Can ETC be installed at the black dot position?

ETC can be installed at the black dot position, as long as it does not obstruct the driver's view and can detect the toll station's sensing equipment. However, there are also drawbacks to installing it at the black dot area of the windshield—the solar charging capability of the ETC device may weaken, potentially leading to power depletion over time. The working principle of ETC involves dedicated short-range communication between the vehicle-mounted ETC electronic tag and the ETC microwave antenna at the toll station lane. This utilizes computer networking technology to process backend settlements with banks, enabling vehicles to pass through highway or bridge toll stations without stopping to pay fees.
