HR System for Fingerprint Attendance and Payroll
An on-premises HR system for fingerprint attendance, live staff monitoring, payroll calculations, and employee self-service.
Key results
Attendance and payroll in one system
Live visibility of staff on-site
Employee self-service records

Summary
We built an on-premises HR system around fingerprint clock-in data. A live screen shows who is on-site, payroll is calculated from attendance records, and employees can view their own hours and pay through a dedicated dashboard. The system runs on the company server so staff data stays in the building.

The situation
Attendance and payroll records were difficult to keep together.

The business needed a more reliable way to manage attendance, staff presence, and payroll. Manual records made it hard to see who was on-site and forced the owner to answer routine questions about hours and pay.
The result
Attendance and payroll in one system
The company gained a single place to review attendance, staff presence, and payroll information. Employees could check their own records, while the owner had a clearer view of daily workforce activity without relying on paper records or a separate per-seat service.
Additional outcomes
- Live visibility of staff on-site
- Employee self-service records
