Biometric Sensor Under Touchscreen for Simplified Payment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic payment systems on devices require multiple steps and can be cumbersome for users unfamiliar with the process, involving password entry and complex procedures.
Innovation Solution
An electronic device with a touchscreen and biometric sensor that allows users to designate a product for payment by touching an object on the screen, using biometric information to authenticate and complete the payment process in a simplified manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional payment procedures are used with password entry and multiple steps, then payment security is maintained, but user convenience and operation simplicity deteriorate
Solution Approach 1:
The patent merges the biometric authentication function with the touchscreen display by placing the biometric sensor underneath the display. This integration allows the authentication and display functions to occur in the same spatial location, eliminating the need for separate authentication steps and reducing overall system complexity while improving ease of operation.
Solution Approach 2:
The touchscreen display serves multiple functions: it displays information to the user and simultaneously houses the biometric sensor for authentication. This multi-functionality reduces the number of separate components needed and simplifies the payment procedure while maintaining security.
2Speed
If biometric sensor is integrated into touchscreen, then payment speed and convenience are improved, but device structural complexity increases
Solution Approach 1:
The biometric sensor is nested within the touchscreen structure, specifically positioned underneath the display. This nesting approach allows the sensor to be integrated into the existing device architecture without requiring separate mounting spaces or complex external assemblies, thereby improving payment speed while minimizing structural complexity increases.
3Productivity
If multiple payment steps are required including password entry, then payment security is ensured, but user time and operational efficiency are reduced
Solution Approach 1:
The biometric authentication is performed simultaneously with the touch input on the touchscreen, rather than as a separate subsequent step. This preliminary action approach allows the system to authenticate the user during the natural interaction of selecting a payment option, eliminating additional time-consuming steps and improving overall payment processing efficiency.
