The organization required a secure mobile application to manage QR-code based operational workflows, including activation, validation, and revocation. Existing processes required controlled access, real-time synchronization, and reliable status management for field operators while preventing unauthorized use.
Mobile
Flutter QR Code Validation App with Firebase
Bugs Monkey designed and developed a secure Flutter mobile application for QR code activation, validation, and status management using Firebase. The system supports controlled access, real-time status updates, and risk-aware operational workflows without public user registration.
The challenge
⚠ Problem
The client needed a secure operational mobile application capable of managing QR code lifecycles while supporting authenticated access, real-time validation, and immediate synchronization across devices. The solution also needed to eliminate public registration and reduce operational errors during field usage.
✓ Approach
Bugs Monkey developed a Flutter mobile application backed by Firebase Authentication and Cloud Firestore. The solution introduced PIN-based authentication, QR code activation and validation workflows, real-time status synchronization, risk-aware state management, and a clean modular architecture designed for operational reliability.
Background
A secure Flutter application that delivers fast, reliable QR validation workflows with real-time synchronization and controlled user access.
— Bugs Monkey TeamWhat we built
The project included a Flutter mobile application integrated with Firebase Authentication and Cloud Firestore, featuring PIN-based login, QR code activation and validation, real-time status updates, lifecycle management for QR codes, and a modular architecture designed for scalability and long-term maintenance.
