When is the ETC fee deducted after passing the highway?

[EthanFitz]

After passing the highway, the ETC fee is generally deducted within 2 to 30 days. Except for the immediate deduction of ETC stored-value cards, ETC debit cards are usually deducted on a periodic basis. The efficiency of ETC fee deduction may vary in different regions. ETC is an electronic toll collection system that does not require stopping. ETC uses electronic payment methods, and the ETC non-stop toll collection system is an advanced method for road and bridge toll collection. The working principle of ETC is through microwave dedicated short-range communication between the vehicle-mounted electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, using computer networking technology to perform background settlement processing with the bank, thereby achieving the purpose of vehicles passing through road and bridge toll stations without stopping to pay tolls.
