Card Security Code (also referred to as CVV2, CVC or CID) is an authentication mechanism created by card companies to help reduce fraud with online transactions. It requires the card holder to have the card physically in hand in order to enter three or four digits found printed on the card itself.
Where do I find the numbers?
On Visa, MasterCard and Discover credit cards, the number is located on the back of the card in the signature area. The number is always three digits and is sometimes preceded by the card number or the last four digits of the card number. On American Express cards, the four-digit number is located on the front of the card, just above the card number, usually on the right.
Why do you require this?
Online credit card fraud is on the rise. Requiring these codes is one more way we can ensure our patron’s security.
