How to check if ETC is working properly?

[SanCameron]

ETC status can be checked through the following methods: 1. Remove the card and insert the chip side into the electronic tag. When you hear a "beep" sound and the electronic tag screen displays "Debit Card" or "Balance", it means you can normally pass through the ETC lane. 2. If the ETC card insertion shows messages like "Electronic Tag Invalid" or "No Card Inserted" on the electronic tag, it indicates an abnormality with the electronic tag. You need to visit an ETC service outlet for reactivation and reinstallation. 3. Additional information: ETC works through 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. It uses computer networking technology for background settlement processing with banks, allowing vehicles to pay highway or bridge tolls without stopping at toll stations.
