 A card security code (CSC) (also termed card verification code (CVC) and card verification value (CVV/CVV2)) is also associated with the virtual credit card; as in standard credit cards, a CVV is used in virtual credit cards to establish card ownership by the buyer and to authorize transactions.Virtual credit cards often expire much sooner than physically issued credit cards, e.g., 60 days.As security is a primary reason for VCC usage, rapid turnover of VCNs prevents funds from being compromised for long periods of time.
