Gaming Chip Inspection Using RFID and Optical Side Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems are unable to inspect multiple gaming chips contained within a case for authenticity and integrity, including detection of unauthorized or counterfeit chips.
Innovation Solution
An inspection system and device that utilize both a first reading device to acquire gaming chip information from a radio tag and a second reading device to optically read information from the side surface, enabling comprehensive inspection of gaming chips within a case, including determining authenticity, damage, and number verification through multiple information sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a system uses only radio tag reading to inspect gaming chips, then the inspection process is simple and fast, but it cannot detect counterfeit chips that have fake radio tags
Solution Approach 1:
The patent combines radio tag reading (first reading device) with optical code recognition (second reading device) into a unified inspection system. The determining unit integrates information from both reading methods to comprehensively verify gaming chip authenticity, preventing counterfeit detection gaps while maintaining efficient batch inspection capability
2Measurement precision
If a system uses only optical code reading to inspect gaming chips, then it can verify chip information visually, but it cannot read information from chips with obscured or damaged surface codes
Solution Approach 1:
The patent introduces a determining unit as an intermediary that coordinates between the radio tag reader and optical code reader. This mediator intelligently selects and combines information sources, using radio tag data when optical codes are damaged or obscured, thereby ensuring continuous accurate verification without requiring complex manual intervention
3Reliability
If the system inspects gaming chips after they are removed from the case, then individual chip inspection is thorough, but it cannot detect chips that were stolen or replaced during transport and storage
Solution Approach 1:
The patent enables inspection of gaming chips while they are still contained in sealed cases, performing verification before the chips are distributed to cashiers or game tables. This preliminary inspection prevents stolen or counterfeit chips from entering circulation, addressing security gaps in the transport and storage chain without requiring time-consuming post-removal verification
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system reliably inspects gaming chips within a case by comparing information from both reading devices, ensuring accurate detection of counterfeit or missing chips, and verifying the integrity of the chip stack.
Implementation Method 1
a first reading device that acquires the first gaming chip information of the gaming chip contained in the case
Implementation Method 2
a second reading device that optically reads the side surface of the gaming chip contained in the case and acquires the second gaming chip information
