User Medium Identification via Optical Code and RFID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identification systems require physical presence of user media at a central location for initialization, which is inconvenient for decentralized systems and may not be feasible in all organizational setups, and existing alternatives like RFID programming are not universally supported.
Innovation Solution
An identification system that uses user media with integrated circuits and optically readable codes, allowing for authorization updates without physical modification, using a user management device to communicate with reading devices via radio waves or other means, enabling authorization without physical presence through optically readable data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If user media are initialized at a central location using RFID programming, then authorization can be managed centrally, but physical presence is required and system complexity increases
Solution Approach 1:
The patent uses optical copies (barcodes or QR codes) of the identification code as a substitute for the physical RFID tag itself. Instead of requiring physical presence for RFID programming, the system creates an optical replica that can be scanned and processed remotely, eliminating the need for physical contact while maintaining the authorization management function
Solution Approach 2:
The patent replaces the mechanical/physical RFID programming process with an optical scanning and image processing system. The physical act of programming via RFID contact is substituted by optical detection of barcodes/QR codes followed by digital image processing and data extraction, eliminating the need for physical presence at a centralized RFID programming location
2Ease of operation
If RFID tags are programmed for decentralized user media, then physical presence at central unit is avoided, but not all standards support this function
Solution Approach 1:
The patent makes the user media universally compatible by adding multiple identification systems: both RFID tags and optical codes (barcodes/QR codes). This multi-functional approach ensures that the user media can be processed by various systems - optical scanners for decentralized initialization and RFID readers for authentication - making the solution adaptable to different standards and platforms
3Productivity
If user media contain only RFID tags, then contactless data exchange is enabled, but optical verification and remote registration are not possible
Solution Approach 1:
The patent merges two different data carrier technologies - RFID tags and optical codes (barcodes/QR codes) - into a single user medium. This combination allows the system to leverage the contactless data exchange capability of RFID while simultaneously enabling optical verification and remote registration through the barcode/QR code, achieving both functions in one integrated solution
