How to Tell if ETC is Functioning Normally?

[DeGideon]

Methods to determine if ETC is functioning normally: Insert the ETC bank card with the chip facing forward into the electronic tag. If the ETC device's green light flashes once and the screen displays "Debit Card" or shows the amount, it indicates normal operation. If inserting the ETC card into the electronic tag displays messages like "Electronic Tag Invalid" or "Card Not Inserted," it means the electronic tag is malfunctioning and requires reactivation and reinstallation at a service outlet. ETC (Electronic Toll Collection) is an automatic toll system for highways or bridges. It utilizes dedicated 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, with backend settlement processing conducted through computer networking technology with banks.
