Mobile Barcode Payment Generation and Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile payment systems using mobile devices are cumbersome, time-consuming, and prone to fraudulent transactions due to the need for users to manually enter information and manage multiple payment methods.
Innovation Solution
A mobile application generates a barcode that can be scanned for payment, allowing users to securely and efficiently transfer funds from their account to a merchant's account, with features for refund transactions and generation of virtual debit/credit cards, coupons, and gift cards, utilizing existing scanning systems with minimal modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually enter payment information through web browsers on mobile phones, then payment functionality is achieved, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent uses barcode technology to create a visual copy of payment information that can be scanned and processed automatically. Instead of manually entering payment details, the system generates a barcode representation of the payment data, which is then read by a scanner to complete the transaction, dramatically reducing the time and effort required for payment.
Solution Approach 2:
The patent replaces the manual mechanical process of typing payment information with an automated optical scanning system. The barcode generation and scanning process substitutes the manual keyboard input mechanism with an automated image recognition and data processing system, eliminating the need for users to physically enter payment details.
2Reliability
If traditional mobile payment methods are used, then payment capability is provided, but the system becomes prone to fraudulent transfers
Solution Approach 1:
The patent implements preliminary verification actions by requiring users to authenticate and generate barcodes only after proper identification and authorization. The system performs preliminary checks including user verification, account validation, and transaction authorization before the actual payment occurs, preventing fraudulent transfers by ensuring only authenticated users can initiate payments.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system provides immediate confirmation and verification information to both the user and the merchant during the transaction process. The barcode generation includes verification data, and the scanning process provides real-time feedback on transaction validity, allowing the system to detect and prevent fraudulent attempts through immediate verification responses.
3Adaptability or versatility
If users manage multiple physical payment methods, then various payment options are available, but the process becomes cumbersome
Solution Approach 1:
The patent creates a universal barcode-based payment system that can represent multiple payment methods and transaction types through a single interface. The barcode generation system can encode different payment information (credit card, debit card, gift card, etc.) using the same mechanism, allowing users to access various payment options without managing separate physical cards or complex systems.
Solution Approach 2:
The patent uses barcode copying to represent multiple payment methods digitally. Instead of carrying multiple physical payment cards, users generate barcode copies of their payment information that can be scanned and processed. This digital copying approach consolidates multiple payment methods into a single manageable system while maintaining versatility.
Data Source
AI summary
An application on user's mobile device (having a display screen) generates a one-time use and time-limited barcode on the display when the user enters a PIN. The barcode can be scanned to make purchases at a point of sale (POS).
