POS App Deployment via Pre-Validation and Tokenization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current payment processing systems using mobile devices as point-of-sale terminals face challenges in ensuring the security and compliance of POS applications, particularly in handling sensitive payment card data, which can lead to vulnerabilities and non-compliance with PCI requirements.
Innovation Solution
The deployment of POS applications on payment terminals involves scanning for security and compliance, cryptographic signing, and verification to ensure integrity, followed by controlled deployment using a deployment plan, which includes tokenization of payment data to prevent exposure to merchant systems and maintain PCI compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If POS applications are deployed directly to mobile payment terminals without scanning and verification, then deployment speed and ease of operation are improved, but security and compliance reliability deteriorate
Solution Approach 1:
The system performs preliminary scanning, security verification, and cryptographic signing of POS applications before deployment to mobile payment terminals. This advance preparation ensures that only secure and compliant applications are deployed, resolving the contradiction by maintaining high deployment speed while ensuring security and compliance reliability through pre-validation mechanisms
2Reliability
If POS applications are scanned and cryptographically signed before deployment, then security and compliance are improved, but device complexity and processing time increase
Solution Approach 1:
The system introduces an intermediary server that centralizes the scanning, security verification, and cryptographic signing processes for POS applications. This intermediary handles the complex security operations remotely, reducing the complexity burden on mobile payment terminals while maintaining high security and compliance standards through centralized control
3Productivity
If payment card data is processed directly through merchant systems, then processing efficiency is improved, but PCI compliance and security are worsened due to data exposure
Solution Approach 1:
The system extracts sensitive payment card data from merchant systems and routes it through a dedicated payment processing application that communicates directly with the payment gateway. This extraction removes sensitive data exposure from merchant systems, maintaining PCI compliance while preserving processing efficiency through direct payment gateway communication
