SmartPass Campus - RFID
An end-to-end RFID access control ecosystem that bridges edge hardware with a full-stack web application via MQTT, delivering secure, real-time identity verification and centralized database management.
Overview
Developed as a comprehensive web technology and database management sessional initiative, this project modernizes campus access by integrating physical hardware with cloud-based administrative services. A dedicated microcontroller reads RFID tags via the I2C protocol and transmits instantaneous scan telemetry to a centralized backend using lightweight MQTT messaging. The system features a custom-built, secure web dashboard utilizing JWT authentication, allowing administrators to execute seamless CRUD operations against a MongoDB database. The entire hardware array was protected within a custom enclosure, and the software lifecycle was driven by structured Agile and Waterfall methodologies in a collaborative team environment.
Key Technical Achievements
Hardware Interfacing & Telemetry
Engineered the physical access terminal by interfacing a microcontroller with an RFID module via I2C, transmitting low-latency scan data to the backend infrastructure using MQTT protocols.
Full-Stack Web Security
Architected an administrative web portal secured by JWT authentication, ensuring that administrative access and sensitive student access logs were heavily protected against unauthorized entry.
Database Management & API Design
Implemented robust backend architecture to handle comprehensive CRUD (Create, Read, Update, Delete) operations, utilizing MongoDB to efficiently index and query daily access logs and user credentials.
Structured Team Delivery
Managed the end-to-end project lifecycle within a collaborative team setting, applying a hybrid of Agile and Waterfall methodologies to align hardware deployment, custom enclosure fabrication, and software milestones.
