How to test if ETC is working?

Methods to test if ETC is working: First, remove the card and insert the chip-side of the card into the electronic tag. When you hear a "beep" sound and the electronic tag screen displays "Debit Card" or "Balance," it means the system is functioning normally. If the ETC card is inserted into the electronic tag but the screen shows messages like "Electronic Tag Invalid" or "No Card Inserted," it indicates an issue with the electronic tag, and you need to visit an ETC service center to reactivate and reinstall it. ETC (Electronic Toll Collection) is a system that allows for non-stop toll payments. ETC lanes are dedicated to vehicles equipped with ETC onboard units, using electronic payment methods without manual toll booths. The ETC system works through microwave-based short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations. This data is then processed via computer network technology for backend settlement with banks, enabling vehicles to pass through toll stations without stopping to pay bridge or road fees.
As a daily highway driver, the most direct way to test if your ETC works is to drive through a toll station. Slow down to under 20 km/h before entering the ETC lane and keep an eye on the device atop the toll booth. If you hear a beep and the barrier lifts, it means it's working. Also, try removing and reinserting the ETC card a few times to see if the green light flashes—a click sound after insertion means it's reading properly. Don’t peel off the OBU device on your windshield unnecessarily; weak adhesive can weaken the signal. Before hitting the highway, check your card balance—unpaid fees will keep the barrier down. Last time, I got stuck behind and honked at.
You can quickly test your ETC at home by yourself. First, turn on your phone's Bluetooth. Many banking apps have an ETC detection feature. Park your car in an open area with the engine off, press the button on the side of the device to activate it, and use the banking app to scan and identify the device. If it prompts a successful connection and displays the card number, it means the OBU host is functioning properly. Then, insert the card into the device. After hearing a beep, check the indicator light—a steady green light indicates it's working fine. If your windshield film is too thick, it may affect the signal, so it's best to roll down the window during the test.
Here's my simple three-step method to check the ETC: First, see if the green light on the device is blinking. Second, listen for the prompt sound when inserting the card. Third, check the balance on the mobile app. Pay attention to the device when starting the car in the morning - it normally flashes the green light a few times for self-check. Try using the ETC to pay at a supermarket parking lot; if it recognizes it, then it's working properly. Remember not to apply metal film on the windshield - last time, the film I applied caused signal interruption, and the toll gate wouldn't lift, delaying me for half an hour.
