1, try to swipe your card in a large supermarket.

The purpose of swiping a card in a large supermarket is 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 swiping is a way to increase the credit card limit. Banks also like such users, but don't brush the credit card limit every month, which will make banks suspicious. I believe that most credit card holders don't do this every month. It is better to control the monthly quota at around 70% as far as possible. Therefore, paying attention to the credit card limit can also avoid the credit card being controlled by the wind.

3. swipe your card frequently.

If you swipe your card at one time or overdraw your credit card during this time, it is easy for the bank to mistakenly think that you are taking credit card funds. This behavior has seriously damaged the interests of banks, which have dealt a great blow to this aspect. Once found, it will lower the limit and freeze the credit card.

Second, the solution of credit card being controlled by wind:

The solution is simple: after receiving the short message from the bank, don't ignore it, ask the reason clearly, and solve it in time if it is not used properly; If it is because of illegal attacks, system problems, etc. , you can cooperate with the bank in time to verify your identity and change your password.

Extended data:

Many industry experts said in an interview that credit card risk control is not only the responsibility and obligation of banks, but also the great concern of cardholders.

Meng Liwei, a credit card analyst in Yinlv.com, told the Beijing Times that many cardholders lack sufficient understanding of the importance of credit card information, and many cases of credit card theft are caused by poor security awareness of cardholders.

In order to improve the safety awareness of cardholders, it is necessary for banks to inform cardholders what kind of card use behavior is likely to lead to the theft of credit cards, and regularly remind cardholders to prevent credit cards from being stolen.

Meng Liwei suggested that cardholders should do the following four things to protect their cards:

First, do a good job in keeping personal identity information and credit card information confidential, and don't easily disclose credit card number, expiration date, verification code and other information to others;

Second, credit card withdrawal and other businesses should be handled through formal channels of banks;

Third, don't open all kinds of fast payments at will, open transaction reminders, and keep abreast of credit card transactions;

Fourth, don't click on unknown links or WiFi links from unknown sources at will to prevent Trojan virus in computers, mobile phones and other devices from causing credit card theft.
