NFC Tag Interrupt Configuration for Data Transfer Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing near-field wireless communication systems lack a mechanism to configure interrupt settings based on the direction of data transfer, requiring manual selection of interrupt signals by the user for data writing and reading operations in near-field wireless communication tags.
Innovation Solution
An information processing apparatus with a selection unit to choose between data writing and reading functions and a setting unit to configure corresponding interrupt settings for near-field wireless communication tags, generating interrupt signals based on user instructions for data transfer directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual selection of interrupt signals is required for data writing and reading operations, then the system provides flexibility in interrupt configuration, but the ease of operation deteriorates due to complex user configuration requirements
Solution Approach 1:
The near-field wireless communication tag automatically determines the data transfer direction (reading or writing) and selects the appropriate interrupt signal type without requiring manual user configuration. The tag serves itself by monitoring communication requests and autonomously configuring its interrupt settings based on whether it is reading data from or writing data to an external apparatus, thereby eliminating complex user configuration requirements while maintaining interrupt configuration flexibility
Solution Approach 2:
The interrupt signal type is made dynamic and adjustable based on the actual data transfer direction. The tag can switch between different interrupt signal types (first interrupt signal for writing operations, second interrupt signal for reading operations) depending on the communication mode, allowing the system to adapt its behavior dynamically rather than requiring static manual configuration
2Ease of operation
If the tag autonomously performs wireless communication with automatic interrupt configuration, then the ease of operation improves, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The interrupt configuration function is merged with the existing wireless communication processing logic within the tag. The tag's control unit already handles communication protocols and data transfer; by integrating the interrupt signal selection into this existing control structure, the system achieves automatic configuration without adding significant complexity. The same control unit that manages data reading and writing also determines the appropriate interrupt signal type
Solution Approach 2:
The tag pre-configures its interrupt signal settings in advance based on the detected data transfer direction before actual data operations commence. By determining the communication mode (reading or writing) and setting the appropriate interrupt signal type beforehand, the system avoids the need for complex real-time configuration mechanisms during active communication

AI summary
An information processing apparatus capable of configuring interrupt settings of a NFC tag by taking into account the direction of data transfer. An information processing apparatus includes an NFC tag. A user selects either a first function in which a mobile terminal writes data into the NFC tag or a second function in which the terminal reads data held by the NFC tag. The NFC tag is set to one of a first interrupt setting for generating an interrupt signal when data is written into the NFC tag by the terminal, and a second interrupt setting for generating an interrupt signal when data held by the NFC tag is read by the terminal. When the first function is selected, the NFC tag is set to the first interrupt setting, and when the second function is selected, the NFC tag is set to the second interrupt setting.
