Gaming Chip Inspection Using RFID and Optical Cross-Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately inspect gaming chips contained in a case for authenticity and damage when the radio tag is broken or missing, leading to discrepancies between the actual and calculated number of chips.
Innovation Solution
An inspection system and device that utilize a reading device to acquire gaming chip information from both a radio tag and an optically readable surface, comparing these with a maximum storable count and physical characteristics, and a determining unit to detect abnormalities, including a database for radio tag information to verify authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of gaming chips is calculated based on radio tag information, then the counting process is automated and efficient, but the accuracy deteriorates when radio tags are broken or missing
Solution Approach 1:
The patent combines multiple information sources (radio tag data, optical surface reading, and physical case characteristics) into a unified inspection system. The determining unit integrates these diverse data streams to cross-validate the number of gaming chips, ensuring accurate counting even when radio tags are broken or missing by relying on alternative verification methods.
2Device complexity
If only radio tag information is used for inspection, then the inspection process is simple and fast, but the reliability deteriorates when radio tags are broken or missing
Solution Approach 1:
The patent implements preliminary verification by reading multiple types of information (radio tag, optical surface characteristics) before making a final determination. The system prepares multiple data sources in advance so that if the radio tag information is found to be unreliable or missing, alternative verification methods are already available to ensure accurate inspection results.
3Productivity
If the case capacity is not verified, then the inspection process is faster, but the accuracy of chip count deteriorates
Solution Approach 1:
The patent incorporates feedback mechanisms where the determining unit continuously compares the number of gaming chips derived from radio tag information against the known case capacity and physical characteristics. When discrepancies are detected, the system adjusts its verification process by incorporating additional checks such as optical surface reading to ensure accurate chip count while maintaining efficient inspection throughput.

AI summary
An inspection system inspects gaming chips each having a color or a display indicating a value on an outer surface in a state where the gaming chips are stored in a case in which a maximum of the number of gaming chips to be stored is limited, and a radio tag storing gaming chip information is embedded in each of the gaming chips. The gaming chips are stored in the case capable of containing a row of gaming chips stacked in a thickness direction, and the inspection system includes a reading device that reads the radio tag of the gaming chip in the case and acquires gaming chip information of the gaming chip and a determining unit that compares the gaming chip information with a maximum of the number of gaming chips storable in the case and determines an abnormality of the gaming chip in the case when the number of gaming chips obtained from the gaming chip information is different from a maximum of the number of storable gaming chips.
