Mobile Device Screen Interface for Secure Payment Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device payment systems face challenges in securely authorizing transactions without local mechanical input, particularly in scenarios where a user is near a point-of-sale terminal but has not initiated a payment locally, leading to delayed or failed transactions.
Innovation Solution
A mobile device apparatus that securely stores payment information, detects proximity to a point-of-sale terminal, presents a stimulus for missing mechanical input, and upon receiving the input, enables the retrieval and transmission of payment information for authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system automatically transmits payment information when detecting proximity to POS terminal, then transaction speed is improved, but security is worsened due to lack of user authorization
Solution Approach 1:
The system performs preliminary actions by detecting proximity to the POS terminal and preparing payment information in advance, but delays actual transmission until user authorization is received. This allows the system to be ready for quick transaction while maintaining security through required user input.
Solution Approach 2:
The system implements feedback by monitoring for mechanical input from the user and using this input to trigger or prevent payment information transmission. The transaction process is controlled by continuous feedback from the user's physical actions, ensuring security while enabling efficient processing when authorized.
2Reliability
If the system requires mechanical input for payment authorization, then security is improved, but transaction time is worsened due to waiting for user input
Solution Approach 1:
The system performs preliminary detection of the POS terminal and preparation of payment information before user authorization is needed. This preliminary action reduces the actual transaction time after user input is received, maintaining security while minimizing delay.
Solution Approach 2:
The system dynamically adjusts its response based on the timing and nature of user input. It can process authorized transactions immediately when mechanical input is detected, while providing appropriate feedback when no input is received within the expected time window, optimizing the balance between security and speed.
3Ease of operation
If the system presents multiple stimuli for missing input, then user awareness is improved, but interface complexity is worsened
Solution Approach 1:
The feedback system is segmented into distinct stages: initial proximity detection, intermediate reminders when input is missing, and final timeout handling. Each stage presents appropriate stimuli tailored to the current state, improving user awareness without requiring a complex overall interface structure.
Solution Approach 2:
The system employs periodic feedback actions at appropriate intervals when mechanical input is not received. These periodic reminders serve to alert users of missing authorization without creating a continuously complex interface, maintaining simplicity while ensuring user awareness.
