WHAT IS THE CARD SECURITY CODE?
The Card Security Code (CSC) provides added security when you use your credit card on the Internet or over the telephone. The number appears only on the card itself, and not on receipts or statements.
HOW DOES IT PROVIDE ADDED SECURITY?
This helps ensure that anyone making a payment over the Internet or telephone has the card in their physical possession, and is not using a stolen credit card number.
