1. A playing card reader, comprising:
- a housing having a receptacle sized to receive a plurality of playing cards;
a transmitter received in the housing;
a receiver received in the housing;
at least a first antenna electrically coupled to at least one of the transmitter and the receiver, the first antenna positioned to electro-magnetically interrogate at least some of the playing cards; and
a computer-readable medium storing a mapping that uniquely identifies playing cards based on a random distribution of conductive material carried by each of the playing cards, wherein at least one of a number of aspects of the conductive material carried by each playing card corresponds to a respective rank or suit of the respective playing card, the number of aspects of the conductive material including the number and size of the conductive material.

Abstract
Playing cards carry conductive material which may be wirelessly interrogated via radio frequency transmission to identify a rank and/or suit for monitoring a card game. Chips carry conductive material which may be wirelessly interrogated via radio frequency transmission to identify a value for monitoring wagering in a card game.

7. A system for wirelessly monitoring wagering and play of a playing card game at a gaming table using playing cards and wagering chips each bearing conductive material, the system comprising:
-
a card reader having a wireless transmitter and receiver coupled to at least a first antenna to electro-magnetically interrogate playing cards; a chip reader having at least one wireless transmitter and receiver coupled to a plurality of antennas positioned proximate to respective wagering placement areas to electro-magnetically interrogate wagering chips placed at the wager placement areas, if any; and a computing system coupled to receive data from both the wireless card reader and the wireless chip reader, the computer system including a computer-readable medium storing a mapping that uniquely identifies playing cards based on a random distribution of conductive material carried by each of the playing cards, wherein at least one of a number of aspects of the conductive material carried by each playing card corresponds to a respective rank or suit of the respective playing card, the number of aspects of the conductive material including the number and size of the conductive material. - View Dependent Claims (8, 9, 10)
