The security code is a new security feature for credit cards. All newly
issued credit cards feature an additional three-digit number that appears
after the card number on the back of the card. These numbers appear on
the credit card and are stored in the credit card company's database. This
security code can be used to verify that the customer is the true
cardholder.
