Manage parking transparently in seconds.

---

🧠 Overview

ParkFlow is a QR-based digital parking management system designed to eliminate manual logging, reduce fraud, and provide real-time parking visibility.

It replaces traditional paper-based parking systems with a secure, fast, and transparent digital workflow.

---

🎯 Problem Statement

Traditional parking systems suffer from:

• ❌ Manual vehicle logging (slow & error-prone)
• ❌ Paper-based records
• ❌ No real-time slot tracking
• ❌ Revenue mismanagement risks
• ❌ No centralized dashboard
• ❌ Difficult auditing process

🚨 Impact

Manual entry takes 2–3 minutes per vehicle.
In busy lots, this leads to:

• Long queues
• Poor tracking
• Revenue leakage

💡 Our Solution

ParkFlow digitizes the entire workflow using QR technology.

🔄 System Flow

1. User scans QR at parking entry
2. System verifies authentication
3. Slot is automatically assigned
4. Entry time is logged
5. Dashboard updates in real time
6. On exit → duration & fee calculated automatically

✨ The Magic Moment

User scans QR → instantly sees
“Parking Slot Assigned – Slot B12”

Fast. Transparent. Frictionless.
