Card security code

A card security code (CSC; also known by several other names) is a series of numbers in addition to the bank card number which is embossed or printed on the card. The CSC is used as a security feature for card not present transactions, where a personal identification number (PIN) cannot be manually entered by the cardholder (as they would during point-of-sale or card present transactions). It was instituted to reduce the incidence of credit card fraud. Contactless card and chip cards may electronically generate their own code, such as iCVV or a dynamic CVV.
