Smart Mess Attendance System

📘 About the Smart Mess Attendance System

The Smart Mess Attendance System is a student-friendly and admin-accessible digital solution built for BIT Mesra hostel messes. This system eliminates the need for manual registers or ID card scanning by leveraging face/photo verification and Gmail login integration.

🔹 Key Features:

Students login with their official Gmail ID (e.g., btech10XYZ.24@bitmesra.ac.in) and generate a mess ticket once per meal.
Maximum 4 tickets can be generated per day — for Breakfast, Lunch, Snacks, and Dinner.
Every ticket generation immediately displays the student’s photograph for mess gate verification.
Each ticket is timestamped and linked to the student’s Gmail and roll number.
Students can download their monthly CSV showing present/absent records and total meals taken.
Admin can edit student attendance count for the current day and download hostel-wise CSVs.
Admin panel allows uploading new student JSON data (data/hostelX.json) to Firestore.

🔹 Usage Flow:

Landing screen shows a hostel selection grid (Hostel 1 to Hostel 13).
Students click “Student Login”, select their hostel, and sign in using their BIT Gmail.
Post-login, student sees only their name, roll, and “Generate Ticket” button (disabled after 4 meals).
On ticket generation, the student photo appears, and the count updates in Firebase.
Refreshing or closing the page logs the student out, preventing multiple ticket claims or proxy.

🔹 Admin Features:

Admin can log in via Gmail and access the admin panel before or after login.
They can view and edit any student’s attendance count of the current day.
Admins can select a hostel and download full monthly attendance CSV with row-wise student data.
They can upload hostel student data from data/hostelX.json to Firebase in one click.
Only authorized Gmail IDs are allowed as admins (set in Firestore under /admins collection).

🔒 Security Measures:

Only authenticated users can read/write attendance data.
Admins are separately verified via Firestore rules and can’t be spoofed from frontend.
Each ticket is linked with timestamp, email, and student photo — reducing misuse.
No silent login — every time the student logs in, Gmail selection prompt appears.
Photo is only shown after ticket generation to avoid unnecessary preloading or exposure.

📌 Final Note:

This system ensures fairness, transparency, and ease for mess staff and students alike. It can run on a low-cost mobile device placed at the mess entrance. The platform is entirely web-based and optimized for mobile and desktop.
