Smart Broadcast Device Payment Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In offline electronic transactions, there is a need for a more timely and reliable solution to provide transaction result feedback, as existing methods lack efficiency in communicating payment results to users and merchants.
Innovation Solution
A smart broadcast device that integrates a payment graphic code and a payment result broadcast function, allowing users to make payments by scanning the code and receiving a payment result audio signal through a communication module, enabling timely and reliable payment result broadcasting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If payment result feedback is provided through existing methods, then the transaction process is completed, but the feedback is not timely and reliable enough
Solution Approach 1:
The patent implements a feedback mechanism where the broadcast device receives transaction result information from the payment system and automatically broadcasts it through audio output. This closed-loop feedback system ensures that users and merchants receive timely and reliable payment result notifications, directly addressing the contradiction between feedback reliability and time delay.
2Reliability
If a smart broadcast device integrates payment graphic code and broadcast function, then payment result feedback becomes timely and reliable, but the device complexity increases
Solution Approach 1:
The broadcast device is designed to perform multiple functions: displaying payment graphic codes for scanning and broadcasting transaction results through audio output. By making the device universal and multi-functional, the patent reduces the need for separate dedicated devices, thereby managing complexity while improving reliability.
Solution Approach 2:
The patent introduces a communication module as an intermediary between the payment system and the broadcast device. This module handles the complex tasks of receiving and processing transaction result information, allowing the broadcast device to maintain relative simplicity while still achieving reliable and timely feedback through its integrated functions.
3Reliability
If payment information is transmitted through scanning and decryption, then security is enhanced, but the operation process becomes more complex
Solution Approach 1:
The patent implements a self-service mechanism where the broadcast device automatically receives, processes, and broadcasts transaction result information without requiring manual intervention from users or merchants. This automation maintains high security through encrypted communication while simplifying the operation process, as users only need to scan the code and automatically receive feedback.
