CVV2 code is a kind of verification code, also known as security code, which is used for checking when credit cards are swiped indirectly (such as online payment). Generally, it is the last three digits of the seven-digit signature column on the back of your bank card. For example: 1234 567, just enter 567.

The verification code will change every time you change your bank card. If it is blurred, you can cover it here with white paper and draw it repeatedly to show these three numbers.

If the input error is locked for many times, it will be recovered the next day. This verification code can only be viewed through your own card.
