Payment Terminal With Segmented Transactional And Cumulative Storage Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current payment terminals lack the capability to handle cash register functions, leading to fraud and errors in transaction logging, particularly when cash registers malfunction or are tampered with for fraudulent purposes, and there is a need for a solution to integrate secure and efficient accounting and tax management within the terminal.
Innovation Solution
A payment terminal integrating cash register functions with specific storage modules, including an extractable transactional storage module and a cumulative storage module, along with a dual display system and secure assembly mechanism to prevent tampering, allowing for secure and visible transaction recording and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cash register is connected to a payment terminal, then transaction data can be transmitted and received, but the cash register may malfunction or be tampered with, leading to inaccurate payment logs and potential fraud
Solution Approach 1:
The patent divides the storage function into two separate modules: a transactional storage module for individual transaction records and a cumulative storage module for totalized amounts. This segmentation ensures that if one module fails or is tampered with, the other can still provide accurate data, thereby resolving the contradiction between reliability and vulnerability to fraud.
Solution Approach 2:
The patent extracts the storage function from the cash register system and integrates it directly into the payment terminal. By incorporating dedicated storage modules within the terminal itself, the system eliminates dependence on external cash registers that may malfunction or be tampered with, thus improving reliability while reducing fraud risk.
2Ease of repair
If the transactional storage module is made extractable, then it can be replaced when full without replacing the entire terminal, but this may compromise terminal security
Solution Approach 1:
The patent applies different security characteristics to different parts of the storage system. The transactional storage module is designed to be extractable and replaceable for ease of maintenance, while the cumulative storage module remains fixed and secured within the terminal. This local differentiation of security properties allows the system to maintain overall security while enabling easy replacement of the transactional module when full.
3Loss of information
If dual display screens are added to show transaction data, then visibility and transparency are improved, but device complexity increases
Solution Approach 1:
The patent designs the display system so that the dual screens serve multiple functions: they display transaction details for customer verification, show cumulative totals for accounting purposes, and can potentially display instructional information. By making the display system multi-functional, the patent justifies the increased complexity through enhanced versatility and information transparency.
