Can ETC be used without sticking it on the windshield?

[DeBrayden]

It is possible to use ETC without sticking it on the windshield, as long as the sensing device at the highway toll station can detect the ETC device. You can install it on the car's dashboard or simply hold it up when passing through the toll station. ETC is an electronic toll collection system for highways or bridges that allows for automatic payment without stopping. The working principle of ETC involves dedicated short-range communication between the onboard ETC electronic tag installed on the vehicle and the ETC microwave antenna on the toll station lane. This utilizes computer networking technology to perform background settlement processing with the bank, enabling vehicles to pay highway or bridge tolls without stopping when passing through the toll station.
