Audio-Based Payment Encoding for Cashless Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing payment methods, such as cash and bank cards, face inconveniences in scenarios like public transportation where exact change is needed or POS machines are required, and may not be implemented in all settings, leading to inefficiencies and increased costs.
Innovation Solution
A method and system using audio encoding and broadcasting between clients to facilitate payment transactions, where a payee encodes payment information and broadcasts it to a payer, who decodes and initiates a payment request to a server for funds transfer, enabling convenient, quick, and reliable payments without the need for physical presence or additional infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cash payment is used, then exact amount including small changes is necessary, but this causes inconveniences to the user
Solution Approach 1:
The patent replaces the mechanical system of physical cash handling with an electronic audio-based payment system. The payee's device converts payment information into audio signals that are transmitted to the payer's device, eliminating the need for physical cash and exact change preparation.
Solution Approach 2:
The patent introduces audio signals as an intermediary carrier for payment information. Instead of direct cash exchange or complex electronic transactions, the payment data is encoded into audio messages that can be easily transmitted and decoded, simplifying the payment process.
2Reliability
If bank card payment is used, then payment security is improved, but the payee needs to install a point of sale (POS) machine which increases additional transaction cost
Solution Approach 1:
The patent extracts the core payment functionality from the POS machine requirement. By using audio-based communication between mobile devices, the system removes the need for expensive POS terminals while retaining secure payment capabilities through existing smartphone hardware.
Solution Approach 2:
The patent utilizes inexpensive, widely available smartphone devices instead of expensive POS machines. The payment functionality is implemented through software on existing mobile devices that users already carry, eliminating the need for costly dedicated payment terminals.
3Reliability
If bank card payment is used, then payment reliability is improved, but payment by bank card may yet to be implemented in some scenarios such as taking subway, a self-service ticketing bus, or a taxi
Solution Approach 1:
The patent creates a universal payment system that works across multiple scenarios including subway, bus, taxi, and retail transactions. The audio-based payment method can be implemented on any smartphone regardless of location, making it adaptable to various payment contexts where traditional bank card systems may not be available.

AI summary
A method, device and system of completing payment through clients are disclosed. The method includes a first client being a payee and a second client being a payer. The first client performs audio encoding on: a first client identifier and obtained pending payment charge indication information in order to obtain a computed payment charge voice message, subsequently broadcasts the computed payment charge voice message. The second client performs: monitoring the computed payment charge voice message subsequently decodes the computed payment charge voice message to extract the first identifier and the pending payment charge indication information; generates a payment request and sends to a server the payment request including the first identifier, the pending payment charge indication information and payer information. The server: initiates a payment transaction process to complete funds transfer between a payer account corresponding to the payer information and a payee account corresponding to the first client identifier.
