Your CVV helps retailers verify that you have physical possession of the credit card you are paying with — whether online or on the phone — and adds an extra layer of security for your account.

With more than 150 million merchant locations worldwide, Visa’s extensive network ensures consumers can use Tap to Pay Visa Gift Cards anywhere contactless Visa payments are accepted.

You give the credit card number, and the restaurant employee asks for the expiration date and the CVV. This is easy to answer, of course, if you’re looking at the actual credit card.
