Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attendance management systems are vulnerable to fraud, as employees can pretend to be each other by using each other's mobile terminals, leading to inaccurate recording of arrival and leaving times and stock reports, which can result in errors and extra work.
Innovation Solution
An attendance management system that includes a processor controlling the display of arrival and leaving screens on a mobile terminal, where arrival date and time are input before stock reports, and leaving date and time are input after stock reports, ensuring that employees cannot input stock information without first arriving and vice versa, and utilizing a server to manage and associate arrival/leaving information with stock data across multiple ECRs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If employees use mobile terminals for attendance registration, then convenience and ease of operation are improved, but vulnerability to fraud and reliability deteriorate
Solution Approach 1:
The system requires employees to perform stock input operations before attendance registration. This preliminary action ensures that only employees who have actually performed work (and thus know the stock status) can register their attendance, preventing fraud where employees might use each other's devices without having been present or worked
Solution Approach 2:
The system provides feedback by requiring verification of work performance (through stock input) before allowing attendance registration. This feedback mechanism ensures that the attendance record is tied to actual work performed, enhancing reliability while maintaining the convenience of mobile terminal usage
2Reliability
If stock input is required before attendance registration, then fraud prevention and reliability are improved, but processing time and loss of time worsen
Solution Approach 1:
The system merges the stock input operation with the attendance registration process into a single integrated workflow. By combining these two operations, employees complete both tasks in one sequence without requiring separate time allocations, thus maintaining reliability while minimizing time loss
Solution Approach 2:
Stock input is performed as a preliminary action that naturally occurs during the workday before attendance registration. Since employees must already be present and working to input stock data, this preliminary action does not add significant time burden but ensures reliability of the attendance record

AI summary
An attendance management device including a processor which performs control to: display a date and time reception screen for receiving a predetermined operation timing by a user as arrival date and time or leaving date and time; and display a stock input screen for a user to input a stock in a predetermined sales data processing device or a predetermined drawer device, wherein the processor performs control to display the date and time reception screen prior to displaying of the stock input screen when an arrival processing mode is selected, and the processor performs control to display the date and time reception screen after displaying of the stock input screen when a leaving processing mode is selected.
