and don’t require wiring; the one on my car has been working perfectly for three years. On weekends when I take my kids to the mall, the ETC lanes in underground parking are much smoother than other lanes. Just be extra careful when replacing the windshield—my friend forgot to reinstall the ETC after a replacement and got stuck at the toll gate.

ETC acts like a seamless payment assistant for cars. Utilizing microwave communication to automatically identify vehicles, it reduces the traditional 30-second manual toll collection to under 3 seconds. As someone who frequently drives on interprovincial highways, I've noticed that ETC discounts are becoming even more substantial—last time, the Zhejiang section offered a 12% discount. Beyond the convenience of toll passage, what's even more remarkable is its ability to record trip data. I can check my entire year's travel records on the WeChat ETC mini-program. Once, when filing for company travel reimbursement, exporting the ETC bill directly saved me a lot of hassle compared to manual invoices. However, be cautious not to let it get tied to credit card overdue payments—a friend ended up with a credit report mark due to ETC arrears, affecting their car loan eligibility.
