If you are detained or imprisoned for a crime and your credit card cannot be repaid, you can entrust others to handle it on your behalf. Because the debtor is suspected of committing a crime, his personal freedom is restricted and he cannot be exempted from the responsibility of the credit card. Banks have the right to sue. It is suggested that the parties actively communicate with the bank or contact their family and friends to handle it on their behalf, otherwise it may constitute credit card fraud. According to the first paragraph of Article 196 of the Criminal Law: "In any of the following circumstances, if the amount of credit card fraud is relatively large, it 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 shall be imposed; 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. The second paragraph stipulates: "The malicious overdraft mentioned in the preceding paragraph refers to the behavior of the cardholder who 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.
