first, ways to avoid the credit card being controlled by the wind: 1. Try to swipe your card in a large supermarket to convince the bank that you are using your credit card normally, not for other purposes. 2. Pay attention to the credit card limit. Repeated credit card swiping is a way to raise the credit card limit. Banks also like such users, but don't blow up the credit card limit every month, which will make banks suspicious. I believe most credit card holders will not do this every month. It is better to control the monthly quota at around 7% as far as possible. Therefore, paying attention to the credit card quota can also avoid the credit card being controlled by the wind. 3. Frequently swipe your card and swipe it all at once or fix it to overdraw your credit card during this time, which will easily make the bank mistakenly think that you are taking credit card funds. This behavior has seriously damaged the interests of the bank, and the bank has cracked down on this aspect. Once it is discovered, it will reduce the quota and freeze the credit card. Second, the solution to the credit card being controlled by the wind: the solution is simple: after receiving the short message from the bank, don't ignore it, ask the reason clearly, and if it is improperly used at ordinary times, solve it in time; If it is due to illegal attacks, system problems and other reasons, please contact the bank in time, verify your identity, and change your password to unlock it.

Extended information: Many industry experts said in interviews that credit card risk control is not only the responsibility and obligation of banks, but also requires cardholders to attach great importance to it. Meng Liwei, a credit card analyst at Yinlv. com, told the Beijing Times reporter that many cardholders lack sufficient understanding of the importance of credit card information, and many cases of credit card theft are caused by cardholders' poor awareness of security.
