At present, most credit cards are debit cards, which are paid after consumption and have a certain interest-free period, generally ranging from 20 to 50 days. If you pay back in full within the interest-free period, you don't have to pay interest. After the interest-free period, you have to pay five ten thousandths of the daily interest and a late fee of 10 to 20 yuan.
