What is the card security code?
This is a security measure we require for all transactions. Since the card security code is a number is listed on your credit card, but is not stored anywhere, the only way to know the correct number for your credit card is to physically have possession of the card itself. All VISA, MasterCard and American Express cards made in America in the past 5 years or so have a security code number, while those in Europe and Asia will be joining this program shortly*** (please see bottom).
A Card Security Code is a special security code feature on your American Express, Discover, MasterCard or Visa credit card. The codes are not raised, so they are not scanned into standard credit card readers. In theory, these numbers are only visible to you. When you give your code to a merchant, you assist the merchant in verifying that the order is being placed by you, the card holder. The Muscular Dystrophy Association requires you to enter your Card Security Code whenever you make an online donation to help us detect fraudulent use of your card before your account is charged. This simple step allows us to greatly enhance the safety and security of our ordering process.
