Multi-UID RFID Encoding for Disparate System Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID systems face challenges in integrating disparate systems due to the inability to modify or reprogram Unique Identifiers (UIDs), leading to costly and time-consuming updates when new systems are added, as each system must accommodate the unique identifier schemes of others.
Innovation Solution
Implementing multi-UID RFID encoding with identifier mapping and translation, allowing each system to store its unique identifier without knowledge of other systems' requirements, using Near Field Communication (NFC) and NFC Data Exchange Format (NDEF) for communication, and incorporating computing modules like NFC Reader, NFC Reader Manager, Tag Message, and Tag Update Process to facilitate communication across systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed UID RFID device is used, then the device maintains reliability and stability, but the system integration complexity increases when adding new systems
Solution Approach 1:
The patent segments the identification function by storing multiple UIDs (first UID and second UID) separately in the RFID device memory. Each UID can be independently assigned to different systems, allowing System 1 to use the first UID and System 2 to use the second UID without interfering with each other. This segmentation resolves the integration complexity while maintaining UID stability within each system context.
Solution Approach 2:
The RFID device is designed with multi-functionality to store and present different UIDs to different systems. The device can function as if it were multiple different RFID tags, each with its own UID, depending on which system is querying it. This universality allows a single fixed UID device to serve multiple systems without requiring modification to the device hardware, thus maintaining reliability while reducing integration complexity.
2Adaptability or versatility
If each system stores its unique identifier in the RFID device, then system adaptability improves, but the device complexity increases
Solution Approach 1:
The patent divides the RFID device memory into separate segments or blocks, where each system's unique identifier is stored in a designated memory block. For example, System 1's identifier is stored in one memory block while System 2's identifier is stored in another. This segmentation allows multiple systems to coexist in the same device without complex interactions, achieving high adaptability while keeping the device structure relatively simple and organized.

AI summary
A device, system, and method for integration of disparate systems uses multi-UID RFID encoding whereby all systems have a place to store their unique identifier without having to have knowledge of the other systems' requirements while at the same time allowing each system to communicate with the other systems by utilizing the other systems' unique identifier. Modules comprise an NFC Reader 405; an NFC Reader Manager 410; an NFC Reader Read Thread 415; a Tag module 420; a Tag Message 425; and a Tag Update Process 430.
