Electronic Receipt Issuing via Server Address and NFC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face difficulties in managing paper receipts, which can lead to personal information leakage, and businesses incur additional costs for printing and managing paper receipts.
Innovation Solution
A method for issuing electronic receipts that involves generating a unique address corresponding to transaction information, storing it on a server, and transmitting it to a user's device via wireless communication, allowing users to access the receipt through a browser without installing a separate app, using technologies like NFC for easy data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paper receipts are used for transaction records, then consumers can receive physical proof of purchase, but consumers face difficulties in managing paper receipts and there is a risk of personal information leakage
Solution Approach 1:
The patent replaces physical paper receipts with electronic copies stored on servers and accessible via mobile devices. The e-receipt system creates digital replicas of transaction records that can be viewed, stored, and managed electronically, eliminating the need for physical paper handling while maintaining proof of purchase functionality
Solution Approach 2:
The patent substitutes the mechanical paper-based receipt system with an electronic information system. Instead of physical printing and manual management, the system uses digital storage, wireless transmission, and mobile device access to deliver and manage receipt information, replacing the mechanical paper handling process
2Reliability
If paper receipts are printed and managed, then consumers receive transaction proof, but businesses incur additional costs for printing and managing paper receipts
Solution Approach 1:
The system creates electronic copies of transaction records stored on servers, replacing physical paper production. This eliminates printing costs, paper consumption, and physical storage requirements while maintaining the validity and proof function of receipts through digital access
Solution Approach 2:
The patent eliminates the need for physical paper disposal and storage management by transitioning to electronic storage. The system recovers resources by eliminating paper production, printing materials, and physical storage space requirements while maintaining receipt functionality
3Ease of operation
If e-receipts are accessed through a browser without installing a separate application, then user convenience is improved, but additional security measures are needed to ensure secure access
Solution Approach 1:
The patent uses a server as an intermediary between the transaction system and the user's mobile device. The server stores transaction information and delivers it via wireless communication to the mobile device, acting as a secure intermediary that manages data transmission without requiring direct application installation on the user device
Solution Approach 2:
The system uses a universal web browser interface that works across different mobile devices without requiring device-specific applications. This multi-functional approach allows any mobile device with a browser to access e-receipts, improving convenience while the server manages security centrally

AI summary
Provided is a method of issuing an electronic receipt, which enables a user to conveniently check an electronic receipt through a smartphone. The method of issuing an electronic receipt includes receiving, by an electronic receipt generator, information regarding a transaction from a point of sale (POS) terminal, generating an address corresponding to the information, and storing transaction information in a server corresponding to the address; transmitting the generated address to a user device through a near-field wireless communication technology; and displaying, by the user device, an electronic receipt through the transmitted address.
