3-digit Credit Card Security Code

What is the Security Code?
Card security code (CSC) alternatively known as Card Verification Code (CVV2), Card Validation Code (CVC2) or Card Identification Number (CID) is usually a three (3) or four (4) digit number, which is an important new Internet security feature that now appears on the back of Visa, MasterCard, and Diners Club cards, usually in the signature field. American Express cards use a 4 digit CSC on the front of the card.
The CSC provides a cryptographic check and helps validate that the customer placing the online order actually is in possession of the credit card and that the credit/debit card account is legitimate.

Do I have to enter this Security Code?
YES, you must enter the code. Visa, MasterCard, Diners Club and American Express now require online stores to obtain the card security code for all cards that have a code printed on them. Orders cannot be processed without a valid CSC.
