Although there is no time limit for credit card swiping of China Merchants Bank, try not to swipe your card too late. After 22 o'clock in the evening, except for 24-hour convenience stores, bars, entertainment centers, snack bars and other places, it is best for other merchants not to use credit cards after 10 at night. Because the normal business hours of most businesses are between 8: 30 a.m. and 10: 00 p.m., if it is not the abnormal consumption during these periods, banks will easily suspect that users are cashing out, and the cashing operation is illegal, which will easily lead to an increase in account risk, which will be controlled by banks, and the credit limit may be reduced or even frozen.
In addition, whenever you swipe your card, be sure not to skip the code. For example, when you swipe your card in a fruit shop, you show the bill in a jewelry store. Also, pay attention to the large amount of credit card. This situation is easily suspected by banks.
