Browser Plugin Digital Wallet with Rules-Based Funding Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital wallets provide limited functionality beyond storing and retrieving online shopping information, lacking features for efficient and secure management of account information during electronic commerce transactions.
Innovation Solution
A digital wallet system accessed via a browser plugin that stores and securely manages account information, allowing users to drag and drop or automatically populate funding source details on checkout pages, with rules-based selection of funding sources for specific purchases or merchants, and optional centralized trusted authority storage for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional digital wallets store only basic account information, then storage simplicity is maintained, but functionality and user convenience deteriorate
Solution Approach 1:
The digital wallet system is designed to perform multiple functions including storing account information, managing funding sources, processing transactions, and providing security credentials. This multi-functional approach resolves the contradiction by making the wallet versatile without proportionally increasing complexity, as these functions are integrated into a unified system architecture.
Solution Approach 2:
The wallet system is segmented into distinct components: account information storage, funding source management, transaction processing, and security credential management. This segmentation allows each component to be optimized independently, maintaining overall system manageability while providing comprehensive functionality.
2Productivity
If manual entry of account information is required, then data accuracy is maintained, but transaction speed and user convenience deteriorate
Solution Approach 1:
Account information and funding source details are pre-stored and organized in the digital wallet before transactions occur. This preliminary preparation eliminates the need for manual entry during transactions, simultaneously improving both transaction speed and user convenience while maintaining data accuracy through secure pre-validated storage.
Solution Approach 2:
The system automatically retrieves and populates account information from stored data without requiring manual user input. This self-service mechanism resolves the contradiction by enabling fast, convenient transactions while maintaining accuracy through automated data retrieval from pre-validated sources.
3Reliability
If centralized storage of sensitive information is implemented, then security is improved, but system vulnerability to attacks deteriorates
Solution Approach 1:
Sensitive information is segmented and distributed across multiple secure storage locations including local device storage and centralized secure servers. This segmentation reduces the vulnerability of any single storage point while maintaining overall security, as an attacker would need to compromise multiple distributed locations rather than a single centralized repository.
Solution Approach 2:
A trusted intermediary system manages the centralized storage and retrieval of sensitive information, providing security through controlled access mechanisms. This intermediary layer resolves the contradiction by enhancing security through professional security management while mitigating vulnerability through controlled access protocols and audit trails.
4Productivity
If rules-based automatic funding source selection is implemented, then transaction efficiency is improved, but control over payment selection deteriorates
Solution Approach 1:
The funding source selection system is designed to be dynamic and adaptable. Rules-based automatic selection operates efficiently for routine transactions, while the system allows users to dynamically adjust rules or override selections when needed. This dynamic approach resolves the contradiction by providing both automated efficiency and user control flexibility.
Solution Approach 2:
The system provides feedback mechanisms that allow users to review automatic funding source selections and adjust their preferences. This feedback loop resolves the contradiction by maintaining transaction efficiency through automated rules while preserving user control through the ability to modify rules and override selections based on user feedback.
Data Source
AI summary
A digital wallet may be accessed via a plugin on a browser. The digital wallet may store account information pertaining to various accounts of a user. The account information may be related to funding sources, reward programs, loyalty programs, retailers and other merchants, driver license information, voter registration information, government agencies, etc. The user may drag and drop account information from the digital wallet via the plugin to a checkout page or the plugin may automatically recognize and populate a checkout page. In an implementation, the plugin may select a funding source based on rules, such as use one funding source for payment of less than a predetermined amount and use another funding source for payment of at least the predetermined amount.
