RFID Game Token Tracking for Bet and Payout History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game token management systems fail to record and verify the ownership history of game tokens, allowing counterfeit or improperly used tokens to go undetected, as they only authenticate the token itself and not its usage history.
Innovation Solution
A game token management system that includes RFID-tagged tokens with individually identifiable chips, a chip reader, and a controller to associate owner information with bet and payout chips, enabling traceability and detection of abnormal usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional RFID authentication is used to verify game token authenticity, then counterfeit tokens can be detected, but tokens with abnormal usage history cannot be identified
Solution Approach 1:
The system segments the information verification process into two distinct layers: (1) token authenticity verification through RFID authentication, and (2) usage history verification through owner information tracking. This segmentation allows each verification aspect to be handled independently while collectively providing comprehensive token validation.
Solution Approach 2:
The system introduces owner information as an intermediary element that bridges the gap between token authentication and usage history tracking. By associating owner information with the token and verifying it during transactions, the system indirectly captures and validates usage history without directly storing it in the token.
2Loss of information
If owner information tracking is implemented for all tokens, then usage history can be monitored, but system complexity increases
Solution Approach 1:
The owner information mechanism serves multiple functions simultaneously: it tracks token ownership, verifies usage history, prevents counterfeit usage, and enables audit trails. This multi-functionality reduces the need for separate systems for each purpose, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The system enables self-service tracking where the owner information is automatically associated with tokens during legitimate transactions without requiring manual intervention. The verification process automatically checks owner information against the token, reducing operational complexity while maintaining comprehensive tracking.
3Reliability
If detailed tracking of bet chips and payout chips is implemented, then abnormal usage can be detected, but processing time increases
Solution Approach 1:
The system performs preliminary association of owner information with tokens at the point of payout, before the token enters circulation. This advance preparation means that during subsequent betting and verification processes, the system only needs to check pre-associated owner information rather than tracking from scratch, reducing processing time while maintaining detection capability.
Solution Approach 2:
The system implements selective verification that skips detailed tracking for routine legitimate transactions while focusing on detecting abnormal patterns. By using owner information as a quick check mechanism and only initiating detailed tracking when discrepancies are detected, the system reduces average processing time while maintaining high reliability for abnormal usage detection.

Data Source
AI summary
A controller of the table game management system is configured to be able to recognize that a bet chip bet by a winning player and a payout chip paid to the winning player are transferred outside a chip placement area, and associate, in a database, ID information of the payout chip with ID information of the bet chip transferred outside the chip placement area at the same timing as the payout chip, and includes a function to associate, in the database, ID information held by RFID of the payout chip with information about an owner of the bet chip indicated by RFID of the bet chip.
