Credit Card Verification
For VISA, MasterCard and Discover, the number is the last 3 digits (usually set off by themselves) on the Signature Panel on the back of the card.
For American Express, look for a 4-digit number printed above your account number on the face of the card.
What is the purpose of this number?
Since there is no "signature" provided with an on-line credit card payment, this number is used to verify that a customer actually has the credit card in their possession. At FSJ we are committed to protecting our guests and members through the use of a secure web site and verification using the CCV.
