How to install an ETC card?
3 Answers
ETC card installation method: 1. Install the ETC sensor on the black dot area of the car's front windshield inside the vehicle, ensuring it does not obstruct the driving view; 2. ETC sensors have two power supply methods: solar charging and wired charging. Insert the sensor's wire harness plug into the sensor's connection port. For wired charging, connect it to the vehicle's power supply; 3. Apply for an ETC-specific card and insert it into the sensor. ETC is an electronic toll collection system that enables vehicles to pass through toll stations without stopping to pay tolls. It achieves this by using dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, along with computer network technology for backend settlement processing with banks.
When helping my friend install the ETC last time, I followed the instructions carefully and found it quite simple. First, clean the dotted area on the front windshield, peel off the protective film from the double-sided tape on the back of the device, and firmly press it for 30 seconds on the right side of the rearview mirror where it doesn't obstruct the view. Then, turn on the phone's Bluetooth, scan the device's QR code with the bound mini-program to enter the activation page. Note that when inserting the card, the metal side should face the front of the car, and a beep sound indicates successful power-on. Finally, click the activation button in the mini-program and wait for the progress bar to complete. Remember not to rush to remove the card; test it by driving to the ETC lane—if the barrier automatically lifts, it's truly successful. Don't press the button on the back of the device randomly; moving it will require reactivation, which is particularly troublesome.
The key to installing ETC is choosing the right position and activating it successfully on the first try. The front sticker must be placed on the black dotted area, otherwise the solar panel won't charge. For metal film windshields, you need to cut a square hole - my neighbor kept losing signal because they didn't. Wipe the glass three times with alcohol swabs before peeling the adhesive, it cleans much better than wet wipes. Double-check your card balance before insertion, I've seen people waiting for activation with empty cards. During activation, the vehicle must be powered on but not started, keep windows closed to reduce signal interference. Some models require uploading vehicle registration photos, so keep your green book in the glove compartment ready for convenience.
