Runtime NFT Promotion Placeholders for Fraud-Resistant QR Payments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional QR code payment systems lack proactive fraud prevention mechanisms, leading to fraudulent transactions and missed opportunities for customer engagement and promotion through personalized offers.
Innovation Solution
Implementing extemporaneously concealed non-fungible token (NFT) promotion placeholders in QR codes, which are filled with targeted marketing content and transaction-specific information at runtime, ensuring only authorized devices can complete the QR code for secure transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional QR code payment systems are used, then transaction speed and ease of operation are improved, but security against fraudulent transactions deteriorates
Solution Approach 1:
The system performs preliminary verification by analyzing the QR code structure and validating promotion placeholders before the transaction is executed. The server verifies the authenticity of promotion placeholders and generates verification codes in advance, preventing fraudulent transactions before they occur rather than detecting them after the fact.
Solution Approach 2:
A server acts as an intermediary between the client device and the QR code payment system. The server receives QR codes, verifies their authenticity by checking promotion placeholders, generates verification codes, and communicates with merchant systems to validate transactions. This intermediary layer adds security without significantly impacting transaction speed.
2Reliability
If QR codes contain only transaction information, then security is improved, but customer engagement and marketing opportunities are lost
Solution Approach 1:
The QR code is segmented into multiple functional components: transaction information fields and promotion placeholder fields. The promotion placeholders are further segmented into specific positions that can be independently verified and filled with different marketing content. This segmentation allows the system to maintain security through verification while enabling versatile marketing engagements.
Solution Approach 2:
The QR code structure is designed to serve multiple functions simultaneously: it contains transaction information for secure payments and includes promotion placeholders for marketing campaigns. The verification mechanism works universally for both security validation and marketing content authentication, allowing a single QR code to fulfill both security and engagement purposes.
3Reliability
If QR codes are verified in real-time, then fraud prevention is improved, but transaction processing time increases
Solution Approach 1:
The system performs preliminary verification of the QR code structure, including validation of promotion placeholder positions and formats, before the transaction is executed. The server generates verification codes in advance based on the analyzed QR code, so that when the transaction occurs, the verification can be completed quickly using pre-generated codes rather than performing full analysis in real-time.
Solution Approach 2:
The verification process focuses on specific critical elements of the QR code rather than analyzing the entire code uniformly. The system specifically targets promotion placeholder positions and verification codes for detailed validation, while other parts of the QR code are processed more quickly. This localized verification approach maintains security while reducing overall processing time.

AI summary
A method for inserting a plurality of promotion placeholders into a quick response (“QR”) code. The method may include generating an inactive QR code, using a first device. The inactive code may include an algorithmic code and the promotion placeholders. The method may scan the inactive QR code using a second device. The method may send the scan to a QR analyzer. The QR analyzer may interpret the algorithmic code to identify a plurality of non-fungible tokens (“NFTs”) for filling the promotion placeholders. The method may generate the NFTs and complete the inactive QR code to form a complete QR code. The methods may include filling the promotion placeholders with the NFTs and interpreting the complete QR code. Interpreting the complete QR code may include executing a transaction between the first device and the second device. The methods may include adjusting the transaction based on information interpreted from the NFTs.
