Biller Directory Architecture for Secure Payment Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bill payment infrastructures often operate in an uncoordinated or offline manner, lacking direct connectivity and efficient data exchange between financial institutions, leading to inefficiencies and increased costs due to the need for intermediaries in payment processing.
Innovation Solution
The implementation of biller exchange computing systems that enable direct interaction between financial institutions through a distributed application programming interface (API) system and synchronized biller directories, facilitating secure, real-time payments and reducing the reliance on third-party processors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional offline or uncoordinated payment processes are used, then financial institutions can maintain independent operations, but payment efficiency decreases and processing costs increase
Solution Approach 1:
Multiple financial institutions merge their biller directory operations into a single shared repository that is collectively maintained and updated by participating institutions. This consolidation eliminates redundant operations at each institution while enabling coordinated payment processing across the network, directly resolving the contradiction between improved productivity and reduced system complexity.
Solution Approach 2:
The shared biller directory serves multiple functions simultaneously: it acts as a centralized repository for biller information, a validation service for payment routing, and a coordination mechanism for inter-institutional transactions. This multi-functionality improves payment processing efficiency without proportionally increasing system complexity, as the same infrastructure supports multiple operational needs.
2Ease of manufacture
If third-party processors are used for payment coordination, then financial institutions can avoid direct connectivity infrastructure, but processing costs and intermediary dependencies increase
Solution Approach 1:
Financial institutions collectively maintain and operate their own shared biller directory infrastructure, eliminating the need for external third-party processors. Each participating institution contributes to and benefits from the shared system, performing payment coordination functions themselves rather than relying on external intermediaries. This self-service approach reduces processing costs by removing intermediary fees while maintaining implementation feasibility through standardized protocols.
3Speed
If direct connectivity between financial institutions is implemented, then payment processing speed improves, but system security requirements and implementation complexity increase
Solution Approach 1:
The shared biller directory acts as a trusted intermediary that enables secure direct connectivity between financial institutions. Rather than requiring each institution to establish direct secure connections with every other participant, the shared directory serves as a common reference point that validates payment routing information and facilitates secure transactions. This mediator approach maintains high processing speed through direct institution-to-institution payments while managing security through the centralized validation layer.
Data Source
AI summary
A payer computing system includes a processing resource, a memory resource, and computer-executable instructions stored thereon and embodied in a customer-side application programming interface (API). The instructions, when executed by the processing resource, cause the payer computing system to receive an electronic payment request and, in response, generate a request (e.g., a first API message) to access a biller computing system using a previously generated payer electronic token. The request is transmitted to the biller computing system. The payer computing system receives (e.g., via a second API message) payment information provided by the biller computing system in response to the request to access. Based on payment information, the payer computing system generates a payment transaction and causes (e.g., via a third API message) the payment transaction to be initiated.
