Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reading RFID tokens lack the ability to communicate with RFID tokens using electronic devices without an integrated RFID interface, limiting their functionality in applications like authentication and data access.
Innovation Solution
A method that converts RFID read commands into memory card commands, allowing an RFID card with a memory card interface to communicate with an RFID token through a memory card reader, enabling communication between an electronic device without an RFID interface and an RFID token using a driver program that integrates with the device's operating system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electronic device without an RFID interface is used, then the device cannot communicate with RFID tokens directly, but adding an RFID reader increases device complexity and cost
Solution Approach 1:
The patent introduces an RFID card as an intermediary device that contains both an RFID interface and a memory card interface. The RFID card acts as a mediator between the electronic device without RFID capability and the RFID token, enabling communication through the existing memory card interface without modifying the electronic device's hardware architecture.
Solution Approach 2:
The RFID card is designed with dual functionality: it can communicate with RFID tokens via RFID interface and simultaneously interface with electronic devices through standard memory card interfaces. This multi-functionality allows a single device to serve both purposes, eliminating the need for separate RFID readers in electronic devices.
2Adaptability or versatility
If an RFID card with memory card interface is introduced, then existing electronic devices can access RFID tokens, but the conversion between RFID commands and memory card commands increases processing complexity
Solution Approach 1:
The driver program serves as a software intermediary that translates between RFID communication protocols and memory card interface protocols. This translation layer handles the complexity of command conversion, allowing the application layer to interact with RFID tokens through familiar memory card interface commands without dealing with protocol differences.
Solution Approach 2:
The system creates a virtual representation of RFID communication through the memory card interface. By copying the essential functionality of RFID commands into memory card command structures, the system allows standard memory card interfaces to access RFID tokens without requiring native RFID support in the electronic device.
3Ease of manufacture
If command conversion is implemented through driver program, then RFID access is enabled without hardware modification, but the conversion process increases processing time
Solution Approach 1:
The driver program is pre-configured with translation rules and protocols for converting RFID commands to memory card commands. This preliminary setup allows the conversion process to follow established patterns rather than requiring complex real-time analysis, reducing processing overhead while maintaining flexibility.
