Why does China Merchants Bank Card have seven digits on the back like a credit card?
Hello, CVV2 is a verification code. It is a bank card used for indirect credit card consumption occasions, such as online payment and transaction. Generally refers to the last three digits of the seven digits in the signature column on the back of your credit card. For example: 1234

567, just enter 567. The verification code will change every time you change your credit 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 by the customer's own card.

If it is a savings card, you don't need to enter CVV code at present.
