Receipt QR Review Verification for Authentic Consumer Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliance on online consumer reviews for purchasing decisions is compromised by the prevalence of fake reviews, which can unfairly influence sales and distort market perceptions, particularly for offline transactions that lack verification mechanisms.
Innovation Solution
Implementing a QR code or similar machine-readable code on transaction receipts or invoices that contains encoded transaction information, allowing users to verify the legitimacy of their purchase and compose verified reviews on multiple review platforms using a smartphone app, ensuring a unique and authenticated user identity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If online reviews are allowed without verification, then the ease of operation and quantity of reviews increase, but the reliability and authenticity of reviews deteriorate due to fake reviews
Solution Approach 1:
The patent introduces an intermediary verification system that uses machine-readable codes (QR codes, barcodes) on physical receipts as a mediator between the purchase transaction and the online review. This intermediary mechanism allows automated verification of purchase authenticity while maintaining ease of review posting, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The patent replaces manual verification mechanisms with automated optical scanning systems. Instead of requiring manual validation of purchase authenticity, the system uses smartphone cameras and optical code readers to automatically verify reviews through machine-readable codes, maintaining ease of operation while improving reliability.
2Reliability
If verification mechanisms are implemented for offline transactions, then the reliability of reviews improves, but the device complexity and implementation difficulty increase
Solution Approach 1:
The patent uses machine-readable codes (QR codes, barcodes) as simplified copies or representations of the actual purchase transaction data. Instead of implementing complex verification systems that access transaction databases directly, the system uses these code copies printed on receipts, which can be easily scanned and verified without complex infrastructure.
Solution Approach 2:
The patent changes the verification parameter from complex database authentication to simple optical code recognition. By encoding transaction verification information in machine-readable code format, the system reduces implementation complexity while maintaining verification reliability through widely available scanning technology.
3Quantity of substance
If multiple reviews are allowed per transaction, then the quantity and detail of feedback increase, but the reliability deteriorates due to potential flooding with fake reviews
Solution Approach 1:
The patent implements a feedback mechanism where the verification system provides real-time information about whether a review has already been submitted for a given transaction code. This feedback prevents duplicate reviews from the same transaction while allowing multiple legitimate reviewers to submit reviews, maintaining both quantity and reliability.

AI summary
A QR code on a receipt or invoice for a transaction facilitates a verified review for the transaction. The QR code or similar code contains information regarding the transaction and is printed on a review or invoice, such that a user wishing to write a review can scan the printed code such as with a camera and an app on a smartphone. The printed QR code comprises an encoded reference to a purchase and allows the user to employ the app (and/or a network-based service supporting the review app) to verify that a review has not yet been published for the purchase, and to compose a verified review for the purchase. The user may further select one or more review sites on which to publish the verified review, such as Google, Yelp, TripAdvisor, and the like, and publish the verified review on the selected review sites.
