Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional online checkout processes are cumbersome due to the need to input card details for each transaction, especially when dealing with multiple cards from different issuers across various merchants, leading to a fragmented and inefficient user experience.

Innovation Solution

A computer-implemented method and system that provides a shared wallet interface, allowing users to obtain a unique identifier, receive an authentication code, and select a card from a list of cards issued by multiple different issuers for processing transactions, streamlining the checkout process across multiple merchants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users provide card details for each transaction at different merchants, then each merchant can process payments, but the checkout process becomes cumbersome and time-consuming

Engineering Contradiction:

Improvecheckout processVSAvoidtime for card input

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system segments the payment process by separating card management from transaction processing. Users store card details once in a wallet system, which then segments and manages multiple cards from different issuers. During checkout, only card selection is needed rather than full card details, reducing repetitive input.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by having users store card details in advance in a wallet system before actual transactions. This pre-storing of card information eliminates the need for repeated card input during checkout, saving time while maintaining payment processing capability.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If users manage multiple cards from different issuers across various merchants, then payment flexibility is improved, but the complexity of managing and selecting cards increases

Engineering Contradiction:

Improvepayment optionsVSAvoidwallet management system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wallet system achieves universality by being able to store and manage cards from multiple different issuers in a single interface. This multi-functional wallet can handle various card types and issuers, providing payment flexibility while consolidating management into one system rather than requiring separate management for each card or merchant.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The wallet system acts as an intermediary between users and multiple card issuers. It mediates the complexity by providing a unified interface that abstracts away the underlying complexity of managing multiple cards from different issuers, allowing users to select and use cards without directly dealing with each issuer's system.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If merchants implement their own separate checkout systems, then each merchant can customize their process, but users experience a fragmented checkout across different websites

Engineering Contradiction:

Improvemerchant checkout customizationVSAvoiduser experience consistency

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The wallet system provides universality by serving as a common payment interface that works across multiple different merchant websites. Each merchant can maintain their own checkout system, but the wallet provides a consistent, standardized interface for card selection and payment management that works universally across all participating merchants.

Inventive Principle:

Principle #6Universality (Multi-functionality)

A method including obtaining a unique identifier for a user. The method also can include causing an authentication code to be sent to a device of the user. The method additionally can include receiving, through a first user interface displayed to the user, the authentication code. The method further can include displaying, to the user through the first user interface, a list of cards in a shared wallet for the user. The cards can be issued from multiple different issuers. The shared wallet can be accessible to multiple different merchants. The method additionally can include receiving, through the first user interface displayed to the user, a selection from the user of a selected card from the list of the cards for processing a transaction. The method further can include providing card information for the selected card to a merchant for processing the transaction. Other embodiments of related systems and methods are described.
