It is simply a method to increase the likelihood that the human at the other end of the transaction actually has the phyiscal card. Storing CSC/CVV's is illegal. I believe that even places like VeriSign do not store the CSC. Really, the only information you need to run a credit card is the number and expiration date (although you will pay a higher %). DanB
