What to do if the ETC adhesive is not strong enough and falls off?

If the ETC falls off, it cannot be used anymore. You need to take the original vehicle, the ETC device, and the bound bank card to the ETC device installation location to reactivate the device. The ETC installation process is as follows: Upon receiving the device, first check whether the ETC card and the 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 "Label Invalid" and "Please Insert Card," indicating that the device is functioning normally. Clean the windshield to ensure the glass surface is smooth, clean, and dry. Then peel off the adhesive backing film on the OBU and attach 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 windshield. The chip should be inserted into the OBU device.
A few days ago, the ETC tag on my car suddenly fell off. At first, I thought it was because the weather was too hot and the glue melted, but upon closer reflection, this kind of issue is actually quite common. It might be that the glass wasn’t completely clean, with oil stains or dust sticking to it. My suggestion is not to rush to reattach it immediately. First, check the glue on the back of the tag—if it still has some stickiness, use a hairdryer on low heat to soften it. Then thoroughly clean the contact area on the windshield with alcohol and wait for it to dry before pressing the tag firmly back in place. If that doesn’t work, consider buying special automotive glass adhesive or ordering ETC-specific double-sided tape online. Remember, a fallen ETC tag not only affects toll booth passage but could also get blown away by the wind, leading to the hassle and cost of reapplying. I usually recommend checking the attachment during annual maintenance to avoid regrets when problems arise.
