Legal analysis: credit card fraud over 5000 yuan can be filed. According to the laws of our country, the amount of fraud is divided into large amounts, and the amount is huge. In the crime of credit card fraud, the amount of more than 5000 yuan is relatively large, and the public security organ should file a case for investigation.

Legal basis: Provisions of the Ministry of Public Security of the Supreme People's Procuratorate on the standards for filing criminal cases under the jurisdiction of public security organs (II).

[Crime of Credit Card Fraud (Article 196 of the Criminal Law)] Anyone who commits credit card fraud and is suspected of any of the following circumstances shall file a case for prosecution:

(1) Using forged credit cards, or using forged identity documents to defraud credit cards, or using invalid credit cards, or fraudulently using other people's credit cards to engage in fraudulent activities, with an amount of more than 5,000 yuan;

(2) Malicious overdraft, the amount of which is more than 1 10,000 yuan.

The term "malicious overdraft" as mentioned in this article refers to the behavior that the cardholder overdraws beyond the prescribed limit or time limit for the purpose of illegal possession, and has not returned it for more than three months after being repeatedly urged by the issuing bank.

Malicious overdraft, the amount of which is more than 1 10,000 yuan but less than110,000 yuan, has been fully repaid before the public security organ files a case. If the circumstances are obviously minor, criminal responsibility may not be investigated according to law.
