Abstract
When RF signals of a plurality of RFID tags installed in a plurality of casino chips are received through a plurality of reader antennas, a system for managing casino chips using RFID (radio frequency identification) estimates an angle of arrival of the received RF signals, calculates the number and positions of the plurality of casino chips by using the received RF signals and each estimated angle of arrival, and manages the plurality of casino chips by using the number and the positions of the plurality of casino chips.
