Clock In Out

Overview

The clock-in/out system outlined here offers an innovative approach to managing employee attendance using modern web technologies and hardware integration. By leveraging NestJS as the backend framework alongside Angular for the frontend, this project creates a seamless experience for users and administrators alike. The system is designed not only to track the clock-in and clock-out times but also to make use of NFC technology via Arduino to streamline the process, ensuring quick and efficient user interactions.

With a focus on real-time data transmission using RxJS, the system maintains a level of responsiveness ideal for attendance tracking in dynamic environments. This project emphasizes good coding practices and architecture, allowing it to scale and include additional features in the future, such as an admin panel for enhanced user management and monitoring.

Features

• NFC Integration: Utilizes Arduino as an NFC transmitter, allowing users to clock-in and clock-out simply by scanning their ID cards for ease and speed.
• NestJS Backend: Built on the NestJS framework which promotes scalable and maintainable application development using familiar Angular principles.
• PostgreSQL Database: Employs PostgreSQL with TypeORM for structured data management, ensuring reliable storage of user attendance records.
• Real-Time Capabilities: Implements RxJS for nearly real-time updates on the frontend, providing users with quick feedback without the need for complex socket implementations.
• Angular Frontend: Features a responsive Angular frontend that supports easy scaling for future enhancements, maintaining a user-friendly interface.
• Future-Ready Architecture: Designed with the possibility of expanding features, such as an admin panel for user and attendance management, to improve overall functionality.
• Simple Communication Protocol: Uses standard HTTP POST requests for communication between Arduino and the backend, ensuring straightforward implementation.
