What should I do if I forget my credit card dvc code?
CVV2 is a three-digit number printed at the end of the signature column on the back of the card, and the CVV2 code is generally checked during off-site transaction/manual transaction (the card cannot be swiped). If CMB credit card is used, the verification code can only be viewed through your own card. Forgetting can only be a damaged card, or you try to apply for a new card.
