the management controller is configured to manage the revenues and expenses of the casino based also on an amount of the decrease of the gaming chips in the gaming chip tray due to the buying of the gaming chips at the gaming table.
4. The management system according to claim 2 , further comprising:
a vault configured to hold the gaming chips at the cashier; and
a vault RFID reader configured to read the RFID tag of the gaming chips held in the vault,
wherein the management controller is further configured to record the IDs of the gaming chips held in the vault, together with their location information, in the database based on a reading result of the vault RFID reader,
wherein the buying and selling of the gaming chips at the cashier increases or decreases the gaming chips held in the vault,
wherein the management controller is configured to record the IDs of the gaming chips together with their location information in the database based on a reading result of by the vault RFID reader, and
wherein the management controller is configured, when there is a change in a presence of the gaming chips in the vault, store the IDs and the location information in the database in association with the ID and the location information based on a result of the reading result of the vault RFID reader, and
wherein the management controller is configured to manage the revenues and expenses of the casino based on an amount of increase or decrease of the gaming chips in the vault based also on the IDs and the location information of the gaming chips stored in the database.
5. The management system according to claim 1 , wherein the location information indicates: a vault in the cashier; the gaming chip tray; in transit between the cashier and the gaming chip tray; or held by a game participant.
