Money Processing System Cross-Terminal Access Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional money processing systems restrict bank employees from accessing idle money handling devices from any terminal device, even if they are available for use, unless they are specifically set up for that terminal.
Innovation Solution
A money processing system that includes a terminal device with a user information storage unit and a match judging unit to authenticate and establish connections with idle money handling devices, allowing bank employees to access available devices for deposit or withdrawal requests, while ensuring security through user authentication and port management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one money handling device is set for a terminal device, then security and device reliability are improved, but adaptability and ease of operation deteriorate because employees cannot access idle devices from other terminals
Solution Approach 1:
The patent implements a universal access mechanism where any terminal device can access any money handling device through authentication. The terminal device transmits user information to the money handling device, and if authentication succeeds, the connection is established regardless of traditional one-to-one pairing. This makes the system multi-functional in terms of access patterns.
Solution Approach 2:
The terminal device acts as an intermediary that mediates access between users and money handling devices. It transmits user information to the money handling device and manages the connection establishment process, enabling flexible access while maintaining security through centralized control.
2Device complexity
If multiple terminal devices are restricted to specific money handling devices, then device complexity is reduced, but productivity deteriorates due to idle devices cannot be utilized
Solution Approach 1:
The system transitions from static one-to-one device pairing to dynamic many-to-many access. Terminal devices can dynamically connect to any money handling device based on availability and authentication, allowing flexible resource allocation that improves productivity without significantly increasing system complexity.
Solution Approach 2:
The system implements feedback mechanisms where terminal devices receive connection status information from money handling devices. This allows terminals to identify and connect to available devices, optimizing resource utilization and productivity through informed decision-making.
3Adaptability or versatility
If authentication mechanisms are added to enable cross-terminal access, then adaptability improves, but device complexity increases due to additional security components
Solution Approach 1:
The authentication system operates autonomously where the terminal device itself transmits and verifies user information without requiring additional external authentication hardware. The terminal and money handling device perform mutual verification, reducing the need for complex centralized authentication infrastructure.
Data Source
AI summary
A money processing system includes a terminal device that stores therein as user information, a terminal user identifier for identifying a user and a code used for confirming the user for security reasons entered by the user, judges whether the received user information matches the stored user information when the user information that is entered at a money handling device is received through a port used for data communication with the money handling device, and establishes a connection with the money handling device from which the user information was received via the port if the pieces of the user information match, and the money handling device for entering the user information.
