Solution Overview

Problem

Configuring POS terminals and business applications to accept and process payment transactions is complex and time-consuming, requiring sophisticated programming knowledge and network certification, which is also cumbersome.

Innovation Solution

A transaction management controller manages payment authorization request messaging by receiving transaction amounts and card data from a business management engine and a point of interaction device, inserting this data into a payment authorization request message, and transmitting it to a payment network, while being communicatively isolated from the business management engine, and controlling POI device features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional POS terminals and business applications are configured to support and communicate with various different payment networks and card readers, then payment processing capability is improved, but device complexity and configuration time increase significantly

Engineering Contradiction:

Improvepayment processing capabilityVSAvoidconfiguration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a transaction management controller as an intermediary component that sits between the business application and the payment terminal hardware. This controller handles the complexity of communicating with different payment networks and card readers, while presenting a simplified interface to the business application. The controller acts as a mediator that translates between the simple business logic layer and the complex payment processing layer, thereby resolving the contradiction between versatility and configuration complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system is segmented into distinct functional layers: the business application layer, the transaction management controller layer, and the payment terminal hardware layer. Each layer has specific responsibilities and interfaces with the next layer through well-defined protocols. This segmentation allows the business application to remain simple while the transaction management controller handles the complexity of supporting multiple payment networks and devices, thus resolving the contradiction between adaptability and configuration complexity.

Inventive Principle:

Principle #1Segmentation

2Reliability

If POS terminals require certification by various payment networks, then payment security and compliance are improved, but certification time and process complexity increase

Engineering Contradiction:

Improvepayment securityVSAvoidcertification time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The transaction management controller is designed with multi-functionality to support multiple payment networks and communication protocols simultaneously. By implementing a universal controller that can handle different network requirements through software configuration rather than hardware changes, the system reduces the need for separate certifications for each network. The controller's ability to adapt to different networks through configuration rather than physical modification streamlines the certification process while maintaining security requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If sophisticated programming knowledge is required to configure POS terminals and business applications, then payment processing functionality is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvepayment processing functionalityVSAvoidconfiguration ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The transaction management controller serves as an intermediary that shields the business application from complex programming requirements. It provides pre-configured interfaces and handles the sophisticated communication protocols with payment networks automatically, allowing business applications to use simple, standardized interfaces while still achieving complex payment processing functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The transaction management controller implements self-service capabilities by automatically managing configuration settings, network communications, and device interactions. Rather than requiring manual programming of each payment network protocol, the controller self-configures and handles the complex operations autonomously, thereby improving ease of operation while maintaining full payment processing functionality.

Inventive Principle:

Principle #25Self-service

AI summary

Technologies for managing payment authorization request messaging for payment transactions include a transaction management controller for receiving a transaction amount for a payment transaction from a business management engine and payment card data for the payment transaction from a point of interaction device. The transaction management controller inserts the transaction amount and the payment card data into a payment authorization request message, which is transmitted to a payment network. A payment authorization response message is received from the payment network and transmitted by the transaction management controller the business management engine. Other embodiments are described and claimed.
