Wearable Payment Code Display With Server-Side Request Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing settlement systems that utilize wearable devices for code display rely heavily on portable terminals for processing, leading to increased load and potential errors, which compromises user convenience.
Innovation Solution
A settlement system where the wearable device primarily transmits code display requests to a settlement server, reducing the processing load on the portable terminal and minimizing display failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the portable terminal executes the series of processes including requesting code issuance from the server, then the settlement service can be provided through the wearable device, but the processing load of the portable terminal increases and errors may occur
Solution Approach 1:
The patent extracts the code issuance request function from the portable terminal and assigns it to the wearable device. The wearable device directly communicates with the server to request and receive codes, while the portable terminal only handles authentication token issuance. This separation removes the problematic processing load from the portable terminal while maintaining user convenience through the wearable device's display capability.
Solution Approach 2:
The patent introduces an authentication token as an intermediary mechanism. The portable terminal issues authentication tokens to the wearable device, which then uses these tokens to independently communicate with the server for code issuance. This intermediary approach allows the portable terminal to maintain security control while delegating the code request process to the wearable device, preventing processing load issues.
2Device complexity
If the portable terminal handles all settlement processes, then comprehensive control is maintained, but processing load increases leading to potential errors
Solution Approach 1:
The patent segments the settlement system into distinct functional modules: the portable terminal handles authentication token issuance, the wearable device handles code issuance requests and display, and the server handles code generation and validation. This segmentation distributes processing load across multiple devices, improving overall processing efficiency while maintaining simple system control through clear division of responsibilities.

AI summary
A settlement system includes at least one processor that receives, from a wearable device connectable to a portable terminal of a user in a settlement service, a code display request related to display of a code used in the settlement service, and transmits code display information related to display of the code to the wearable device when the code display request is received.
