This is security-protection for your credit card. The Card Verification Number (often referred to as CVV) is a three- or four-digit number imprinted in the cards. It is used to assist in verifying that you are actually in possession of the card in question and helps to protect you against fraudulent purchases.
On a Visa, MasterCard, or Discover Card, look for the 3-digit number printed on the signature panel on the back of your card.
On American Express Cards, look for the 4-digit number printed above your account number on the face of your credit card.
