You can reduce fraudulent charges on a saved credit card by requiring the cardholder to re-enter their card verification code (CVC). Recollecting the CVC can help reduce fraud because correctly entering the CVC requires that the customer has the physical card in-hand. In addition to fraud prevention, the presence of correct CVCs has also been shown to slightly improve authorization rates.

Additional Information

• It is possible for charges to be approved by a customer's bank despite there being a CVC mismatch. To block charges that fail the CVC check, you can use Radar's built-in rule to block charges that fail the CVC verification.
