NFC Terminal Header Extraction for Application Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NFC systems face compatibility issues with near field communication tag information, leading to potential failure in recognizing and executing applications due to lack of NFC header information, resulting in incomplete operations.
Innovation Solution
Incorporating an NFC reading unit and NFC tag information processor in NFC terminals to extract and analyze NFC header information, with a communication unit to request and retrieve suitable applications from an NFC management server, ensuring correct application installation and execution based on the tag information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an application is executed before tag information is read, then the application can be prepared in advance, but the terminal may access applications that are not compatible with the tag information
Solution Approach 1:
The patent extracts and analyzes NFC header information from tag information in advance, before application execution. This preliminary analysis enables the system to identify compatible applications beforehand, resolving the contradiction by preparing application selection criteria in advance while ensuring compatibility through pre-analysis of tag information characteristics.
Solution Approach 2:
The patent introduces NFC header information as an intermediary element between tag information and application selection. This intermediary contains essential compatibility criteria that mediate between the raw tag data and the application execution decision, enabling reliable compatibility assessment without executing incompatible applications.
2Reliability
If tag information is read and analyzed to filter applications, then application compatibility is improved, but the operation time increases due to multiple filtering steps
Solution Approach 1:
The patent extracts only the essential NFC header information from the complete tag information, separating the critical compatibility-determining elements from the rest of the tag data. This extraction approach maintains high compatibility assessment accuracy while significantly reducing the amount of data that needs to be processed, thereby decreasing operation time.
Solution Approach 2:
The patent performs partial analysis by focusing only on the NFC header portion of tag information rather than analyzing the entire tag data structure. This partial action approach provides sufficient information for compatibility determination without the time cost of complete tag information analysis.
3Ease of operation
If basic application is set by terminal user, then user preference is respected, but the basic application may not recognize the tag information
Solution Approach 1:
The patent implements a feedback mechanism where the system analyzes NFC header information from tag information and provides compatibility assessment results. This feedback loop allows the system to inform users whether their selected basic application is compatible with the scanned tag, enabling users to make informed decisions or select alternative applications from a filtered list of compatible options.
