The back of a credit card is located in the signature area on the back of the credit card. The back of the card includes the last four digits of the card number and CVV2. For example, the number on the back of the card is 6532757, so 6532 is the last four digits of the card and 757 is the CVV2 of the card. CVV2 can be used for convenient transactions. Users only need to provide information such as card number, expiration date, CVV2, verification code, etc., and can complete payment without a credit card password.

Of course, this convenient payment method also has certain security risks. Users are advised not to keep their credit cards and not to disclose these private information.

what does the logo on the back of the card mean?

The logo on the back of the card is usually composed of seven digits, the first four digits are the last four digits of the user's card account number, and the last three digits are the security code of the card. The security code is very important. Users should be careful not to disclose the security code of the card when swiping the card. For credit cards, if users change their credit cards, even if the first four digits are the same, the security codes of the last three digits will change.
