Proxy Payment Card Split Transaction System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional payment systems do not readily accommodate splitting of purchase transactions between multiple payment card accounts, making it cumbersome for users to split payments across different accounts, especially in retail settings.
Innovation Solution
A system that allows users to pre-configure a percentage split of transactions across multiple payment card accounts using a proxy payment card, which is issued with a unique proxy payment card number, enabling seamless split payments by presenting the proxy card at the point of sale, facilitated by a wallet services computer that generates authorization requests for each account based on the pre-set percentages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user wants to split a purchase transaction between multiple payment card accounts, then the payment flexibility and account utilization are improved, but the transaction complexity and operational difficulty increase significantly
Solution Approach 1:
The patent segments the single payment transaction into multiple sub-transactions, each charged to a different payment card account. The system divides the total purchase amount according to pre-configured percentage allocations and processes separate authorization requests for each account segment, enabling flexible payment distribution while maintaining systematic transaction management
Solution Approach 2:
The patent introduces an intermediary payment processing system that acts as a mediator between the point-of-sale terminal and multiple payment card accounts. This intermediary system receives the total transaction amount, applies the pre-configured split percentages, and automatically manages the complex coordination of multiple account charges, thereby simplifying the user experience while enabling versatile payment options
2Ease of operation
If a retailer accommodates split payments between multiple accounts, then customer service quality is improved, but the device complexity and processing requirements increase
Solution Approach 1:
The patent implements preliminary action by requiring customers to pre-configure their payment split preferences and associate multiple account numbers with specific percentage allocations before making purchases. This pre-configuration is stored in the payment terminal, allowing the system to automatically execute the predetermined split without requiring complex real-time processing or manual intervention during the actual transaction
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting the transaction amount parameter for each account based on the pre-configured percentage split. The system modifies the charge parameters automatically, routing different portions of the total transaction to different accounts according to the stored allocation ratios, thereby simplifying the processing logic while maintaining flexible payment capabilities

AI summary
A method includes receiving a first account indicator, where the first account indicator identifies a first financial account. The method further includes receiving a second account indicator, which identifies a second financial account. Still further, the method includes receiving a split signal, which indicates how future transactions are to be divided between the first financial account and the second financial account. The split signal may have been generated in response to interaction by an account holder with a slide-bar display element of a user interaction screen display.
