Animated QR Code Frames for Seamless Online Offline Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic financial transactions using QR codes, client devices often fail to determine whether to present a small, easily-scannable QR code for online transactions or a large, harder-to-scan QR code for offline transactions, leading to scanning difficulties and trust issues between client and merchant devices.
Innovation Solution
A computerized tool generates video/animated QR codes that decompose a QR code into a static fragment for online transactions and dynamic fragments for offline transactions, allowing the QR code to be rendered as a series of frames that can be scanned selectively by merchant devices based on their capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a QR code contains a larger amount of information for offline transactions, then trust establishment is improved, but scanning difficulty increases
Solution Approach 1:
The patent divides the QR code into multiple segments or frames, where each frame contains a subset of the total information. The merchant device can selectively scan one or more frames depending on whether online or offline transaction is needed, avoiding the need to scan the entire large QR code while still accessing the required information.
Solution Approach 2:
The patent implements a dynamic QR code system where the QR code can adaptively change its content or presentation based on the transaction type. The system dynamically selects which frames to display or which information subsets to prioritize, allowing the QR code to optimize between information completeness and scanability in real-time.
2Ease of operation
If a QR code contains a smaller amount of information for online transactions, then scanning ease is improved, but trust establishment deteriorates
Solution Approach 1:
The patent segments the QR code information into multiple frames, allowing the merchant device to scan only the necessary subset for online transactions (improving ease of operation) while the complete information remains available in the full set of frames for offline transactions requiring higher trust establishment.
Solution Approach 2:
The patent creates a universal QR code system that can serve both online and offline transaction types using the same underlying structure. The multi-frame design allows the QR code to be universally applicable to different transaction scenarios, with the merchant device adapting its scanning strategy based on the transaction type.
3Adaptability or versatility
If the client device presents a QR code without knowing the transaction type, then adaptability is improved, but scanning reliability deteriorates
Solution Approach 1:
The patent implements a dynamic adaptation mechanism where the QR code system can respond to different transaction types without requiring the client device to know the type in advance. The merchant device dynamically determines whether to perform online or offline transaction and accordingly scans the appropriate frames, making the system adaptable while maintaining reliability.
Solution Approach 2:
The patent introduces a feedback mechanism where the merchant device receives information about the available frames and can determine the appropriate scanning strategy. This feedback loop allows the system to adapt to different transaction types while ensuring reliable scanning by matching the scanning approach to the actual transaction requirements.

AI summary
Systems/techniques that can facilitate video/animated QR codes are provided. In various aspects, a processor can identify a QR code. In various instances, the processor can decompose the QR code into a static fragment and a plurality of dynamic fragments. The static fragment can be a portion of the QR code that contains sufficient information to facilitate an online transaction, whereas the plurality of dynamic fragments can be a plurality of portions of the QR code that collectively contain sufficient information to facilitate an offline transaction. In various instances, the processor can sequentially render a plurality of frames on an electronic display, where each frame depicts the static fragment and a corresponding one of the plurality of dynamic fragments. Accordingly, a point-of-sale device can facilitate an online transaction by scanning one frame rendered by the processor, and/or can facilitate an offline transaction by scanning all frames rendered by the processor.
