11/27   What's the purpose of having/requesting the three-digit
        "security code" on the back of credit cards? I don't see
        how it makes transactions more secure; anyone tapping into
        a phone call or computer network can pick up that number as
        easily as the CC# itself and expiration date.
        \_ It does prevent dumpster divers (aka, employees) from taking
           all the necessary information off of the carbon copy.  In stores,
           you are never asked for the extra 3 digits, as they can see you
           have the card, but online, it is supposed to prove that you are
           holding the card.  But, if you can monitor the communications,
           you can do anything you want.
