Mobile Device Barcode Display for Secure Transaction Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for online purchases that require printed receipts can be inconvenient when the receipt is lost, stolen, or misplaced, as merchants may not accept transactions without visual inspection or charge validation fees.
Innovation Solution
A portable communication device that receives a barcode image from an online system, allowing for visual inspection or processing by a point of sale device to complete the purchase fulfillment process, enabling secure and efficient transaction validation without physical receipts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a printed receipt is used for online purchase fulfillment, then the transaction can be authenticated by the merchant, but the receipt can be lost, stolen, or misplaced causing inconvenience
Solution Approach 1:
The patent replaces the physical printed receipt with a digital barcode that can be displayed on a mobile device screen. This digital copy maintains all the authentication functionality of the printed receipt while eliminating the risks of loss, theft, or misplacement associated with physical documents. The barcode serves as a virtual replica that can be easily presented and re-presented without degradation.
Solution Approach 2:
The patent substitutes the mechanical/physical system of printed paper receipts with an electronic display system. Instead of relying on physical paper that can be damaged or lost, the system uses a mobile device's display to present the barcode, thereby eliminating the physical vulnerabilities while maintaining the authentication mechanism.
2Reliability
If a printed receipt is required for purchase fulfillment, then the merchant can validate the transaction, but the consumer may be required to pay a validation fee or face delays
Solution Approach 1:
The digital barcode replaces the physical receipt, enabling faster electronic validation by the merchant. The barcode can be instantly scanned and verified through the online system, eliminating the manual validation processes that require additional time and may incur fees.
Solution Approach 2:
The system implements real-time feedback between the merchant's POS device and the online system. When the barcode is scanned, the system immediately verifies its authenticity and provides feedback on the transaction status, enabling rapid validation without manual intervention or additional fees.
3Reliability
If visual inspection of a printed receipt is used, then the merchant can authenticate the transaction, but the process is time-consuming and may require validation fees
Solution Approach 1:
The patent replaces manual visual inspection with automated optical scanning of the barcode. The POS device's scanner rapidly reads the barcode and electronically verifies it with the online system, transforming a time-consuming manual process into an automated, high-speed electronic validation process.
Solution Approach 2:
The digital barcode serves as a machine-readable copy of the transaction information, replacing the human-readable printed receipt that requires visual inspection. This enables automated scanning and verification, dramatically increasing transaction processing speed while maintaining authentication reliability.
