What is a CVV digit test for security?

A CVV digit test is a validation check used during authorization to confirm the card verification value supplied by the customer matches the issuer's records. Legitimate testing uses sandbox credentials and test cards, never real customer card data, to confirm checkout and fraud rules behave correctly.
