Line 1:
The '''Card Security Code''' ('''CSC''') a.k.a. '''Card Verification Value''' or '''Code''' ('''CVV''' or '''CVC''') - is a security feature for [[credit card]] transactions on the Internet and 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 some protection against [[credit card fraud]].
Unfortunately, the primary way that criminals get credit card information for use in online (or phone) fraud is via [[phishing]] scams, which also will result in the capture of the CSC codes for the compromised credit card. This fact of life has reduced the real-world effectiveness of the CSC codes as an anti-fraud device.
