Why is there no deduction when exiting the highway with ETC?

[OMelanie]

Generally, there are two situations when no deduction information is received: 1. SMS notification service is not activated or the minimum deduction amount is not reached: Currently, most banks charge for SMS notifications. If this service is not activated, you won't receive deduction notifications; 2. Settlement time between the highway company and the bank: For highway tolls, the highway company is responsible for charging. After ETC records the transaction, some banks deduct fees immediately, while others wait for the highway company to submit accounts to the bank at fixed intervals before making deductions. This period is usually about 3 days, or up to a week in some cases, depending on different provincial regulations.
