Cashless Payment Terminal Using Optical Recognition for Automatic Amount Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cashless payment systems require users to perform cumbersome operations, such as inputting and correcting payment amounts, which are inconvenient and time-consuming, especially in scenarios with varying product prices, and lack adaptability between manned and unmanned stores.
Innovation Solution
A cashless payment system utilizing an information terminal with a camera that photographs a QR code containing payment destination information and a displayed purchase amount, automatically processing the payment after recognizing these elements, thereby eliminating the need for user input and simplifying the payment process across different store attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the user scanning method with fixed QR code is used, then the introduction cost is low, but the user must perform manual input and correction operations for payment amount
Solution Approach 1:
The system enables automatic payment processing by having the terminal device capture images of both the QR code and price information display, then automatically extract and process the payment amount without requiring user input or correction operations
Solution Approach 2:
The manual mechanical operation of typing and correcting payment amounts is replaced by an automated optical recognition system that uses image capture and processing to automatically obtain price information from the display
2Ease of operation
If the store scanning method is used, then the payment processing is automated, but the introduction cost of equipment on the store side increases
Solution Approach 1:
Instead of requiring expensive store-side scanning equipment, the system uses the terminal device's camera to capture images of the QR code and price display, creating a visual copy of the information that can be processed without specialized hardware
Solution Approach 2:
The terminal device performs multiple functions including camera capture, image processing, QR code reading, and payment processing, eliminating the need for dedicated store-side scanning equipment by making the terminal device universal for these tasks
3Adaptability or versatility
If manual input operation is required for payment amount, then the system can handle various payment scenarios, but the payment time and user convenience are reduced
Solution Approach 1:
The system performs preliminary capture of the price information display image before the payment process, so that the payment amount is already extracted and ready for processing, eliminating the need for manual input during the payment transaction
Solution Approach 2:
The system continuously captures and processes the price information from the display throughout the interaction, ensuring that the payment amount is always available and ready for immediate processing without interruptions for manual input

AI summary
A technique in which with respect to cashless payment technique, suitable cashless payment can be carried out with less operation by a user who is a purchaser is provided. An information terminal is configured to: photograph, by a camera, a code of payment destination information posted by a store and a payment amount corresponding to a purchase amount of a product or service on a basis of an operation of a user; issue a payment command in a case where both payment destination information and the payment amount are recognized on a basis of a photographed image, the payment command including the payment destination information and the payment amount; and transmit the payment command to a server to cause the server to execute the cashless payment processing.
