The CVV (Card Verification Value) or CVC (Card Verification Code) is a three- or four-digit number that is traditionally found on the back of credit or debit cards. The code provide a security measure for transactions where the card is not physically present, such as online purchases.
To provide an additional layer of security, the BBVA debit card uses a dynamic CVV. This is not printed on the card, but changes with each transaction to increase protection against misuse.
