Mobile scanner solution for gas stations with offline data capture and synchronization

A mobile scanner solution was developed for operational processes at gas stations based on Xamarin.Android and C#/.NET. The goal was to map key inventory and operational workflows directly on mobile devices, even in environments without a stable backend connection.

The application supports multiple business processes such as deliveries, inventories, orders, corrections, and price changes. Data is stored locally on the device and synchronized with backend systems at a later stage. This ensures that staff can continue working reliably without depending on a constant online connection.

Interfaces are used to exchange data such as articles, deliveries, inventories, orders, corrections, price changes, and labels with the backend. Communication is secured using OAuth2 and bearer tokens. In addition, multilingual support, master data management, and device registration were implemented.

The solution is specifically designed for scanner/MDE hardware and connects mobile data capture seamlessly with existing administrative and inventory systems.

Benefits for operations

• Fully usable offline in unstable network conditions
• Reduced paperwork and manual follow-up
• Faster inventories, orders, and corrections
• Centralized synchronization with backend systems
• Improved data quality through structured scanning processes
• Multiple business processes handled within a single app
