When we make purchases online, generally, the last piece of information that we are asked to provide is the card verification value of our card, best known simply as the CVV number.

It’s the code written on the back of our card, usually three to four digits, and it’s goal is to prevent fraud transactions from taking place. Basically, it’s an additional security measure when your card cannot actually be swiped by the seller.
