E-Ink Transaction Cards for QR-Based Second-Factor Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transaction cards lack robust second-factor authentication mechanisms, particularly in online and physical point-of-sale transactions, leading to increased fraud risks and inefficient resource utilization.
Innovation Solution
Transaction cards equipped with an on-card display capable of generating and displaying a QR code for second-factor authentication, coupled with a mobile device for verification, reducing reliance on network communications and enhancing fraud detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional transaction cards are used without on-card display, then device complexity is reduced, but transaction security and fraud detection capability deteriorate
Solution Approach 1:
The patent merges the display functionality directly into the transaction card by integrating an e-ink display with the card's existing circuitry and power source. This combination allows the card to generate and display QR codes for second-factor authentication, enhancing security without requiring a separate display device. The display is coupled to the transaction and communication circuitry, creating a unified secure transaction system.
2Reliability
If on-card display with QR code generation is added, then second-factor authentication capability is improved, but power consumption increases
Solution Approach 1:
The patent utilizes e-ink display technology which fundamentally changes the power consumption parameters of the display. E-ink displays are electrophoretic and retain images without power, consuming energy only during state changes. This allows the QR code to be displayed and retained without continuous power supply, dramatically reducing the power consumption impact on the card's battery while maintaining authentication security.
3Productivity
If QR code display is implemented on the card, then second-factor authentication speed is improved, but network communication dependency increases
Solution Approach 1:
The patent implements a copying mechanism where the QR code is generated and displayed on the card's e-ink display, then captured by the mobile device's camera. This optical copying method transfers authentication data without requiring complex network communication protocols during the authentication moment. The mobile device subsequently transmits the captured QR code image to the server, simplifying the communication requirements at the point of authentication while maintaining speed.
