Multi-Channel Transaction Settlement for Fuel Discount Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Payment processors for fuel purchases lack flexibility due to limited data processing capabilities, requiring separate transactions for discounted and non-discounted products, and are restricted to single transaction channels, especially with legacy POS systems.
Innovation Solution
A multi-channel transaction settlement system that generates a single-use token for closed-loop transactions, processes data through both closed-loop and open-loop channels, and integrates with a financial system to facilitate seamless fund transfers across accounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If payment processors use legacy POS systems with single transaction channel, then system simplicity is maintained, but transaction flexibility and adaptability are limited
Solution Approach 1:
The system segments transaction processing into multiple independent channels (open-loop and closed-loop) that can operate simultaneously. Each channel is handled by separate processing logic within the payment processor, allowing the system to maintain simplicity within each channel while achieving overall versatility through the combination of channels.
Solution Approach 2:
The payment processor is designed with multi-functional capabilities to handle both open-loop transactions (via API interfaces) and closed-loop transactions (via POS systems). This universal design allows a single system to serve multiple transaction types and channels, improving adaptability without requiring separate dedicated systems for each transaction type.
2Adaptability or versatility
If payment processors accept only single transaction channel data, then processing simplicity is maintained, but transaction customization capability is reduced
Solution Approach 1:
The data processing architecture segments incoming transaction data based on channel type (open-loop vs. closed-loop). Each segment is processed according to its specific requirements, with dedicated parsing and validation logic. This segmentation allows the system to handle diverse data formats and requirements while maintaining processing simplicity within each data type.
Solution Approach 2:
The payment processor acts as an intermediary that receives, standardizes, and routes data from multiple transaction channels. It implements a universal internal data format that translates various external channel formats, enabling customized transaction processing without requiring complex direct integration with each channel's native format.
3Productivity
If purchasers must execute separate transactions for discounted and non-discounted products, then transaction accuracy is improved, but transaction efficiency and productivity are reduced
Solution Approach 1:
The system merges multiple transaction requests into a single consolidated transaction when they share the same purchaser account and merchant. The payment processor aggregates line items, applies appropriate discounts to each product category, and processes everything as one unified transaction. This merging maintains discount accuracy through itemized processing while significantly improving transaction efficiency by eliminating the need for separate transactions.

AI summary
A system is capable of settling both open-loop and closed-loop transactions originating at merchant systems. The system is configured to accept open-loop transactions using a payment network and for accepting closed loop transaction using a one-time use token generated by the system. The system is configured to settle transactions by applying discounts after final transaction data is generated—the discount may be determined for either closed-loop or open-loop transactions before deducting a discounted value from a purchaser's account.
