What is a CVV (Card Verification Value) code and what it is used for?

 What is referred to by the term CVV or sometimes called Card Security Code?
CVV (Card Verification Value ) refers to the printed, not imprinted, number on your Visa, MasterCard, American Express, or Discover Card.

Visa, MasterCard, and Discover cardholders can find their CVV or sometimes called Card Security Code (CSC) in the signature area on the back of the credit card. It is the three-digit number printed immediately following the signature stripe. American Express cardholders can find their four-digit CSC printed above and to the right of the imprinted card number on the front of the card.

In Sphere, we only require and verify the CVV when submitting transactions through the frontend of a website. When entering transaction through the backend (bookkeeping), sphere does not require the CVV number.
