Gaming Currency Inspection Using RF and Photosensor Count Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In game houses like casinos, there are challenges in accurately monitoring and managing gaming currencies due to issues such as incorrect reading of IC tags, blind spots from camera views, and advanced fraud methods that evade simple detection.
Innovation Solution
An inspection system that uses RF tags embedded in gaming currencies, combined with a housing unit, RF reading devices, and alarm systems to detect discrepancies in the number of gaming currencies, and an integrated management system that employs cameras, image analysis, and artificial intelligence to monitor and manage gaming currencies effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RF tags are used for counting gaming currencies, then reading accuracy is improved, but blind spots from camera views still cause detection errors
Solution Approach 1:
The system merges two different detection methods: RF tag reading and camera-based image analysis. The RF reader accurately counts gaming currencies through electromagnetic field detection, while the camera provides visual verification and detects physical characteristics. By combining these methods, the system overcomes the blind spot limitation of cameras and achieves comprehensive monitoring without losing detection coverage.
2Reliability
If multiple detection methods are combined, then detection reliability is improved, but system complexity increases
Solution Approach 1:
The control device serves multiple functions: it processes RF tag data for counting, analyzes camera images for visual verification, compares results from both methods, and triggers alarms when discrepancies are detected. By making the control device multi-functional, the system integrates multiple detection methods without proportionally increasing overall system complexity.
Solution Approach 2:
The system implements feedback by continuously comparing results from RF reading and camera-based detection. When the counts from both methods match, the system confirms accurate detection. When discrepancies occur, the system triggers an alarm and can re-run detection routines. This feedback mechanism improves reliability by validating results through cross-verification.
3Productivity
If real-time monitoring is implemented, then fraud detection speed is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system performs detection at periodic intervals or at specific trigger events (e.g., when gaming currencies are added to or removed from the tray). The RF reader and camera activate periodically or on-demand, comparing results to detect fraud. This periodic operation maintains real-time fraud detection capability while significantly reducing energy consumption compared to continuous monitoring.

AI summary
When an unfair gaming currency is delivered to a dealer from a player, the currency is detected as unfair. The inspection system for inspecting the gaming currency, in which an RF tag is built, comprises: a gaming currency tray for housing the gaming currencies of the dealer in a casino game; an RF reader for reading the RF tags of the plural gaming currencies housed in the gaming currency tray; plural photosensors for detecting at least the number of the plural gaming currencies housed in the gaming currency tray at a constant time interval or always in a method other than RFID; and an inspection/alarm part for generating alarms when the number of the gaming currencies whose RF tags are read by the RF reader is not equal to the number of the gaming currencies detected by the plural photosensors.
