Abstract

A fraud detection system which detects fraud in a game of performing collection and redemption of chips in accordance with a win or lose result includes a camera which captures an image of chips contained in a chip tray of a dealer, an image analyzing apparatus which analyses the image captured by the camera to detect an amount of the chips contained in the chip tray, a card distribution device which determines a win or lose result of a game, and a control device which compares the win or lose result of the game and the amount of the chips contained in the chip tray before and after collection and redemption of the chips to detect fraud.

14. The game management system of claim 13 , wherein the card is a member identification card.

15. The game management system of claim 1 , wherein the at least one processor is configured to determine the result of the game based on information regarding types of game cards the at least one processor senses to be drawn during the game.

16. The game management system of claim 15 , wherein the at least one processor includes a processor of an electronic card distributor, the processor of the electronic card distributor being configured to sense the information regarding the types of the game cards as the game cards are withdrawn from the electronic card distributor.

17. A game management system comprising:

a data storage device;

at least one sensor; and

at least one processor;

wherein:

the at least one processor is configured to:

identify, based on output of the at least one sensor:

presence of a player that is associated in the storage device with a respective one of a plurality of player identification numbers;

transfer, by the player whose presence has been identified and to a dealer, of at least one of (a) one or more chips and (b) one or more currency units; and

transfer, by the dealer and to the player, of one or more chips; and

update chip information of the player in a record in the storage device, which record is associated in the storage device with the player; and

the update is performed based on the identified transfers.

18. A game management system comprising:

a data storage device;

a camera; and

at least one processor, wherein the at least one processor is configured to:

perform image analysis of one or more images output by the camera based on the camera sensing an area of a gaming table, the at least one processor thereby:
