Casino Token RFID Tracking for Holder Anomaly Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current casino systems lack an efficient method to manage game tokens, particularly in identifying abnormalities such as unauthorized possession, excessive token holdings, and tracking token history, which can lead to fraud and mismanagement.
Innovation Solution
A management system that utilizes RFID tags with both non-rewritable and rewritable areas to store information, including location and ownership data, allowing for real-time tracking and abnormality detection through a network of readers and controllers, enabling accurate monitoring and control of game tokens across the casino facility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual tracking of game tokens is used, then system complexity is reduced, but measurement precision and reliability of token management deteriorate
Solution Approach 1:
The patent replaces manual mechanical tracking with an automated RFID-based electronic system. RFID tags embedded in game tokens enable automatic identification and tracking by readers positioned at game tables, eliminating the need for manual record-keeping while significantly improving tracking precision and reliability.
Solution Approach 2:
The patent creates information copies of game tokens through RFID tags that store token identification data. These electronic copies allow multiple readers to simultaneously track the same token across different locations without physical interference, enabling precise tracking while maintaining system efficiency.
2Reliability
If real-time monitoring of all game tokens is implemented, then reliability of fraud detection is improved, but use of energy and device complexity increase
Solution Approach 1:
The system implements periodic monitoring where RFID readers at game tables automatically detect and track tokens as they are placed or removed. This periodic action triggered by token movement provides reliable fraud detection capability while minimizing continuous energy consumption compared to constant monitoring of all tokens system-wide.
Solution Approach 2:
The system performs preliminary actions by registering tokens with RFID tags before they enter gameplay and maintaining records of token issuance. This preliminary tracking establishes a baseline that enables reliable fraud detection without requiring intensive real-time monitoring of every token movement throughout the casino.
3Measurement precision
If comprehensive holder information is stored in the database, then measurement precision of abnormality detection is improved, but loss of time for data processing increases
Solution Approach 1:
The system performs preliminary actions by pre-registering token holder information, transaction history, and game results in the database before abnormality detection is needed. This pre-established data foundation enables rapid abnormality detection by allowing the management device to quickly compare current token movements against historical patterns without extensive real-time data processing.
Solution Approach 2:
The patent replaces time-consuming manual verification processes with automated electronic database queries. The management device automatically compares RFID-identified token movements against stored holder information and detects abnormalities in real-time, significantly reducing data processing time while maintaining high detection precision.

AI summary
A management system for game tokens includes a player identification device installed at a predetermined location in a casino facility to identify a player and thereby identify that the player is at the predetermined location, a database storing information on holders of game tokens, and a management device referring to the database to determine whether there is an anomaly in the holder information, wherein the management device determines whether or not there is an abnormality in the combination of the predetermined location where the player identified by the player identification device is located and the holder information stored in the database.
