Credit card risk control refers to the process of identifying and preventing credit card risks by using various means, methods and technologies. In short, it is a series of risk control measures taken by banks, financial institutions and businesses when issuing or using credit cards. In this process, risk control personnel will identify possible credit card use risks through data analysis, customer credit evaluation and risk strategy formulation, thus ensuring the safety of banks and customers' funds.

With the wide application of credit cards in our daily life, the risks of credit cards are also increasing. Without strict risk control measures, it will lead to customer information leakage, theft and fraud, which will not only bring losses to customers, but also seriously affect the reputation and economic interests of financial institutions. Therefore, establishing a perfect credit card risk control system is an important work that banks, financial institutions and businesses should pay attention to and invest in.

At present, the technical means used in credit card risk control mainly include data mining, risk assessment, identity verification and transaction monitoring. In the process of risk control, using big data technology, banks can conduct risk assessment and credit investigation based on customer transaction records, credit rating history, consumption patterns and other information, and can also analyze and quantitatively predict the data through risk model technology to identify risks more effectively and take prevention and control measures to minimize credit card risks.
