1. A reading system for game tokens, comprising:
a storage section that is provided in a game table and extending in a plane, for storing a game token equipped with a radio-frequency identification (RFID) tag,
wherein the RFID tag stores at least an ID assigned to the game token;
a reading device having a plurality of antennas, each configured to generate an electromagnetic wave for reading the RFID tag of the game token stored in the storage section,
wherein the plurality of antennas corresponds to a plurality of partial areas of the storage section so that the electromagnetic waves of the plurality of antennas do not read the RFID tag of the game token placed in an area other than the storage section where the game token is stored, and
wherein the plurality of antennas is arranged to have overlapping portions in respective reading ranges of the antennas such that when the game token is stored in a portion of the storage section corresponding to an overlapping portion, the RFID tag can be read in duplicate by multiple antennas, and;
a control unit configured to:
identify the ID assigned to the game token stored in the storage section, and
determine that there is one game token in the storage section with the ID assigned when the RFID tag on the same game token is read in duplicate by the electromagnetic waves generated by multiple antennas.
