NFC Antenna Selection via Proximity Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication apparatuses with multiple antennas for near field communication can unintentionally perform unwanted processes, such as unintended product purchases, due to near field communication being initiated through an antenna other than the user's intended choice.
Innovation Solution
A control device that includes a continuation determination unit to assess the proximity of an information communication terminal to multiple antennas and a communication antenna determination unit to identify the intended antenna for near field communication, preventing unwanted processes by ensuring the correct antenna is used for the intended process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication apparatus includes a plurality of antennas for performing near field communication, then various services can be transmitted via respective antennas, but unwanted processes may be performed due to near field communication being initiated through an antenna other than the user's intended choice
Solution Approach 1:
The control device determines whether the contact or proximity state continues before executing the near field communication process. This preliminary check ensures that the communication is initiated only when the terminal remains in contact with or proximity to the intended antenna, preventing unwanted processes from occurring through accidental antenna selection.
2Speed
If near field communication is performed via any antenna that detects a terminal, then communication speed is improved, but the process may not match user intention leading to unwanted transactions
Solution Approach 1:
The control device continuously monitors whether the contact or proximity state continues and uses this feedback to determine if the near field communication process should be executed. This feedback mechanism ensures that the communication reflects the user's intended antenna selection while maintaining rapid response when the condition is met.

AI summary
An unwanted process is prevented from being performed due to near field communication based on a process performed via an antenna which is not intended by a user. An information processing apparatus (1) includes a communication antenna determination unit (22) configured to, when a proximity state of an NFC terminal (10) to an NFC antenna (12) continues, determines that the NFC antenna (12) is an NFC antenna (12) that performs near field communication for executing a prescribed process.
