Can ETC be used if covered by black film?
2 Answers
ETC cannot be installed in black areas. If the ETC is installed in a black area, it will affect the solar charging of the ETC. The ETC electronic tag consumes power, but it usually does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Relevant information about ETC is as follows: 1. Introduction: ETC is an electronic toll collection system for highways or bridges that enables automatic toll collection without stopping. 2. Working Principle: The working principle of ETC involves dedicated short-range communication between the vehicle-mounted ETC electronic tag and the ETC microwave antenna installed in the toll station lane. It uses computer networking technology to process background settlements with banks, allowing vehicles to pass through highway or bridge toll stations without stopping to pay tolls.
As a car enthusiast who loves to modify my ride, I ran into an issue after applying a sleek black window film to my new car—it completely blocked the ETC signal, causing endless delays at highway toll booths. After consulting my mechanic buddy, he explained that the film contained a metallic coating, acting like a tiny Faraday cage that cut off the ETC's radio signals. His solution? Relocate the ETC to an untreated spot on the windshield, which instantly fixed the problem. This taught me a valuable lesson: never sacrifice safety features for aesthetics. Ignoring this could not only disrupt your trip but also lead to extra manual fees if you're stuck holding up traffic. Always test your ETC functionality before hitting the road—don't wait for a crisis to expose the flaw.
