What does the ETC electronic tag mean?
1 Answers
ETC electronic tag refers to the OBU device, which is installed on the vehicle's windshield and communicates with the microwave antenna in the ETC lane at toll stations via dedicated short-range communication. It uses computer networking technology to perform background settlement processing with banks, thereby enabling vehicles to pass through highway or bridge toll stations without stopping while paying the fees. The ETC installation process is as follows: Upon receiving the device, first check whether the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU; the red light will briefly turn on, and the OLED screen will display "Tag Invalid" and "Please Insert Card," indicating the device is functioning normally. Clean the front windshield to ensure the glass surface is smooth, clean, and dry. Then peel off the adhesive backing film of the OBU and attach it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device.
