I used to do this, until I started having my card refused by the robots at
large chains like Best Buy. Seems corporate policy mandates the card must be
signed, no exceptions. My solution was to sign it with a fat-tip sharpie.
The resulting mess has the same SHAPE as my signature, but isn't clear
enough to learn to forge from.
