POS Terminal Attendance Management via Intermediary Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current POS terminal systems lack the ability to effectively manage and utilize attendance information and cash drawer operations through external devices, limiting their integration and management capabilities in network systems.
Innovation Solution
An information processing device with an attendance manager database and a controller that communicates with external devices to manage attendance information and a cash drawer system, enabling remote control and data management through APIs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If attendance information is stored only in the POS terminal system, then the system maintains simple data storage, but external devices cannot access or utilize the attendance information
Solution Approach 1:
The patent introduces an intermediary component that bridges the POS terminal system and external devices. This intermediary enables attendance information to be accessed by external devices through standardized interfaces without requiring direct integration between all system components, thus improving accessibility while controlling complexity through modular architecture.
Solution Approach 2:
The patent implements a universal data access interface that allows multiple external devices to access attendance information through common protocols. This multi-functional interface serves various external devices (mobile devices, computers, servers) without requiring device-specific customization, thereby improving versatility while maintaining system simplicity.
2Adaptability or versatility
If the POS terminal system integrates cash drawer control, then operational functionality is improved, but system complexity increases
Solution Approach 1:
The patent merges cash drawer control functionality with the existing POS terminal system by integrating control commands into the transaction processing workflow. This combining approach allows operational functionality to be enhanced without requiring separate control systems, as the cash drawer is managed through the same interface that handles sales transactions.
Solution Approach 2:
The patent implements a universal control interface that handles both transaction processing and cash drawer operations through the same system architecture. This multi-functional interface allows the POS terminal to perform multiple functions (sales processing, attendance tracking, cash drawer control) without requiring separate dedicated systems for each function.
3Adaptability or versatility
If multiple printers are installed for different functions, then functional versatility is improved, but system complexity and management difficulty increase
Solution Approach 1:
The patent segments printing functions by dedicating specific printers to specific purposes (receipt printer for transactions, ticket printer for orders, attendance printer for employee records). This functional segmentation allows each printer to be optimized for its specific task while the central control system manages them through standardized interfaces, reducing management complexity despite having multiple devices.
Data Source
AI summary
Printed information related to attendance can be used through an external device. A control server has an attendance manager database storing attendance-related information based on print data instructing printing information related to attendance, and a control server controller. In response to a command from an management device, the control server controller executes a process using the attendance manager database, and sends information indicating the process result to the management device.
