QR Code Data Single-Use Processing and Deactivation Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current QR code technologies allow for multiple processing of data, enabling users to repeatedly use the same data, which can lead to misuse or unintended multiple uses, such as accumulating excessive loyalty points or repeated phone top-ups.
Innovation Solution
A method for single-use processing of QR code data involves scanning, decoding, analyzing, and deactivating the data within an IT system to ensure it can only be used once, preventing further processing after initial use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If QR code data is designed for multiple processing, then data reusability and flexibility are improved, but system security and control over usage are worsened
Solution Approach 1:
The system performs preliminary verification of QR code data validity and usage status before processing. The server checks whether the data has been previously used, expired, or is still valid, and only allows processing if the verification passes. This preliminary action prevents unauthorized reuse while maintaining legitimate data reusability.
Solution Approach 2:
The system implements a feedback mechanism where the server responds to scanning devices with verification results indicating whether the QR code data can be processed. This feedback loop provides real-time usage control, informing the system state and enabling dynamic decision-making about data reusability based on current validity and usage history.
2Ease of operation
If QR code data allows repeated processing, then user convenience is improved, but potential for misuse and fraud is worsened
Solution Approach 1:
The server performs preliminary verification checks before allowing data processing, examining usage history, expiration dates, and validity status. This preliminary action maintains user convenience by allowing legitimate repeated use while preventing misuse through automated verification of usage rights.
Solution Approach 2:
The system provides feedback to scanning devices about the validity and usage status of QR code data, enabling users to understand why certain scans succeed or fail. This transparent feedback mechanism maintains ease of operation for legitimate uses while systematically preventing fraudulent repeated processing.
3Productivity
If QR code data is processed without verification, then processing speed is improved, but data integrity and security are worsened
Solution Approach 1:
The system performs preliminary verification of data integrity, expiration status, and usage history before processing. This preliminary check ensures data integrity is maintained while the verification process itself is optimized to minimize processing time, balancing speed with reliability.
Solution Approach 2:
The server provides feedback about data validity and processing authorization, enabling the scanning device to proceed or abort based on verification results. This feedback mechanism maintains processing speed by avoiding unnecessary operations on invalid data while ensuring data integrity through systematic verification.

AI summary
The method of single-use processing of data saved in a Quick Response (QR) code is the invention that consist in that, after scanning the QR code with a device equipped with a camera and extracting from it the data, the obtained data is analysed in order to check whether the data saved in the QR code have not been used already, and if it have not, the data is used in the IT system (for example mobile application, web application), and after that the data is deactivated, which prevent it from further usage. The invention can be used in loyalty program, because it allows for sending to the participants of the loyalty program cards containing the QR code, which, upon scanning, will grant to the user points in the loyalty program. Apart from that this invention make it also easier and faster to top-up phones.
