Credit card overdraft refers to a consumption behavior of withdrawing cash through a credit card, usually called "credit card cash withdrawal" or "credit card cash withdrawal". Cardholders can use their credit cards to withdraw cash at self-service machines or counters provided by banks within the withdrawal limit. However, it should be noted that in credit card advance, the bank will charge certain cash withdrawal fees. Therefore, cardholders need to know the relevant fee information of their credit card overdraft in advance.

Credit card overdraft has certain advantages over other borrowing methods, such as bank loans or consumer credit. Because credit card overdraft does not require collateral or guarantees, the threshold is relatively low, and the overdraft procedure is relatively simple and quick. However, since the interest rate of credit card overdraft is relatively high, generally above 1, it will generate a large interest burden. In addition, if the repayment cannot be made in time, penalty interest and late payment fees will be incurred, which will lead to the overdraft principal and interest rising exponentially, thus forming a debt trap.

In order to avoid credit card overdrafts and high cash withdrawal fees, cardholders need to make detailed repayment plans in advance and repay the outstanding balance before the repayment date. At the same time, cardholders also need to understand the details of handling fees incurred by credit card overdrafts and the settlement calculation method of the balance on the repayment day through official bank channels. Finally, when using credit cards, cardholders need to be cautious in spending and properly handle overdraft issues when necessary to avoid the negative impact of credit card overdrafts.
