The Card Verification Code (CV2) also called the Card Security Code, is the 3-4 digit security number placed at the back of the card. It is often used to authenticate a consumer physically owns the card.
After a payment has been processed successfully, Judopay provides you with a card and consumer token.
These tokens can be stored and used with the original Consumer Reference to process future payments on behalf of that consumer. This means by processing a token payment, returning consumer's will only need to enter their CV2 to complete the transaction.
