Overpayment:
When the repayment amount of the credit card is greater than the amount owed, the extra branch will be displayed as a negative number, which is the so-called overpayment.
1. Overpayment is accumulated on the credit line, which will be given priority in the next consumption;
2. When the overpayment is withdrawn, you may need to pay the formalities fee (different banks charge different fees); If China Merchants Credit Card overpays for cash withdrawal, it needs to pay the formalities fee, generally 1%/ transaction, with the minimum 1 yuan/transaction, and some banks do not need the handling fee.
