RFID-GPS Asset Tracking System for Facility Boundary Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID tracking systems primarily focus on inventory management within facilities and do not address security concerns such as unauthorized movement of items outside the facility or provide tracking beyond the facility boundaries.
Innovation Solution
A security system integrating RFID tags and GPS monitoring, where RFID tags are used to track items within a facility and transition to GPS tracking when items exit, ensuring continuous monitoring and authorization verification at entry and exit points, with additional features like stealth tags for area deactivation and inventory control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID tags are used to track items within a facility, then inventory management capability is improved, but security tracking capability outside the facility deteriorates
Solution Approach 1:
The tracking system is designed to perform multiple functions: RFID tracking within facility boundaries and GPS tracking outside facility boundaries. The system automatically transitions between tracking methods based on location, enabling both inventory management and security tracking capabilities to coexist in a single universal system.
2Measurement precision
If RFID tracking is used for inventory management within facilities, then tracking accuracy at specific locations is improved, but tracking coverage beyond facility boundaries deteriorates
Solution Approach 1:
The tracking system is segmented into two distinct operational modes: RFID-based tracking for indoor facility locations and GPS-based tracking for outdoor locations. The system divides the tracking space into facility-boundary segments, using appropriate tracking technology for each segment to maintain both accuracy and coverage.
Solution Approach 2:
The system transitions from two-dimensional RFID tracking (within facility boundaries) to three-dimensional GPS tracking (global coverage). By adding the GPS dimension, the system expands tracking coverage beyond facility walls while maintaining the precision of RFID tracking within the facility through automatic mode switching.
3Device complexity
If a unified tracking system is implemented for both inventory and security, then system simplicity is improved, but functionality for both inventory management and security tracking deteriorates
Solution Approach 1:
The system employs a universal tracking platform that automatically selects between RFID and GPS technologies based on location. This multi-functional design allows a single system to provide both inventory management (through RFID) and security tracking (through GPS) capabilities without requiring separate specialized systems.

AI summary
Systems and methods are disclosed for tracking an item using a RFID surveillance system. In some embodiments, a security controller is connected to a point of sale system with at least one RFID tag reader. In these embodiments, the RFID tag reader is associated with an area that is observable through a video camera. If the tag reader does not recognize information obtained from a RFID tag, the tag reader may activate the video camera. When the video camera is activated, the video camera may capture images and send them to a recording device.
