Centralized Electronic Receipt Aggregation System

Solution Overview

Problem

Customers face inconvenience in checking their purchase history across multiple electronic receipt services, as they need to access each service separately, leading to increased time and effort.

Innovation Solution

An information providing apparatus that collects and aggregates electronic receipt data from multiple data management systems, allowing users to view their transaction history in a unified interface through a communication interface, storage device, and processor, using a receipt client app to input and process commodity codes and transaction data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If customers check purchase history at each electronic receipt service separately, then they can access complete transaction data, but the time and effort required increases significantly

Engineering Contradiction:

Improvepurchase history informationVSAvoidtime to check purchase history

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent merges multiple electronic receipt services into a single unified service that consolidates transaction data from multiple sellers. The system combines receipt management functionality into one platform, allowing customers to view all purchase history across different sellers without accessing multiple separate services, thus resolving the contradiction between information completeness and time efficiency

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The unified electronic receipt service performs multiple functions: it manages receipts from multiple sellers, provides centralized purchase history tracking, and offers a single interface for accessing transaction data across different commercial entities. This multi-functional approach eliminates the need for separate service access while maintaining comprehensive information availability

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Loss of information

If customers check purchase history at each electronic receipt service separately, then they can access complete transaction data, but the operational complexity increases

AI summary

In accordance with an embodiment, a communication interface, an input device, and a processor are provided. The processor collects electronic receipt data containing a commodity code for identifying an already traded transaction target commodity from a plurality of data management apparatuses via the communication interface. The processor generates history data on the basis of the collected electronic receipt data, the history data indicating a transaction history of the commodity identified by the commodity code acquired via the input device.
