What is a CVV?
The Card Verification Value (CVV) is a three- or four-digit number printed on credit and debit cards. It serves as an additional layer of security during online transactions.
Why is CVV Length Important?
The length of the CVV is important because it helps prevent unauthorized use of your card. A longer CVV is more secure and harder to replicate.
