etc can be bound to existing credit cards.

After the user applies for the etc card and OBU equipment, he still needs to bind the etc card with the bank card, and the system will debit the bank card. This bank card can be a debit card or a credit card. If you choose to bind a credit card, it will definitely be too late to apply for a new credit card, so just bind the existing credit card.

After binding a credit card, the repayment time is the credit card repayment date, and the ETC deduction will be recorded together with the daily consumption amount of the credit card.
