QR Code Payment System Using Inverted Scanning and Intermediary Servers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing payment systems lack security and practicality, as they often require sharing personal and financial data, which is vulnerable to breaches, and traditional methods like cash and checks are inconvenient and insecure.
Innovation Solution
A system using QR codes to facilitate secure fund transfers by scanning the merchant's QR code, leveraging cryptographic processes and multiple servers to ensure the consumer's data remains secure, with the merchant's QR code being scanned instead of the consumer's, and utilizing a network of databases to maintain autonomy and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional payment methods (cash, check, credit card) are used, then payment transactions can be completed, but security risks increase due to exposure of personal and financial data
Solution Approach 1:
The patent extracts sensitive personal and financial data from the payment transaction process. Instead of transmitting actual account information, the system uses QR codes containing only account identifiers, and processes transactions through a intermediary server that never stores or transmits sensitive data, effectively removing the data security vulnerability from the payment flow
Solution Approach 2:
The patent introduces a intermediary payment processing server that acts as a mediator between sender and recipient. This server handles the sensitive data processing, verification, and fund transfer without exposing account information to the merchant or other parties, creating a secure intermediary layer that protects user data while enabling transactions
2Ease of operation
If consumer's QR code is scanned for payment, then transaction can be initiated, but consumer's personal and financial data becomes vulnerable
Solution Approach 1:
The patent inverts the traditional QR code scanning approach. Instead of the consumer displaying and having their QR code scanned (which would expose their data), the merchant displays their QR code and the consumer scans it. This reversal maintains payment convenience while protecting consumer data, as the merchant's QR code contains no sensitive consumer information
3Productivity
If financial data is stored on retailer's platform, then transactions can be processed quickly, but security vulnerabilities increase in case of database breach
Solution Approach 1:
The patent extracts sensitive financial data from the retailer's database entirely. The system uses a centralized payment processing server that stores encrypted account information and handles all transaction processing, while the retailer's platform only stores non-sensitive order information. This separation maintains fast transaction processing while eliminating the security vulnerability of storing financial data on retailer systems
Data Source
AI summary
Systems and methods for processing encoded symbols to facilitate secured communication between a mobile device and one or more database systems is provided. Communication between the mobile device and the database systems is performed to update database tuples in the database systems based on processing of the encoded symbols. The encoded symbols may correspond to QR codes and updating database systems may include administering quick response (QR) code-enabled payment transactions.
