If the user fails to pay off the current balance before the final repayment date, he or she will need to pay interest and late fees to the bank.

2. Irrational consumption. Precisely because credit cards are very convenient and fast to use, they don’t look like banknotes that are spent one by one and make you feel distressed. Some irrational consumers tend to consume blindly, spend money like water, and regret it when they finally repay.

Generally, banks will launch a campaign of "swiping the card 6 times within a year to waive the annual fee for the next year". This will encourage users in disguise to swipe the card, otherwise they will be charged the annual fee for the second year, which will increase the number of users. consumption.
