Major banks have been acting frequently, and many cardholders' credit cards have been controlled by the wind. They have either been reduced or blocked, mainly because of the wrong way of using the cards. Then, how to swipe a credit card will not be controlled by the wind? Here are a few tricks to teach you. 1. Card swiping during normal business hours Except for convenience stores, hotels, entertainment centers, etc., the normal business hours of most merchants are from 8: am to 1: pm. If you often swipe your card in the middle of the night, and all the merchants who are closed during normal hours, it is easy for banks to detect that you are using your card illegally, especially if the amount of card swiping is large and the frequency is frequent, the more likely it is to be controlled by the wind.

2. Diversified consumption is very important. If you spend money in the same merchant for a long time, or often in the same POS machine, the bill list is too single, and the bank will also think that it is suspected of unsafe card use and risk control. Therefore, the correct swipe posture should be spent by different types of merchants, preferably covering areas such as food, clothing, housing and transportation, and the amount of spending should match the types of merchants, such as swiping dozens of cards at breakfast shops and tens to hundreds of cards at restaurants.

3. Participate in more banking activities. Many banks cooperate with many merchants in some preferential activities, such as the fifth day of the most popular signboard activity of Bank of Communications, Guangfa Sharing Day, etc. Cardholders can make profits by swiping their cards at these merchants and accumulate points themselves, which can be described as a win-win situation.

4. The consumption methods should be diversified. In addition to offline credit card swiping, online consumption should be combined. In addition, credit card swiping should not only use POS machines. For example, there are many merchants who can collect money by QR code and support Alipay and WeChat scan code payment. By the way, it is best to choose a cleaning machine for brushing POS machines. The rate of this kind of machines is .6%. Most of them are second cleaning machines below this standard, which are easy to skip codes and have no points, and are also easily subject to bank risk control.
