What is the Security Code?
The credit card Security Code, also called the Bank code or the Card Identification Number (CID), is a special security code feature on the American Express, Diner's Club, Discover, MasterCard or Visa credit card.
By requiring the Security Code to be entered with the customer's credit card, you are verifying that the order is being placed by the card holder. The Security Code offers protection to the card holder as well. The Card Identification Number (CID) is not raised, so they are not scanned into standard credit card readers. In theory, these numbers are only visible to the card holder.
