Unified ID Conversion for Multi-System Transaction Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer-based commerce systems require separate user IDs and 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 across multiple transaction systems by capturing product codes using a portable device, generating transaction files, and converting IDs for electronic receipt storage and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate authentication processes are established for each transaction system, then system security is improved, but operation convenience deteriorates
Solution Approach 1:
The patent implements a universal authentication mechanism where a single user ID registered in the self-registration system can be used across multiple transaction systems including electronic receipt systems. The system establishes equivalence relationships between different user IDs, allowing one authentication to validate access across multiple systems, thereby maintaining security while improving convenience.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism that mediates between different transaction systems. When a user ID from the self-registration system is used in another system, the system verifies equivalence through an intermediary process that checks predefined equivalence relationships, enabling cross-system authentication without requiring separate login processes for each system.
2Adaptability or versatility
If multiple user IDs are required for different transaction systems, then system independence is improved, but processing speed deteriorates
Solution Approach 1:
The patent establishes equivalence relationships between user IDs in advance during system setup or initial registration. This preliminary action creates a lookup table of equivalent user IDs, so that during actual transactions, the system can quickly verify authentication by simple table lookup rather than performing complex cross-system verification, thereby improving processing speed while maintaining system independence.
3Adaptability or versatility
If separate authentication processes are used for each system, then system modularity is improved, but customer convenience deteriorates
Solution Approach 1:
The patent merges the authentication functions of multiple transaction systems by establishing equivalence relationships between their user IDs. The self-registration system's authentication mechanism is combined with electronic receipt systems and other transaction systems, allowing customers to use a single registered user ID across all systems, thereby improving convenience while preserving the modular architecture of individual systems.

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.
