their three-digit "security codes"

On the merchant side, we were always told that it was not permitted to store the CVV/CVV2 in a database, precisely for this reason.

We do not store it and never have. No merchant should. The only thing that needs to be stored is the message from the bank indicating whether or not the code matched.
