Legal analysis: If the amount of credit card bad debt is not large, the bank will generally not sue because the cost of prosecution is relatively high. The bank will at most blacklist the user. If the amount of bad debt is large, the bank will sue the user. When it is determined that the overdraft credit card is malicious and there is credit card fraud, the user may be required to bear corresponding criminal liability.

Generally speaking, credit card debt is not a civil dispute. Therefore, in order to avoid escalation of the situation, it is best for users to settle the credit card debt as soon as possible.

Legal basis: Article 196 of the Criminal Law of the People's Republic of China and the People's Republic of China. Whoever commits credit card fraud in any of the following circumstances and the amount is relatively large shall be sentenced to fixed-term imprisonment of not more than five years or Criminal detention and a fine of not less than 20,000 yuan but not more than 200,000 yuan; if the amount is huge or there are other serious circumstances, the person shall be sentenced to fixed-term imprisonment of not less than five years but not more than 10 years and shall also be fined not less than 50,000 yuan but not more than 500,000 yuan; if the amount is particularly huge Or if there are other particularly serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than ten 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 counterfeit credit card, or Using a credit card fraudulently obtained with false identification;

(2) Using an expired credit card;

(3) Pretending to use another person’s credit card;

(4) Malicious overdraft.

The term "malicious overdraft" as mentioned in the preceding paragraph refers to the cardholder's behavior of overdrafting beyond the prescribed limit or within the prescribed period for the purpose of illegal possession and failing to return the card after being called upon by the card-issuing bank.

Whoever steals a credit card and uses it shall be convicted and punished in accordance with the provisions of Article 264 of this Law.
