What is the normal working display of ETC?
3 Answers
When the electronic tag screen displays "Debit Card" or "Amount", it indicates that the ETC is in normal working condition. Below is relevant information about ETC: 1. Introduction to ETC: The Chinese translation is Electronic Toll Collection, which is an automatic toll collection system for highways or bridges. It utilizes dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at toll stations, along with computer networking technology for backend settlement processing with banks. 2. Current Development Status of ETC: ETC is an electronic automatic toll collection system being actively developed and promoted internationally for roads, bridges, and tunnels. This technology has a relatively long development history abroad, and electronic toll collection systems in many countries and regions such as the United States and Europe have been partially networked and gradually formed scale benefits.
I have an ETC installed in my car, and usually its small green light blinks intermittently, just like a breathing light. When passing through a toll station, the changes are more noticeable. Dozens of meters away from the sensing area, the green light suddenly starts blinking faster, followed by a beep, and the screen displays the deducted amount or shows 'transaction successful.' At this moment, the barrier lifts promptly. If the device screen also constantly displays the balance or the last few digits of the card number, it indicates that the card reading is functioning normally. The only thing to watch out for is if the green light turns red or doesn't light up at all—this usually means the device is either out of battery or has poor contact. Just glance at the indicator light's status before driving, and generally, there's nothing to worry about.
Last time when I installed the ETC for my new car, I specifically asked the staff. During normal operation, the device should have a green indicator light, some stay continuously lit while others blink intermittently. When passing through the toll station, there will be more noticeable responses: first a beep sound as a prompt, followed by the screen displaying the specific deduction amount. Some devices may also pop up a transaction success notification. It's also normal if it displays the balance or bank name. I've tried it several times myself, as long as the green light is on, passing through the gantry is always very smooth. Remember that the device requires solar charging, so if parked in an underground garage for a long time, pay attention to the battery level. If the display dims, it needs to be moved into sunlight.
