How to fill in the last three digits of the signature column on the back of China Merchants Bank Card?
CVV2 is a three-digit number printed at the end of the signature column on the back of the card. Generally, the CVV2 code is checked during off-site transaction/manual transaction (card swiping is not allowed). If you use China Merchants Bank credit card, the verification code can only be viewed through your own card.
