What is CVV2

CVV2 stands for Card Verification Value 2, and it is a three or four-digit security code that is typically printed on the back of a credit or debit card. It is used as an added security measure to help prevent fraudulent transactions when the card is not physically present during a purchase. The CVV2 code is different from the card's magnetic stripe data and the embossed card number, making it more difficult for thieves to use stolen card information for online or telephone purchases. When making a purchase, the merchant may ask for the CVV2 code to verify that the person using the card has it in their possession. It is important to keep the CVV2 code confidential and not share it with anyone to protect against unauthorized use of the card.
