RFID Casino Token Ownership Tracking for Counterfeit Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game token management systems fail to record and determine the owner information of game tokens, particularly those with abnormal usage histories, allowing counterfeit or improperly used tokens to go undetected in casinos.
Innovation Solution
A game token management system that includes RFID-equipped tokens, a chip placement area, a chip reader, and a controller to associate owner information with the tokens, enabling traceability and detection of abnormal usage by linking bet and payout chips through a database.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional RFID game tokens are used to determine authenticity, then counterfeit token detection is improved, but owner information tracking capability deteriorates
Solution Approach 1:
The patent embeds an RFID tag within the game token structure, creating a nested configuration where the RFID tag (containing owner information) is integrated inside the game token. This allows the token to maintain its primary gaming function while simultaneously carrying additional owner tracking information through the embedded RFID component.
Solution Approach 2:
The RFID tag serves as an intermediary carrier that bridges the gap between the physical game token and the digital owner information database. By reading the RFID tag, the system can indirectly access and verify owner information without requiring direct interaction with the token's physical properties or manual tracking.
2Reliability
If RFID reading is used to verify game tokens, then counterfeit detection is improved, but usage history tracking deteriorates
Solution Approach 1:
The RFID tag acts as an intermediary that carries usage history information between the game token and the external database. Each time the token is used or transferred, the RFID tag's data is updated and can be read to verify the complete usage history, maintaining both verification capability and historical tracking.
Solution Approach 2:
The system implements feedback by continuously reading and updating the RFID tag information whenever the game token is used, transferred, or redeemed. This creates a closed-loop information system where usage history is automatically recorded and can be verified against the database to detect abnormal patterns.
3Ease of manufacture
If simple RFID tags are attached to game tokens, then manufacturing ease is improved, but owner information management capability deteriorates
Solution Approach 1:
The RFID tag is integrated within the game token during the manufacturing process, allowing both components to be produced together in a single manufacturing flow. This nested approach eliminates the need for separate attachment steps while enabling sophisticated owner information management capabilities through the RFID technology.
Solution Approach 2:
The game token is designed with multi-functionality by incorporating the RFID tag, allowing it to serve both its traditional gaming purpose and its new function as an owner information carrier. This universal design enables the same token structure to handle multiple tasks: gaming, tracking, verification, and historical recording.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively tracks and manages token ownership, preventing the use of tokens with abnormal histories by associating owner information, thereby enhancing security and preventing fraud in casino gaming.
Implementation Method 1
a game token to which individually identifiable RFID is attached
Data Source
AI summary
A management system for managing game token includes, a holder identification device for identifying the holder of the game token by referring to a memory that stores the holder of the game token when a game token s used, a player identification device for identifying the player who used the game token when the game token is used, and a controller that generates an error signal when the holder identified by the holder identification device and the player identified by the player identification device do not match for the game token that have been used.
