second, how to spend the credit card overpayment. Since there is a handling fee for withdrawing the credit card overpayment, can I spend it directly by swiping the card? The answer is yes, and when there is an overpayment in your credit card, you will be given priority to deduct the overpayment by swiping the card, and the next bill will be generated only after the overpayment is deducted. It is not recommended to deposit too much money into the credit card, so you don't enjoy interest, and you need to pay a handling fee to withdraw cash. Although the overpayments of Bank of China, ICBC, China Construction Bank, Bank of Communications, Minsheng, Huaxia and Shanghai Pudong Development Bank are withdrawn by the Bank, there is no handling fee. However, in order to maximize your interests, it is suggested that you directly bind your credit card to the relevant debit card and implement automatic deduction and repayment.
