Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing near field communication technologies require complex operations for users to obtain device information, leading to a poor user experience due to the need for organizing multiple commands and handling various device-specific formats.
Innovation Solution
A method and system that simplify the process by sending commands to select and read near field communication data exchange format applications and files, determining their existence, and writing device information into a format file for easy retrieval by the terminal, thereby streamlining the information acquisition process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple private commands are organized according to different near field communication devices to obtain device information, then the information can be retrieved, but the operation becomes complicated and user experience deteriorates
Solution Approach 1:
The patent implements a universal command structure that can retrieve information from different NFC devices without requiring device-specific command variations. The terminal sends standardized read commands that work across multiple device types, eliminating the need to organize separate private commands for each device while maintaining reliable information retrieval through a unified interface
2Ease of operation
If standardized command sequences are used to simplify the information acquisition process, then ease of operation improves, but the ability to handle device-specific formats may be compromised
Solution Approach 1:
The patent introduces an intermediary layer in the form of a standardized command interface that mediates between the terminal and diverse NFC devices. This intermediary standardized protocol translates universal commands into device-specific operations internally, allowing simplified user interaction while maintaining compatibility with various device formats through the mediating command structure
3Device complexity
If a unified data exchange format is implemented across all near field communication devices, then operation complexity is reduced, but the adaptability to different device types decreases
Solution Approach 1:
The patent implements a universal data exchange format that serves multiple device types through a single standardized structure. The unified format includes flexible fields that can accommodate different device-specific information while maintaining a consistent overall structure, allowing one format to handle diverse NFC devices without requiring device-type-specific command variations

AI summary
A communication field, more particularly to a method for providing near field communication device information for a user and a system therefor, where the method includes: when a near field communication device receives a command for reading a near field communication data exchange format file, writing the near field communication device information and a preset application identifier into the near field communication data exchange format file and sending the near field communication data exchange format file to a terminal; obtaining, by the terminal, an application identifier and the near field communication device information from the near field communication data exchange format file; initiating an application corresponding to the application identifier and storing the near field communication device information to a position readable by the application. The method provides a great convenience for a user to obtain the near field communication device information.
