Stack Used

• Frontend:
  • HTML5/CSS3/JavaScript
  • Bootstrap 5 for responsive design
  • SignaturePad.js for digital signatures
  • AJAX for real-time updates
  • October CMS Twig templating
• Backend:
  • PHP 8.1
  • October CMS (Laravel-based)
  • MySQL database
  • RESTful API endpoints

Key Features

1. Real-time Check-in/Check-out Interface

2. Digital Signature Capture

3. Attendance Report Generation

4. Authorization Management

Technical Challenges Solved

1. Multiple Check-ins Per Day

Challenge: Supporting multiple entries and exits while maintaining accurate time calculations.

Solution: Implemented a sophisticated tracking system that:
