Dynamic Integrated Barcode for Secure Payment Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current payment systems using integrated barcodes are vulnerable to security issues and are time-consuming due to the need for manual barcode scanning at point-of-sale terminals.
Innovation Solution
A payment service method and apparatus that generates a dynamically changing integrated barcode, valid for a preset time, combining personal and product barcode information, including payment means such as credit cards, discount cards, and account transfer information, to facilitate rapid and secure transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a static integrated barcode is stored in a mobile device for payment, then payment convenience is improved, but security vulnerability increases
Solution Approach 1:
The patent transforms the static barcode into a dynamic one by introducing time validity parameters. The integrated barcode is generated only for the current time moment and automatically becomes invalid after a preset time period, preventing unauthorized reuse while maintaining payment convenience through automatic expiration
Solution Approach 2:
The patent changes the temporal parameter of the barcode from static to dynamic by adding time validity attributes. The barcode includes time information and is configured to be valid only within a specific time window, fundamentally altering its security characteristics while preserving ease of use
2Measurement precision
If manual barcode reading is performed at POS terminal for each product, then payment accuracy is improved, but transaction time increases
Solution Approach 1:
The patent merges multiple functions into a single integrated barcode that combines product identification, payment method selection, and discount card information. This consolidation allows the POS terminal to process all payment-related information in one scan, eliminating the need for multiple manual readings while maintaining payment accuracy through the integrated data structure

AI summary
Provided are a payment service system, a payment service apparatus and method thereof. A personal barcode is issued for each user, an integrated barcode is generated by mapping the personal barcode with a product barcode, and the integrated barcode is changed for a preset period by setting the integrated barcode to only be valid during a preset period when performing a payment using the integrated barcode. Accordingly, security can be improved.
