## Overview

The product is a Laravel attendance-management web application for recording employee work time and time off. The main workflow is administrative: manage employees and schedules, collect attendance from biometric devices, and review attendance and related reports. The README establishes these product goals; the tree identifies the corresponding controllers, models, and views. Sampled device-controller code confirms device interaction and attendance/leave persistence, but the other controllers and route definitions were not sampled, so their detailed wiring is not inferred.

Main entry points: [`routes/web.php`](https://github.com/aliatayee/attendance_management_system/blob/master/routes/web.php) (Web routes), [`app/Http/Controllers/BiometricDeviceController.php`](https://github.com/aliatayee/attendance_management_system/blob/master/app/Http/Controllers/BiometricDeviceController.php) (Device management), [`app/Http/Controllers/EmployeeController.php`](https://github.com/aliatayee/attendance_management_system/blob/master/app/Http/Controllers/EmployeeController.php) (Employee management), [`config/database.php`](https://github.com/aliatayee/attendance_management_system/blob/master/config/database.php) (Application database)
