It is not uncommon for credit card information to be leaked nowadays. The reason for this is generally because many people do not know how to protect their credit card personal information. In order to protect their credit card security, the editor below will introduce it to you. Let’s take a look at how to protect personal credit card information.

How to protect the security of credit card personal information

When an ordinary cardholder reaches the credit card limit assessment standard, the bank will notify the customer via text message and let them choose whether to increase the limit. Even if it is a temporary limit adjustment, the cardholder still needs to call the credit card center to adjust it himself.

In addition, when paying online with a credit card, the cardholder generally only needs to provide card number, validity period, security code, password and other information. Some do not even require a password, so the above information must be kept strictly confidential. Be vigilant about requesting the above information in any of the above forms, because once it is leaked, with the development of various bank credit card centers, more and more promotional information will not be delivered to cardholders through outbound phone calls. More The information may come from SMS, email, app or WeChat client; secondly, the staff of the real credit card customer service center will not actively ask the cardholder to provide the card number, validity period and cvv2 information, especially in the case of non-online payment. The chances of being asked for cvv2 are very slim. What should I do if I do get a call from my bank’s customer service asking for similar information? The best way is to find an excuse to hang up on the customer service phone number, and then call the credit card center customer service number to inquire.
