CVV
Card Verification Value: Three or four digits printed on the back of a credit card that identify the credit card holder. For AVS transactions, the merchant can request a CVV number from the customer, which is compared to the CVV that’s on file with the credit card company to verify the card holder’s identity. CVV processing doesn’t affect whether the charge is approved, but it does reduce credit card fraud when the physical card isn’t available to swipe through an MSR device (e.g., as with telephone orders).
