The ways of overdraft are: offline credit card, online shopping, cash withdrawal, etc.
If it is only a credit card overdraft, as long as it can be repaid in full and on time, it can be interest-free. If the overdraft is withdrawn, it is necessary to repay the principal and interest on time and pay the withdrawal fee.
After the credit card is overdrawn, you must repay it on time. If you are worried, you can choose to pay the most or apply for installment repayment. Never overdue.
