Why doesn't ETC automatically deduct fees?

[MacClara]

For post-paid ETC toll stations, fees are not deducted immediately. You need to wait for the highway company to settle accounts with the bank at fixed intervals, which usually takes about 3 days, or up to a week in some cases. Regulations vary by province. More information about ETC is as follows: 1. ETC is an electronic automatic toll collection system for highways, bridges, and tunnels that is being actively developed and promoted internationally. 2. The ETC system uses automatic vehicle identification technology to establish wireless data communication between vehicles and toll stations, enabling automatic vehicle recognition and exchange of relevant toll data. By employing computer networks to process toll data, it achieves a fully automated electronic toll collection system without the need for vehicles to stop or toll booths to be staffed.
