The credit card security code is a crucial three-digit number in the signature column on the back of the credit card. It plays an identification role in online payment and telephone payment. Please keep it carefully and never disclose it to others. In daily consumption, whether eating out or shopping, you should avoid letting others brush the cards on your behalf and ensure that the cards are always in sight to prevent the magnetic stripe information from being stolen.

In order to enhance the security of online payment, banks will send SMS verification codes. However, please note that any telephone request for verification code or security code is likely to be fraud. It is necessary to be vigilant when dealing with such situations.

In order to further prevent the credit card from being stolen, it is suggested to upgrade to a chip card, such as the all-currency international chip card of Bank of China, which adopts advanced encryption technology and has higher security and reliability. At the same time, choose password and signature verification when shopping to ensure that the card does not leave the line of sight every time, carefully check the information on the purchase order to confirm that the amount is correct and the card belongs to me.

generally speaking, protecting the security code of credit card, taking appropriate anti-fraud measures and choosing a safe payment method are the key steps to ensure the security of credit card. Please be sure to form a good habit of using the card.
