Fingerprint Payment Launch for Faster Mobile Terminal Checkout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals face inconvenience in making offline payments due to the complexity of switching to a home screen and returning to a currently running content after payment, especially when using fingerprint sensors for authentication.
Innovation Solution
A mobile terminal equipped with a fingerprint sensing unit that allows for launching a payment application directly from a locked state, enabling quick payment through fingerprint input and FIDO authentication, and returning to the previous content with a back key input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile terminal switches to home screen to launch payment application, then the payment can be made, but the operation becomes complicated and time-consuming
Solution Approach 1:
The system pre-loads and stores the payment application in a readily accessible state during lock mode, so that when a fingerprint is detected, the payment application can be immediately launched without requiring the user to navigate through the home screen or recently used applications list. This preliminary preparation eliminates the time-consuming screen switching operation.
2Ease of operation
If the mobile terminal returns to recently used application list after payment, then the previous content can be accessed, but the procedure becomes complicated
Solution Approach 1:
The system extracts the previously viewed content information and stores it in a dedicated recent content list. After payment completion, the system directly retrieves and displays this extracted content information, bypassing the complex recently used application list navigation. This extraction approach simplifies the return procedure by directly accessing the needed content without intermediate steps.
3Reliability
If the fingerprint sensor is used for payment authentication, then the payment security is improved, but the operation becomes more complex due to multiple authentication steps
Solution Approach 1:
The system merges the fingerprint authentication function with the payment launch function into a single integrated operation. When a fingerprint is detected during lock mode, the system simultaneously performs authentication verification and directly launches the payment application in one step, rather than requiring separate authentication and application launching steps. This merging maintains security while simplifying the user operation.
