Smartphone Attendance Verification via GPS and Triangulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current payroll management systems struggle to accurately monitor attendance and calculate wages for employees working in varied and remote locations, particularly for blue-collar workers, due to complex overtime rules and differing state and local regulations, leading to onerous data recording and potential fraud.
Innovation Solution
A smartphone-based attendance management system that allows employees to clock in and out, using GPS, triangulation, and Wi-Fi connectivity to verify their location, with data transmitted to a payroll company's server for accurate time tracking and reporting, reducing workers' compensation liabilities and preventing under-the-table payments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If employees manually record attendance data for various locations and time codes, then payroll calculations can be performed, but the data recording process becomes onerous and error-prone
Solution Approach 1:
The system enables employees to automatically clock in and out using their smartphones, with the system automatically capturing location data and time information. This eliminates the need for manual data recording by employees, as the system serves itself by automatically gathering and processing attendance data.
Solution Approach 2:
The patent replaces manual mechanical data entry with automated electronic systems. Smartphones with GPS, accelerometers, and network connectivity automatically capture location, time, and activity data, substituting the manual recording process with electronic automation.
2Adaptability or versatility
If software is installed on networked computers for clocking events, then attendance data can be collected centrally, but employees working outside office environments cannot use the system
Solution Approach 1:
The system uses smartphones as universal devices that employees already carry regardless of work location. The smartphone serves multiple functions: GPS location tracking, accelerometer-based activity detection, network communication for data transmission, and user interface for clocking events, making the system adaptable to any work environment.
Solution Approach 2:
The smartphone acts as an intermediary device between the employee and the central payroll system. It captures local data (location, time, activity) and communicates with the central server, enabling employees to clock in/out anywhere with network connectivity without requiring software installation on work computers.
3Measurement precision
If multiple location tracking methods are used (GPS, triangulation, Wi-Fi), then location verification accuracy improves, but system complexity increases
Solution Approach 1:
The system merges multiple location tracking technologies (GPS, Wi-Fi triangulation, cellular tower triangulation) into a unified location verification system. The smartphone integrates these different methods and the server combines their data to determine employee location, achieving high accuracy through combination rather than relying on a single complex system.
Solution Approach 2:
The system changes parameters such as acceptable distance thresholds and signal strength requirements based on the work location type and payroll rules. This allows the same location verification system to adapt to different environments (office, construction site, remote location) without increasing structural complexity.

AI summary
A system verifies whether or not an employee is actually on a job at a location during a standard time period, such as a work shift, by sending alerts to the employee's smart phone. The employee must respond to the alerts. The alerts are sent at random time intervals with a certain average rate. The average rate, called a Poisson parameter, can be varied over the course of a shift.
