Why is the CVV code needed for online bill payment?

The Credit Card Validation (or Verification) Value is the extra three- or four-digit code that appears on your credit card. This extra security measure ensures you have physical possession of the credit card. At this time, eBill requires the three-digit CVV code for Discover card users only. It appears after your credit card number on the back of your card in the signature area.
