Gaming Chip Inspection Using RFID and Optical Count Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately inspect and count gaming chips stored in a case due to issues with broken or missing radio tags, leading to discrepancies between the actual and calculated number of chips.
Innovation Solution
An inspection system and device that utilize a reading device to read both a radio tag embedded in each gaming chip and optically readable information on the chip's surface, comparing the data to determine any abnormalities or discrepancies in the number or authenticity of the chips.
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 introduces an optical reading device as an intermediary to read optically readable information on gaming chips. This mediator provides an alternative method to verify chip information when radio tags fail, ensuring accurate counting without compromising automation efficiency.
Solution Approach 2:
The system performs preliminary verification by reading optically readable information on gaming chips before finalizing the count. This preliminary action ensures that even if radio tags are broken, the counting accuracy is maintained through alternative verification methods.
2Ease of operation
If only radio tag information is used for inspection, then the inspection process is simple and fast, but reliability deteriorates when radio tags are damaged or absent
Solution Approach 1:
The system performs preliminary verification by reading optically readable information on gaming chips before finalizing the count. This preliminary action ensures that even if radio tags are broken, the counting accuracy is maintained through alternative verification methods.
Solution Approach 2:
The patent introduces an optical reading device as an intermediary to read optically readable information on gaming chips. This mediator provides an alternative method to verify chip information when radio tags fail, ensuring accurate counting without compromising automation efficiency.
3Reliability
If the inspection system uses multiple verification methods, then reliability improves, but device complexity increases
Solution Approach 1:
The inspection system is designed with multi-functionality, where a single system can perform both radio tag reading and optical information reading. This universal approach allows the system to handle multiple verification methods without proportionally increasing complexity, as the same hardware platform supports both inspection modes.

Function Achieved in This Case
Ensures reliable inspection and counting of gaming chips by verifying the consistency of information from both the radio tag and surface markings, detecting any unauthorized or damaged chips within the case.
Implementation Method 1
a radio tag storing gaming chip information being embedded in each of the gaming chips
Implementation Method 2
physical information of the gaming chip obtained from a physical measurement means other than the reading device
Data Source
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.
