Casino Chip Tray Fraud Detection With 3D and RFID Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing casino fraud detection systems face challenges in accurately determining the total amount of chips due to blind spots and overlapping chips, and cannot detect sophisticated fraud methods like card squeegee or dealer-player conspiracies, leading to undetected errors in chip collection and redemption.
Innovation Solution
A fraud detection system using a game recording apparatus, image analyzing apparatus, and control device with artificial intelligence and deep learning capabilities to analyze chip positions, types, and numbers, and determine win/lose results, enabling accurate detection of chip movements and fraud through image analysis and comparison with statistical data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surveillance cameras are used to monitor chip movements, then fraud detection capability is improved, but blind spots and overlapping chips cause measurement precision to deteriorate
Solution Approach 1:
The system transitions from two-dimensional image analysis to three-dimensional point cloud analysis by converting camera images into spatial point clouds. This dimensional transformation enables accurate chip recognition even when chips overlap or are in blind spots, as the point cloud data captures depth information and spatial relationships that 2D images cannot resolve.
Solution Approach 2:
The system introduces RFID tags as an intermediary element attached to each chip. These tags enable wireless communication between the chip and the reading device, providing a reliable method to identify and track individual chips regardless of their visual occlusion or position in blind spots, thereby complementing the visual monitoring system.
2Measurement precision
If RFID tags are attached to each chip for recognition, then chip identification accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The RFID reading device is integrated into the existing gaming table infrastructure, serving multiple functions: it reads RFID tags on chips, tracks chip movements, and communicates with the fraud detection system. This multi-functionality reduces overall system complexity despite the addition of RFID technology, as the reading device becomes a versatile component rather than a dedicated single-purpose device.
3Device complexity
If manual monitoring of chip collection and redemption is performed, then system complexity is reduced, but fraud detection reliability deteriorates due to human error and sophisticated fraud methods
Solution Approach 1:
The system implements continuous feedback loops where the fraud detection system constantly compares the expected chip movements (based on game rules and win/lose results) with the actual chip movements detected by cameras and RFID readers. When discrepancies are detected, the system generates alerts and can automatically intervene, providing real-time feedback that enhances reliability without requiring complex manual monitoring procedures.
Solution Approach 2:
The system enables self-service fraud detection by automatically analyzing chip movements, comparing them against game rules, and identifying fraudulent activities without human intervention. The automated analysis of point cloud data and RFID information allows the system to detect sophisticated fraud methods such as card squeegee and dealer-player conspiracies, reducing reliance on manual monitoring while maintaining high reliability.

AI summary
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.
