Common Purchasing Interface for Cross-App In-App Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current application distribution platforms lack a streamlined mechanism for users to purchase in-app products across multiple applications with varying pricing and currency support, requiring users to repeatedly enter payment information and offering limited flexibility in pricing strategies for developers.
Innovation Solution
An in-app purchasing system that allows users to purchase digital content and additional features through a common interface, supporting multiple currencies and pricing strategies, with automatic currency conversion and incremental price adjustments, while simplifying the process for developers to manage and display prices across different currencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a common purchasing interface is implemented across multiple applications, then user convenience is improved by eliminating repeated payment entry, but device complexity increases due to currency conversion and pricing management mechanisms
Solution Approach 1:
The patent implements a universal purchasing interface that serves multiple applications across different devices. This common interface handles payment processing, currency conversion, and pricing display uniformly across the application ecosystem, eliminating the need for separate payment mechanisms in each application and thereby improving user convenience while managing complexity through standardization
Solution Approach 2:
The patent introduces an intermediary purchasing system that sits between the user and multiple applications. This intermediary layer manages currency conversion, stores payment information securely, and coordinates pricing across applications, thereby simplifying the user experience while containing complexity in a dedicated intermediate component rather than分散 across all applications
2Adaptability or versatility
If multiple currencies and pricing strategies are supported, then adaptability is improved for global users, but device complexity increases due to currency conversion and price management mechanisms
Solution Approach 1:
The purchasing interface is designed to universally support multiple currencies and pricing strategies across all applications. It automatically detects user location, converts prices to local currencies using current exchange rates, and displays appropriate pricing formats, thereby providing global adaptability through a single multi-functional system rather than requiring separate implementations for each currency
Solution Approach 2:
The system dynamically changes pricing parameters based on user location, selected currency, and current exchange rates. Prices are automatically adjusted and recalculated in real-time without requiring manual intervention or complex configuration in each application, thereby achieving currency adaptability through parameter-driven automation rather than hard-coded multi-currency support
3Ease of operation
If automatic currency conversion is implemented, then ease of operation is improved for users, but loss of information increases due to exchange rate fluctuations and conversion timing
Solution Approach 1:
The system performs preliminary currency conversion at the point of purchase rather than at the point of pricing display. When a user initiates a purchase, the system locks in the current exchange rate and completes the conversion at that moment, thereby eliminating uncertainty about exchange rate fluctuations and ensuring accurate pricing information is preserved from display through transaction completion
Solution Approach 2:
The purchasing system continuously monitors exchange rates and provides feedback to update displayed prices in real-time. Before finalizing a purchase, the system confirms the current exchange rate and converted price with the user, allowing them to verify the conversion and making any necessary adjustments, thereby preventing information loss through transparent feedback loops

AI summary
In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products. A first third-party application program that was developed by a first entity receives a first request to purchase a first product for use within the first third-party application program. In response to receiving the first request, a purchasing user interface is customized to include first details that are specific to the first product. The purchasing user interface that includes the first details is displayed. A second request to purchase a second product for use within the second third-party application program is received from a second third-party application program that was developed by a second entity. In response to receiving the second request, the purchasing user interface is customized to include second details that are specific to the second product. The purchasing user interface that includes the second details is displayed.
