NFC Information Management in Image Forming Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices, such as image forming apparatuses, face limitations in storing and rewriting Near Field Communication (NFC) information due to the small storage capacity of NFC devices, which restricts the amount of data that can be stored and managed for external apparatuses like smartphones and personal computers.
Innovation Solution
The implementation of an information processing device with multiple NFC devices that support NFC standards, allowing for data storage and rewriting based on the device's state transitions, enabling efficient communication and management of NFC information through active and passive tag functionalities, and facilitating high-speed communication protocols like WiFi and Bluetooth.

1Quantity of substance
If NFC information is stored in the proximity communication device, then communication with external apparatuses is enabled, but the storage capacity is limited and cannot accommodate large amounts of data
Solution Approach 1:
The patent divides NFC information into multiple types (first type and second type) and stores them in different storage areas within the proximity communication device. First type information related to authentication is stored in a first storage area, while second type information related to service provision is stored in a second storage area. This segmentation allows efficient management of limited storage capacity while maintaining adaptability for different communication scenarios.
Solution Approach 2:
The patent implements dynamic rewriting of NFC information based on apparatus state transitions. When the image forming apparatus transitions between different states (e.g., from a state where a user account is registered to a state where the account is deleted), the NFC information is automatically updated to reflect the current state. This dynamic approach maximizes the utility of stored information within the constrained storage capacity.
2Reliability
If NFC information is rewritten based on apparatus state transitions, then communication accuracy is improved, but additional control mechanisms are required
Solution Approach 1:
The patent establishes a feedback mechanism where the proximity communication device monitors apparatus state transitions and automatically rewrites NFC information accordingly. The system detects changes in apparatus state (such as user account registration or deletion) and triggers appropriate NFC information updates. This feedback-based approach improves communication accuracy by ensuring NFC information always reflects the current apparatus state, while the automation reduces the perceived complexity for users.

AI summary
An information processing device has at least one proximity communication device. The information processing device is an apparatus in which information in a storage area in the at least one proximity communication device is capable of being provided for an external apparatus. The information in the storage area is rewritten in accordance with transition of an apparatus state of the information processing device.
