Will V-KOOL VK70 affect the use of ETC?
3 Answers
V-KOOL VK70 will not affect the use of ETC, as the film material is still plastic and will not interfere with wireless signals. 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 "Label Invalid, Please Insert Card," indicating the device is functioning properly. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick it to the installation position. Press firmly 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, ensuring the chip is inserted into the OBU device. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Promotes low-carbon travel, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption. Users also enjoy a 5% discount on toll fees; Improved efficiency: ETC lanes can theoretically increase vehicle throughput by 2-3 times, making traditional ETC faster, more efficient, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
Having been active in car enthusiast circles for over a decade, I've frequently encountered issues with car window tinting affecting ETC functionality. While the thermal insulation performance of V-KOOL VK70 film is indeed outstanding, it belongs to the metal-based material category. Since ETC systems rely on 5.8GHz radio wave communication, the metallic coating may absorb or reflect signals, causing ETC devices to malfunction at toll stations. I recommend informing technicians in advance to reserve a clear window for ETC installation when applying the film, or considering switching to non-metallic ceramic films like the V-KOOL V70 series. In practice, don't rush to apply full-coverage tint—conduct small-scale signal strength tests first. If problems occur after installation, promptly visit professional shops for cutting and repair to avoid ETC failures causing toll delays during highway travel. After all, driving convenience is paramount, and small preventive measures can save significant trouble.
I've been driving to and from work for over a decade. Last year, I installed V-KOOL VK70 window film, but then my ETC kept failing to read at toll stations with extremely weak signals. At first, I thought the device was broken, but ETC customer service confirmed it was working fine. Eventually, I discovered the metal layer in the film was causing interference. The solution was simple: either have the installer cut a small hole in the film at the ETC position on the windshield, or relocate the ETC device to an untreated area. This taught me that while premium films are great, they need to be compatible with other accessories – it's wise to consult the installer and test the signal beforehand. Fixing such issues promptly in daily life saves time. While there's no major safety concern, it's important not to overlook these small details.
