Flexible Web Orifice for Secure Payment Terminal Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current payment terminals lack the capability to securely integrate cash register functions and ensure accurate, visible display of transaction information, making them vulnerable to fraud and non-compliance with PCI standards.
Innovation Solution
A secure system is implemented using a flexible web with an orifice to apply pressure on a metal contact dome, forming a gangue around a deformable pressurizing element, which detects attempts to dismantle or alter the terminal, ensuring secure data transmission and visibility of the second display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a second display screen is added to the terminal to show transaction information, then the visibility and readability of transaction data is improved, but the security of the terminal is worsened due to increased vulnerability to fraud and PCI compliance issues
Solution Approach 1:
The patent implements a nested security structure where a flexible web with orifice is positioned over the second display screen, creating layers of protection. The deformable pressurizing element is nested within the flexible web structure, and the entire assembly is integrated into the terminal housing. This nested arrangement allows the screen to be visible and functional while multiple protective layers prevent unauthorized access and tampering, thus maintaining both visibility and security.
2Ease of operation
If the terminal is made portable and compact, then the ease of operation and usability is improved, but the security protection capability is worsened due to reduced space for security features
Solution Approach 1:
The patent employs a flexible web with orifice as a thin film security feature that can be integrated into the compact terminal structure. This flexible web provides security protection without requiring significant space, as it can be laminated or attached to existing terminal components. The deformable pressurizing element also utilizes minimal space while providing effective security through its pressure-sensitive detection capability. This allows the terminal to maintain portability and compactness while incorporating robust security features.
3Reliability
If the flexible web orifice diameter is made smaller than the metal contact dome diameter, then the security detection capability is improved, but the manufacturing precision requirement is worsened
Solution Approach 1:
The patent specifies precise dimensional parameters for the flexible web orifice and metal contact dome, with the orifice diameter being smaller than the dome diameter. This parameter relationship is carefully defined to ensure proper security detection functionality. The invention accepts the resulting manufacturing precision requirements as necessary to achieve the enhanced security detection capability, where the specific size relationship between orifice and dome enables detection of unauthorized access attempts while maintaining functional integrity.
