Card payments company Visa has launched a feature that allows users to carry out online transactions without the need to punch in the cardholder verification value (CVV), if the card has been tokenized.The CVV-free feature launched in India is aimed at making the online transaction process smoother. The merchants who adopt this will not have to ask customers for their CVV every time they do a domestic transaction. They will be verifying this three-digit number on the back of the card only once, at the time of tokenizing the card.
