Multi-Funding Source Payment Allocation via Account Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic payment systems are inflexible and inefficient, limited to one-to-one transactions between a single user and a merchant, due to the rigid nature of payment networks and merchant systems, which restricts the ability to process multi-funding source transactions.
Innovation Solution
A card system that utilizes a single card linked to multiple funding sources, accessing an account mapping to determine transaction proportions and generate authorization messages for processing multi-funding source transactions, allowing for secure, flexible, and efficient transactions within existing payment network and merchant infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional one-to-one payment systems are used, then transaction processing is simple and reliable, but the system lacks flexibility and cannot support multi-funding source transactions
Solution Approach 1:
The patent introduces a payment management system as an intermediary layer between the user and the payment networks. This mediator receives transaction requests, determines the appropriate funding sources based on account mappings, and coordinates with multiple payment networks simultaneously, enabling multi-funding transactions without requiring changes to the underlying rigid payment network infrastructure.
Solution Approach 2:
The patent segments the payment processing into distinct functional components: account mapping maintenance, funding source determination, transaction authorization, and coordination with multiple payment networks. This segmentation allows each component to be optimized independently while working together to achieve flexible multi-funding transactions.
2Adaptability or versatility
If payment networks and merchant systems are modified to support multi-funding transactions, then transaction flexibility improves, but implementation difficulty and cost increase due to hardware and software changes
Solution Approach 1:
The payment management system acts as an intermediary that shields the merchant and payment networks from the complexity of multi-funding logic. The intermediary handles account mappings, funding source selection, and coordination with multiple networks, allowing merchants to continue using existing simple payment terminals without hardware or software modifications.
Solution Approach 2:
The patent creates a virtual representation of the payment account structure through account mappings that link user accounts to multiple funding sources. This virtual copying of the payment hierarchy allows complex multi-funding transactions to be processed through standard payment interfaces without requiring physical changes to payment terminals or network infrastructure.
3Productivity
If a single card is linked to multiple funding sources, then transaction efficiency improves, but account management complexity increases
Solution Approach 1:
The account mapping system automatically determines the appropriate funding sources and their proportions based on pre-configured rules and account relationships. The system self-manages the complexity of multi-account coordination without requiring user intervention during transactions, allowing users to simply present a single card while the system handles the underlying complexity of multiple funding sources.
Solution Approach 2:
The patent establishes account mappings and funding source preferences in advance, before transactions occur. This preliminary configuration allows the system to quickly determine appropriate funding sources during transactions without real-time complex calculations, significantly improving transaction processing speed while maintaining the ability to handle multiple funding sources.

AI summary
This disclosure describes methods, non-transitory computer readable storage media, and systems that utilize a card to provide multi-funding source payment transactions between a plurality of users and a merchant system. For example, in response to a request to process a multi-funding source transaction for a card in connection with a merchant system, the disclosed system accesses an account mapping to determine whether to process the transaction utilizing a plurality of funding sources associated with the card (e.g., based on transaction attributes or merchant attributes). The disclosed system also utilizes the account mapping to determine proportions for processing the transaction with the plurality of funding sources. Additionally, the disclosed system generates authorization messages to send to one or more payment networks for processing the multi-funding source payment transaction utilizing the plurality of funding sources for specific payment amounts based on the proportions.
