after the cardholder uses the credit card limit, the bank charges a certain interest, which is the overdraft interest.

There are two kinds of overdraft interest:

First, overdraft consumption interest:

The interest rate is .5% per day, but credit card overdraft consumption generally has an interest-free period of 25 to 56 days, so as long as the cardholder repays in full on time, he can enjoy this benefit; When the payment is not made in full, the bank will calculate the interest from the day you spend it until you pay off the current bill.

Second, overdraft interest:

The interest rate of this interest is .5% per day, but it has no interest-free period, and the cardholder needs to repay the cash withdrawal amount and interest on time.
