If you select this option, the CVV field will be a required field that customers must enter to complete the checkout process. If the "CVV Required" checkbox is not checked, customers can choose to enter or not to enter the CVV number in this field during checkout.
To make CVV a required field:
Note: You must have your online payment processing set to perform real-time authorizations in order to use AVS and CVV Rules to flag orders based on response codes as part of Risk Tools. Without real-time authorization, Risk Tools cannot check the address and card verification value provided by customers during checkout. View instructions for enabling real-time authorization of orders.
Your customers will then need to supply a card security number when using Visa, MasterCard, or Discover as their payment option in order to submit their order. The number entered by the customer will then be checked using the CVV Rules you have set for your store and the order will be accepted, or "flagged" with a "pending review" status.
