Unified ID Conversion for Multi-System Transaction Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer-based commerce systems require separate authentication processes for each system, making it inconvenient to use multiple systems in a single purchase transaction.
Innovation Solution
A method that integrates a self-registration system with an electronic receipt system, allowing customers to use a single user ID and enabling the conversion of self-registration IDs to electronic receipt IDs for seamless transaction processing across multiple systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate authentication processes are used for each transaction system, then system security and independence are maintained, but customer convenience and processing speed deteriorate due to multiple logins required
Solution Approach 1:
The patent implements a universal authentication system where a single user ID registered with one transaction system (e.g., self-registration system) can be used across multiple transaction systems (e.g., electronic receipt system, POS system). The authentication information is stored centrally and made accessible to multiple systems, allowing one authentication process to serve multiple functions and systems, thereby eliminating the need for separate logins while maintaining system independence and security.
2Productivity
If multiple user IDs are required for different transaction systems, then system independence is preserved, but transaction processing time increases due to multiple authentication steps
Solution Approach 1:
The patent implements preliminary action by having customers register a single user ID in advance through the self-registration system. This pre-registered authentication information is then stored and made available for use across multiple transaction systems. When the customer makes a purchase, the authentication is already completed from the preliminary registration, eliminating the need for time-consuming re-authentication at each transaction point and significantly reducing processing time.
3Adaptability or versatility
If separate authentication systems are used for self-registration and electronic receipt systems, then system modularity is maintained, but operational efficiency decreases due to inability to use single ID across systems
Solution Approach 1:
The patent introduces an intermediary mechanism that bridges the self-registration system and the electronic receipt system. This intermediary allows authentication information from one system to be recognized and utilized by the other system without compromising their individual modular structures. The intermediary enables seamless interaction between systems, allowing customers to use a single ID across different transaction systems while maintaining the operational independence and adaptability of each system.
Data Source
AI summary
A method of processing a purchase transaction includes generating a transaction file containing a product code, which is transmitted from a user computing device when an image of a product code identifier is captured by the user computing device, a first user ID of the customer, and an indicator of whether or not the customer has opted in to receive electronic receipts. The method further includes generating an electronic receipt based on the transaction file, storing a conversion table containing the first and second user IDs of the customer, converting the first user ID contained in the transaction file to the second user ID based on the conversion table, when the indicator indicates that the customer has opted in, and storing the electronic receipt in association with the second user ID. The electronic receipt is transmitted in response to a request for electronic receipts associated with the second user ID.
