Legal analysis: overdue repayment not only includes the minimum unpaid part of 5% overdue fine, but also the full penalty interest on the bill (the daily interest rate is 0.5 ‰, the interest will be paid on the day of consumption, and the interest will be recovered on a monthly basis until the principal and interest are paid off), and it will also produce bad credit records in the Credit Information Center of the People's Bank of China, which will seriously affect the application for credit cards and bank loans within five years.

Legal basis: Article 196 of the Criminal Law commits credit card fraud under any of the following circumstances. If the amount is relatively large, it shall be sentenced to fixed-term imprisonment of not more than five years or criminal detention, and shall also be fined not less than 20,000 yuan but not more than 200,000 yuan; If the amount is huge or there are other serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than five years but not more than ten years, and shall also be fined not less than 50,000 yuan but not more than 500,000 yuan; If the amount is especially huge or there are other particularly serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than 10 years or life imprisonment, and shall also be fined not less than 50,000 yuan but not more than 500,000 yuan, or his property shall be confiscated: (1) using a forged credit card or using a credit card fraudulently obtained with false identification; (2) Using an invalid credit card; (3) Fraudulent use of another person's credit card; (4) malicious overdraft. Malicious overdraft refers to the behavior that the cardholder overdraws beyond the prescribed limit or time limit for the purpose of illegal possession, and refuses to return it after being urged by the issuing bank.
