Shared Wallet Directory for Multi-Issuer Online Checkout

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional online checkout systems require users to input card details for each transaction, which can be cumbersome due to the need to manage multiple cards from different issuers across various merchants, each with their own checkout systems.

Innovation Solution

A computer-implemented method and system that utilizes a shared wallet directory to receive a unique user identifier, determine associated cards from multiple issuers, and send identifying information to enable card selection for transactions, obtaining a payment authorization token to process payments across different merchants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If users provide card details for each transaction at different merchants, then each merchant can process payments, but users experience repeated manual input and reduced checkout efficiency

Engineering Contradiction:

Improvecheckout efficiencyVSAvoidtime for repeated card input

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary action by storing card details in a wallet directory before transactions occur. During checkout, the pre-stored card information is automatically retrieved and presented to the user for selection, eliminating the need for repeated manual card input at each merchant.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a wallet directory as an intermediary component that mediates between the user's card information and multiple merchant systems. This intermediary stores and manages card details, allowing seamless interaction with different merchants without direct user input of card details each time.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If users store card information with each merchant, then future checkouts are faster at that merchant, but users must manage multiple stored card profiles across different merchants

Engineering Contradiction:

Improvecard selection convenienceVSAvoidnumber of checkout systems to manage

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple card profiles from different merchants into a single unified wallet directory. This consolidation allows users to manage all their card information in one place rather than maintaining separate stored profiles at each merchant, simplifying the overall system while maintaining ease of card selection.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The wallet directory is designed as a universal system that can store and manage card information from multiple issuers and work with multiple merchants. This multi-functional approach allows a single wallet to serve all transaction needs across different merchants, eliminating the need for merchant-specific card storage.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a shared wallet system is implemented across multiple issuers, then card management is simplified, but system architecture becomes more complex

Engineering Contradiction:

Improvemulti-issuer card supportVSAvoidwallet directory system architecture

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wallet directory acts as an intermediary layer between multiple card issuers and the user interface. This mediator handles the complexity of multi-issuer card management, token generation, and merchant communication, allowing the system to support multiple issuers without exposing the architectural complexity to users or merchants.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method including receiving a unique identifier for a user. The method also can include determining, using a wallet directory, a shared wallet associated with the unique identifier. The shared wallet can include identifying information for cards issued from multiple different issuers. The method additionally can include sending the identifying information for the cards to enable the user to select one of the cards for a first transaction at a first merchant. The method further can include obtaining information about a first selected card of the cards based on a selection from the user. The method additionally can include requesting a first payment authorization token for the first selected card from a wallet network system. The method further can include sending the first payment authorization token to enable the first merchant to process the first transaction using the first selected card. Other embodiments of related systems and methods are described.
