ICBC credit card does not have a time-limited service. If the payment is not received after the repayment date, it is overdue, and will be included in the credit report, and interest, penalties, and late payment fees will be charged.
Except for repayment from the Bank, other repayment methods may have a delay of more than two days. To be on the safe side, when repaying through other methods, you should pay at least two days in advance.
