Biometric Card

Encodes a players identity on the card, right click another player, or shift slick to set yourself. If you encode the same player twice, it will clear the card. A Cleared card represents other users as the "default".
When the Biometric Card has been encoded it will show a Identicon for the user so you can tell cards apart, each card for the user will have the same Identicon.
