CVV2 : Business Definition

For your security, we collect the customer 3 or 4 digit verification number from your bank card to prevent the fraudulent use of your account. The customer verification number is a non-embossed number located on your card that cannot be obtained easily by using an imprint of your card or simply copying down the account number. This verification code is called CID for American Express cards, and CVC2 or CVV2 for Visa, MasterCard and Discover. This verification number helps us to validate that this card is in your possession and that the number is legitimate.
