RFID Table System for Real-Time Chip Inventory Variance Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gaming systems face challenges in real-time tracking and correction of out-of-balance events at table games, leading to significant revenue losses due to incorrect collection or payment of wagering chips, as dealers often fail to rectify mistakes promptly, resulting in complexities and inaccuracies when determining the source of variances after game events are finalized.
Innovation Solution
The implementation of an RFID-enabled table system that tracks RFID-enabled game elements, such as chips, in real-time, using antennas and processors to detect variances and alert personnel, allowing for timely correction of out-of-balance events by providing specific information to dealers during the game, thereby preventing revenue losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual tracking of wagering chips is used, then device complexity is reduced, but measurement precision and reliability of chip inventory tracking deteriorate
Solution Approach 1:
The patent replaces manual mechanical tracking methods with RFID (radio frequency identification) technology. RFID tags are embedded in wagering chips, and RFID readers at the table automatically detect and track chip locations, denominations, and transactions without physical intervention. This substitution dramatically improves measurement precision of chip inventory while the automated nature of RFID systems actually reduces operational complexity despite adding technological components.
2Reliability
If real-time RFID tracking is implemented, then reliability of detecting out-of-balance events is improved, but use of energy and device complexity increase
Solution Approach 1:
The RFID tracking system operates periodically rather than continuously. The system triggers RFID scans at specific events such as when a chip is placed on the table, when a transaction occurs, or at predetermined intervals. This periodic operation maintains high reliability for detecting out-of-balance events while significantly reducing energy consumption compared to continuous monitoring. The system only activates RFID readers when needed for tracking purposes.
3Productivity
If continuous monitoring of chip transactions is performed, then productivity of error detection is improved, but loss of time in game play increases
Solution Approach 1:
The system implements feedback mechanisms where RFID readers automatically detect chip transactions and provide real-time feedback to both the table management system and the dealer. When an out-of-balance event is detected, the system immediately alerts personnel through visual or audible signals, enabling rapid correction without interrupting the overall game flow. This feedback loop maintains high productivity in error detection while minimizing game play loss by allowing games to continue uninterrupted.
4Measurement precision
If RFID tags are embedded in all wagering chips, then measurement precision of chip identification is improved, but manufacturing precision requirements and cost increase
Solution Approach 1:
The RFID tags are designed with universal compatibility across all chip denominations and types used at the table. A single RFID reader system can identify and track chips of various values, colors, and designs without requiring different detection mechanisms. The RFID tags are embedded using standardized procedures that work across different chip manufacturers, reducing manufacturing precision requirements while maintaining high identification accuracy through the universal RFID protocol.

AI summary
In accordance with some embodiments, an RFID-enabled table game system provides for determining whether there is a variance between an expected balance of inventory and an actual balance of inventory in a game element container. If a variance is detected, the RFID-enabled game system may identify at least one characteristic associated with an RFID-enabled game element that is determined to be a source of the variance (e.g., a player position at which the RFID-enabled game element had last been detected, a denomination or value of the game element, and/or an identifier associated with the game element). In some embodiments, an alert may be output to game provider personnel (e.g., a dealer of a card game) at the end of a game play when such a variance is detected, thus allowing the variance to be corrected in an efficient and timely manner.
