Casino Table Token Management via Image and RFID Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RFID-based systems for detecting fraud game tokens in casinos face challenges in recognizing tokens without RFID tags or with broken RFID tags, and they struggle with reading individual side bets and increasing costs due to embedded RFID antennas.
Innovation Solution
A management system for table games that uses a combination of image analysis from cameras and RFID reading to identify and count game tokens, detect fraud or faulty tokens, and manage bets across multiple areas, including player, banker, and side-bet areas, while minimizing the number of RFID antennas required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID antennas are embedded in each bet area to read individual side bets, then reading accuracy and bet area coverage are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
A single RFID antenna is designed to perform multiple functions: reading game tokens from multiple bet areas (player area, banker area, side bet areas) and identifying both main bets and side bets. This multi-functional antenna replaces the need for separate antennas in each bet area, reducing device complexity while maintaining reading accuracy through strategic positioning and advanced signal processing algorithms.
Solution Approach 2:
The system transitions from a two-dimensional planar distribution of multiple antennas across the table surface to a three-dimensional solution using a single strategically positioned antenna that leverages spatial signal propagation. The antenna is placed at an optimal location and angle to cover all bet areas, utilizing the third dimension (vertical positioning and angular orientation) to achieve comprehensive coverage without multiplying antenna quantity.
2Adaptability or versatility
If RFID antennas are embedded in each bet area to read individual side bets, then side bet reading capability is improved, but manufacturing cost increases
Solution Approach 1:
The single RFID antenna is engineered to universally read all types of game tokens across all bet areas including player bets, banker bets, and side bets. This universal reading capability eliminates the need for multiple specialized antennas, significantly reducing manufacturing costs while maintaining full adaptability to read individual side bets when they are placed.
Solution Approach 2:
The system uses image recognition technology to create a visual copy or representation of the betting table layout, including side bet positions. The image analyzer processes camera images to identify side bet areas and correlates them with RFID readings, enabling side bet reading capability through software-based mapping rather than hardware multiplication.
3Reliability
If player area and banker area are widely separated to accommodate RFID reading, then reading reliability is improved, but game table layout flexibility decreases
Solution Approach 1:
The system achieves reliable RFID reading across closely spaced player and banker areas by utilizing three-dimensional antenna positioning and signal processing. Instead of requiring wide horizontal separation, the single antenna is strategically positioned in the vertical dimension and angled to optimize signal coverage across the table, allowing flexible layout arrangements while maintaining reading reliability.
Solution Approach 2:
The patent replaces the mechanical constraint of physical antenna separation with an electronic/software-based solution. Advanced signal processing algorithms and image recognition technology compensate for the reduced physical distance between reading zones, allowing the system to maintain high reading reliability without requiring wide separation between player and banker areas.

AI summary
A management system for a table game includes a function in which the type and the number of bet game tokens are determined independently in bet areas including at least a player bet area and a banker bet area based on an image analysis result by an image analyzer and it is determined whether the total amount of money or the total number of game tokens every sitting number or in each of the read areas based on the image analysis result by the image analyzer is matched with the total amount of money or the total number of game tokens every sitting number or in each of the read areas based on the read result by a chip reader.
