Does the ETC card have a front and back side?
1 Answers
ETC cards have two sides, with the side containing the chip being the front. The front side should face the car window and be inserted into the card slot of the OBU device. Where can ETC be installed: For small vehicles such as cars and minivans, the OBU device is installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part. ETC installation position requirements: The height should be no less than 1.2 meters and no higher than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane). The ETC installation process is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly turn on. The OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning normally. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick it to the installation position. Press firmly with your hand for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the front windshield, ensuring the chip is inserted into the OBU device.
