NFC Data Format Determination for Simultaneous Mode Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NFC systems do not effectively enable simultaneous operation of reader/writer mode and peer-to-peer mode in information processing apparatuses, limiting data handling and application usage based on data attributes and communication methods.
Innovation Solution
An information processing apparatus with a data format determination unit, data attribute determination unit, and communication method determination unit identifies applicable applications for data read in either peer-to-peer or reader/writer modes, allowing appropriate applications to use the data by determining data formats and communication methods, enabling simultaneous operation of both modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC reader/writer mode is used to read data from NFC devices, then data can be read from the NFC device, but it becomes difficult to determine which application should use the read data when multiple applications are available
Solution Approach 1:
The patent introduces an intermediary mechanism (the determination unit and notification unit) that mediates between the data reading function and multiple applications. This intermediary automatically determines which application should use the read data based on data attributes and communication methods, and notifies the selected application, thereby resolving the complexity of manual application selection while maintaining ease of data reading.
2Adaptability or versatility
If NFC peer-to-peer mode is used for communication, then data can be read and applications can be identified, but it limits the ability to handle data from reader/writer mode
Solution Approach 1:
The patent implements a universal determination unit that can handle data from both peer-to-peer mode and reader/writer mode using the same processing logic. This multi-functional approach allows the system to adapt to different communication modes without increasing overall system complexity, as the determination unit universally applies data attribute analysis and communication method identification across both modes.
3Adaptability or versatility
If data format determination is performed to identify applicable applications, then appropriate applications can use the data, but it increases processing time
Solution Approach 1:
The patent applies preliminary action by pre-establishing data attribute definitions and communication method criteria before data reading occurs. The determination unit uses these pre-defined criteria to quickly match read data with appropriate applications, avoiding time-consuming analysis during the data processing phase and thereby reducing overall processing time while maintaining high application compatibility.

AI summary
An information processing apparatus includes a data format determination unit determining whether data read by near field wireless communications correspond to data read in a peer-to-peer mode; a data attribute determination unit identifying an application that can use the data based on attribute information of the data when it is determined that the data correspond to the data that are read in the peer-to-peer mode; a communication method determination unit identifying an application that can use the data based on a communication method used when the data are read, when it is determined that the data do not correspond to the data that are read in the peer-to-peer mode; and an application use processing unit performing processing so that the application identified by the data attribute determination unit or the application identified by the communication method determination unit can use the data.
