Shield Food Locker

PagerTec approached ITzak Technologies to build a reliable, hardware-integrated mobile application for its Shield Food Locker ecosystem. The primary requirement was to ensure seamless and uninterrupted locker operations in real-world food service environments where internet availability could not be guaranteed.

We designed and developed a native Android application that communicates directly with Shield Food Locker hardware to control locker bays. The application supports essential workflows such as opening and closing bays, depositing food orders, and securely picking up food — all performed completely offline.

The system supports two user roles: Owner and Customer. Owners (restaurant staff or administrators) manage locker availability and food deposits, while customers access assigned lockers to collect their orders securely. All actions are stored locally using offline storage, ensuring data integrity and operational continuity even during peak hours.

This offline-first architecture made Shield Food Locker a highly dependable solution for enterprise food delivery operations, enabling PagerTec to deploy the system across multiple restaurant locations with confidence.

We delivered

We delivered a native Android application built in Java that integrates seamlessly with Shield Food Locker hardware. The solution includes offline data storage, role-based user access, and secure locker bay control for food deposit and pickup without relying on network connectivity.

Our strategy focused on building an offline-first, hardware-driven architecture to guarantee reliability in high-traffic restaurant environments. We prioritized direct device-to-hardware communication, secure local data persistence, and fail-safe locker operations.

The application was designed with a clean, functional interface optimized for speed and clarity. The UI minimizes steps for both restaurant staff and customers, ensuring quick, error-free interactions even during busy service hours.

The Shield Food Locker application was developed using Java for native Android, with a strong emphasis on offline storage and direct hardware integration. The system manages real-time locker commands, user role workflows, and local transaction logging to deliver consistent performance and stability.
