NFC Connection for Portable Data Carrier Websites Without QR Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with visual impairments face challenges in connecting their mobile devices to the website of a portable data carrier, such as a bank card, due to the need to focus a camera on a QR code, which they may not be able to see.
Innovation Solution
A method utilizing contactless communication between a portable data carrier and a mobile device, enabling automatic connection by placing the data carrier next to the device, with separate encrypted and non-encrypted data storage areas for secure and accessible data transfer, using Near Field Communication (NFC) standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a QR code is used on the portable data carrier to enable connection with the website, then the connection functionality is improved, but the accessibility for visually impaired users deteriorates as they cannot see or focus on the QR code
Solution Approach 1:
The patent replaces the optical-mechanical QR code scanning system with a contactless electromagnetic communication system. Instead of requiring visual focus and camera alignment, the mobile device uses contactless communication (e.g., NFC) to automatically read data from the portable data carrier when placed nearby, eliminating the need for visual interaction with any code or symbol.
Solution Approach 2:
The patent introduces contactless communication as an intermediary mechanism between the mobile device and the portable data carrier. This intermediary enables automatic data transfer without requiring direct visual contact or manual intervention, allowing visually impaired users to connect simply by placing the carrier near their mobile device.
2Ease of operation
If contactless communication is used between the portable data carrier and mobile device, then the ease of operation is improved for visually impaired users, but the device complexity increases due to additional communication interfaces
Solution Approach 1:
The patent leverages universal contactless communication standards (such as NFC) that are already integrated into many mobile devices for various functions like contactless payments. By using these existing multi-functional interfaces, the system enables new connection capabilities without requiring entirely new hardware, thus limiting the increase in device complexity.
