1, the interest and late payment fee for credit card arrears are determined according to the specific situation and the contract. If you don't pay back for a long time or only pay the minimum amount, you will often have high interest and late fees, which will lead to the continuous increase of the amount owed. In the above-mentioned cases, from the amount owed to more than 40,000 now, there are cases where the repayment has not been made for a long time or only the minimum repayment amount has been paid, so the total amount owed continues to accumulate, resulting in high interest and late payment fees. So it's normal for credit cards to owe more than 40 thousand now.

2. Credit card is a payment tool issued by banks or other financial institutions, which allows cardholders to use credit lines to spend in specific merchants and places.
