Casino Table Chip Tracking With RFID-Image Player Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game monitoring systems for real table games struggle to accurately associate gaming chips with the correct players, particularly in cases where the owner of the chip does not match the identified player, leading to potential illicit activities and inaccurate patron ratings.
Innovation Solution
A game monitoring system that uses imaging and RFID technology to identify gaming chips and players, associating chip IDs with player images, and includes a comparing mechanism to detect mismatches, allowing for real-time corrections and updates to ensure accurate associations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID technology is used to identify gaming chips and imaging technology is used to identify players, then measurement precision of player-chip association is improved, but device complexity increases due to multiple sensing systems and data processing requirements
Solution Approach 1:
The system divides the monitoring function into separate modules: RFID reading means for chip identification, imaging means for player identification, player detecting means for player presence detection, chip detecting means for chip location tracking, first associating means for initial player-chip association, and second associating means for verification. This segmentation allows each module to specialize in one function, improving overall measurement precision while managing complexity through modular design.
Solution Approach 2:
The control device acts as an intermediary that receives data from multiple independent sensing systems (RFID, imaging, player detection, chip detection) and performs data processing and association. This intermediary coordinates the information flow between different subsystems, enabling accurate player-chip association without requiring direct integration between all components.
2Reliability
If multiple detection and association mechanisms are implemented, then reliability of game monitoring is improved, but device complexity increases due to additional comparing and updating means
Solution Approach 1:
The system implements feedback through the comparing means that continuously compares the player-chip association from the first associating means with the player identity detected by the player detecting means. When a mismatch is detected, the updating means provides corrective feedback to update the association. This feedback loop ensures high reliability by continuously verifying and correcting associations without requiring permanent complex hardware additions.
Solution Approach 2:
The association data is not static but dynamically updated based on real-time detection and comparison. The updating means allows the system to adapt and correct associations during gameplay, making the monitoring system flexible and reliable rather than rigid. This dynamic approach improves reliability without permanently increasing hardware complexity.
3Measurement precision
If real-time imaging and RFID reading are performed for every betting action, then measurement precision of betting monitoring is improved, but loss of time increases due to frequent data processing operations
Solution Approach 1:
The system performs preliminary identification of players and gaming chips before betting actions occur. The imaging means and RFID reading means are ready to quickly capture and process data when betting actions happen, rather than initiating full processing sequences during the betting action itself. This preliminary preparation reduces the time loss during actual betting monitoring while maintaining high measurement precision.

AI summary
A game monitoring system comprises a chip ID identifying portion configured to identify, when a gaming chip to which a chip ID is given is in a betting area on a game table, the chip ID of the gaming chip; a first camera configured to image a player playing a game at the game table and the gaming chip on the game table to generate an image; a player detecting portion configured to detect the player from the image; a chip detecting portion configured to detect the gaming chip from the image; a first associating portion configured to associate the player detected by the player detecting portion with the gaming chip detected by the chip detecting portion as the player who bet the gaming chip; a second associating portion configured to associate the chip ID of the gaming chip identified by the chip ID identifying portion with the player associated with the gaming chip by the first associating portion; and a recording portion configured to record a pair of the chip ID of the gaming chip and an image of the player associated with the chip ID of the gaming chip by the second associating portion.
