So how do banks generally judge that credit cards have potential risks? A friend who works in a bank told me that banks mainly rely on these two points to judge whether cardholders have potential trading risks. Let's take a look at them together.
First: online transaction monitoring
Generally speaking, China's current credit system is not perfect, and enterprises and individuals will indeed encounter corresponding risks when using this system. Therefore, in order to ensure the safety of funds and the interests of cardholders, banks will control the risks of credit cards.
Banks use online transaction monitoring to identify credit card risks, which generally means that banks use machines to monitor and operate and collect information such as education, age, debt and work of credit card holders.
Look at the cardholder's time, amount, place, transaction times and other specific behaviors, and then use the relevant risk formula to refer to the weight. If the cardholder's weight is abnormal, the credit card will be found by the bank, thus avoiding the situation that the credit card is falsely swiped.
Second: Comparative survey of risk data
As a financial institution, banks have no right to interfere too much with the consumption behavior of merchants and individuals. So in many cases, banks find out which credit card transaction is risky and compare the risk data.
For example, refer to previous credit card risk cases, or see whether the business itself is normal, whether the cardholder's credit card is abnormal, and so on. Through a series of data comparison.
For example, your credit card is often spent in China, and then one day your credit card will be spent in China sooner or later. At noon, a large-scale transaction suddenly appeared abroad, and it was also in the high-risk area of credit card transactions, such as some countries with high card theft in Southeast Asia, and banks basically thought that this credit card was risky.
In this case, the general bank staff will call you to confirm or seal the card for you to reduce the property loss of the card.
If your credit card is risky, it is likely to endanger your property safety. You can cancel your card and replace it with a new one according to the advice of the bank staff. If you think it's too much trouble, you can also modify the consumption password of the credit card, and then limit the consumption quota to protect your property.
It is based on the above two points that banks judge whether cardholders have risky transactions, although we can avoid these situations. It is recommended that friends who want to increase the quota quickly spend as much as possible.
