Abstract

A gaming table provides for use of RFID technology to track chip movement on a table game and to infer an association between a wager and a player position based on a chip identifier of a chip placed on a particular position of the table. In some embodiments, previous position history of the chip is also taken into account in determining a player position associated with a wager.
