Gaming Chip and Card Storage Box with Dual-Frequency RFID Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to prevent fraud and losses of gaming chips, particularly during transportation between the chip tray and the cage in casinos, due to the lack of continuous monitoring and security measures.
Innovation Solution
A system is implemented that uses UHF wireless tags for card IDs and HF wireless tags for chip IDs, with separate readers for each, along with a control unit to detect changes in information, ensuring accurate tracking and monitoring of shuffled playing cards and gaming chips, and a storage box with integrated lock mechanisms to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID tags are used for tracking gaming chips, then monitoring capability is improved, but reading errors increase when multiple tags are read simultaneously
Solution Approach 1:
The system segments the RFID tags into two distinct types operating at different frequencies: HF (high frequency) tags for gaming chips and UHF (ultra-high frequency) tags for playing cards. This segmentation allows each tag type to be read by dedicated readers tuned to their specific frequency, eliminating interference and reading errors that occur when multiple tags of the same type are read simultaneously.
Solution Approach 2:
The patent introduces frequency as an intermediary parameter that mediates between different tag types. By assigning different frequency bands (HF and UHF) to different tag types, the system creates a layered reading structure where HF readers and UHF readers operate independently without interfering with each other, thus resolving the reading error problem while maintaining comprehensive monitoring capability.
2Reliability
If multiple RFID readers are deployed to monitor all gaming chips, then monitoring coverage is improved, but system complexity increases
Solution Approach 1:
The system divides the monitoring function into two separate reader systems: HF readers dedicated to gaming chip tracking and UHF readers dedicated to playing card tracking. This segmentation reduces the complexity of each individual reader system while achieving comprehensive monitoring coverage through the coordinated operation of both systems.
Solution Approach 2:
The dual-frequency RFID system provides multi-functionality by enabling simultaneous tracking of both gaming chips and playing cards through a unified management platform. The system can selectively activate HF or UHF reading based on the specific monitoring need, making the overall system versatile and adaptable to different monitoring scenarios.
3Object-affected harmful factors
If continuous monitoring of gaming chips is implemented, then security against theft is improved, but cost of implementation increases
Solution Approach 1:
The RFID tags on gaming chips and playing cards continuously self-transmit their identification information without requiring active interrogation. The readers passively receive this information, enabling continuous monitoring with minimal energy consumption from the tagging side and reducing overall system cost.
Solution Approach 2:
The patent replaces physical inspection and manual counting mechanisms with automated RFID reading systems. This substitution eliminates the need for human labor in monitoring and counting gaming chips and cards, significantly reducing operational costs while providing continuous, real-time tracking capability.

Implementation Method 1
the card ID and the chip ID are identified using wireless tags
Implementation Method 2
a control unit connected to the card reader and the chip reader and configured to detect a change when information read by the card reader or information read by the chip reader is changed
Data Source
AI summary
A system that managing playing cards to which information is given by an RFID tag and gaming chips to which information is given by an RFID tag. A system is provided with a storage box integrally configured to contain a card drawer for storing playing cards and a chip drawer for storing gaming chips, a card RFID reader for reading information of an RFID tag attached to the playing cards stored in the card drawer, and a chip RFID reader for reading information of the RFID tag attached storing gaming chips stored in the chip drawer. A card RFID reader and a chip RFID reader reads information of each RFID tag using different frequencies.
