A gaming table with an upper surface that includes a gaming chip placement area and a lower surface opposite the upper surface is provided. The gaming table also includes a housing coupled to one of the upper surface and the lower surface of the gaming table, an antenna coupled to the housing, wherein the antenna is configured to form an electromagnetic field that defines a zone of communication in which a gaming chip including a radio frequency identification (RFID) tag can be read. The gaming table also includes a substantially-contiguous highly permeable magnetic material layer coupled to the antenna, the highly permeable magnetic material layer defining an outermost boundary of the zone of communication of the antenna, such that a strength of the electromagnetic field at any region beyond the defined boundary of the zone of communication is below a threshold level for communication with an RFID gaming chip, and a reading device coupled to the housing, wherein the RFID reading device is configured to read data transmitted by an RFID gaming chip when the RFID gaming chip is in the zone of communication. 0,, 0 w z0 3: |
