There is no handling fee for credit card transfer and repayment, and the credit card limit is returned in real time, and the cash advance limit needs to be returned after it arrives (it takes 2 days for credit card payment to arrive).
The inter-bank repayment of our credit card depends on the clearing system adopted by the transfer bank, and it usually takes a certain time to arrive at the account (it is recommended to transfer 2-3 working days in advance).
If the associated card has automatic deduction, the system will automatically deduct it on the deduction day, and the credit card limit will be restored in the early morning of the next day.
