The '''Card Security Code''' ('''CSC'''), also called '''Card Verification Value''' or '''Code''' ('''CVV''' or '''CVC'''), is a security feature for [[credit card]] transactions. Most credit cards have two card security codes. The first, often called CVC1 or CVV1 is encoded in the magnetic stripe of the card and is used for in-person transactions. The second card security code, known as CVV2 or CVC2 is used to secure transactions occuringoccurring over the Internet, by mail, or over the phone. It is a 3 or 4 digit value printed nowhere except on the card, and can theoretically be used to verify that the buyer has the card in their physical possession, giving merchants protection against [[credit card fraud]].

Cardholders do not need to worry about fraud thanks to zero-liability policies from major card issuers.
