Claim:
1. A system for locating gaming tokens on a gaming table, comprising: a first set of antennas oriented in a first direction, wherein the first set of antennas defines a betting area of the gaming table, and wherein the first set includes a first subset of antennas and a second subset of antennas, wherein the first subset and the second subset are overlapping; a second set of antennas oriented in a second direction that differs from the first direction, wherein the first set and the second set are overlapping, wherein the second set includes a third subset of antennas and a fourth subset of antennas, wherein the third subset and the fourth subset are overlapping; and a control circuit, coupled to the first and second sets, that is configured to selectively energize the first and second sets, that is configured to receive a first plurality of signal strengths resulting from reading a radio frequency identification (RFID) gaming token in the betting area according to the first set being selectively energized, that is configured to receive a second plurality of signal strengths resulting from reading the RFID gaming token in the betting area according to the second set being selectively energized, and that is configured to determine a location of the RFID gaming token in the betting area by comparing the first plurality of signal strengths and the second plurality of signal strengths.
