Merchandise Security Kit with Swappable RFID Tacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of combination hard tags with both electronic article surveillance (EAS) and radio frequency identification (RFID) capabilities into the retail landscape is hindered due to the high cost of RFID devices, which many participants in the retail supply chain are not equipped to read or program, making them unwilling to adopt this more expensive solution.
Innovation Solution
A security kit that allows users to easily modify hard tags to include RFID capabilities by swapping standard tacks with RFID-enabled tacks, which are equipped with an integrated circuit chip, enabling both EAS and RFID functions without the need for extensive RFID reader infrastructure, thus reducing costs and enhancing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If combination hard tags with both EAS and RFID capabilities are integrated into the retail landscape, then product identification and tracking capabilities are improved, but device cost and system complexity increase
Solution Approach 1:
The patent divides the RFID system into two separate components: a simple RFID reader device and RFID-enabled stickers. This segmentation allows the RFID functionality to be added without requiring complex integrated systems, reducing overall system complexity while maintaining versatility.
Solution Approach 2:
The RFID reader device is designed to work with multiple types of RFID stickers and can be used across different retail applications. The reader can identify and track various products using universal RFID technology, improving adaptability without requiring separate specialized systems for each application.
2Adaptability or versatility
If combination hard tags with both EAS and RFID capabilities are integrated into the retail landscape, then product identification and tracking capabilities are improved, but device cost increases
Solution Approach 1:
The patent employs disposable RFID stickers that are inexpensive to manufacture and apply to products. These stickers serve their identification purpose and can be discarded after use, eliminating the need for expensive reusable RFID tags while maintaining product identification capabilities.
Solution Approach 2:
The RFID functionality is extracted from expensive integrated hard tags and placed into separate, cheaper stickers. This extraction allows the RFID capability to be added to existing EAS systems without requiring replacement of the entire tag system, reducing overall device cost.
3Adaptability or versatility
If RFID components are integrated into hard tags, then product identification capabilities are improved, but shipping and programming costs increase
Solution Approach 1:
RFID stickers are pre-programmed with product identification information before being applied to products. This preliminary action eliminates the need for on-site programming at retail locations, reducing programming costs and time requirements while maintaining product identification capabilities.

AI summary
A merchandise security kit includes a tag body, a first tack adapted to be removably attached to the tag body to form a first reusable hard tag that is limited to electronic article surveillance (EAS) capabilities, and a second tack adapted to be removably attached to the tag body to form a second reusable hard tag that is provided with both EAS and radio frequency identification (RFID) capabilities. The tag body comprises a security inlay that is disposed within a protective casing, the security inlay including an antenna and an EAS marker. The second tack comprises an enlarged head, a sharpened pin connected to the head and an integrated circuit (IC) chip embedded within the head. With the second tack attached to the tag body, the IC chip either conductively or reactively couples to the antenna in the tag body to provide the second hard tag with its RFID capabilities.
