Overview
My Auchan, a Russian retail client, needed to integrate barcode and QR code scanning capabilities into its existing mobile application. The existing application was developed using Xamarin, so the key requirement was to add scanning functionality without making major changes to their existing technology stack.
Scanflow provided a Barcode & QR Code Scanning SDK that could be integrated directly into the My Auchan mobile application, giving the app native scanning capability without a broader rebuild.
Business Challenge
No Native Scanning Capability in the Existing App My Auchan’s mobile application had no built-in way to scan barcodes or QR codes, limiting what customers and staff could do directly in the app.
02
Adding Scanning Couldn’t Disrupt the Existing Tech Stack The application was built on Xamarin, and any scanning solution needed to integrate without requiring major changes to that existing stack.
03
The App Later Needed to Migrate Frameworks Without Losing Scanning Functionality When My Auchan moved its application from Xamarin to .NET MAUI, the scanning capability needed to carry over without disruption to the business requirements it already supported.
The Scanflow Solution
Scanflow provided a Barcode & QR Code Scanning SDK that could be integrated directly into the My Auchan mobile application. Initially, Scanflow provided a Xamarin SDK for barcode and QR code scanning. Later, when My Auchan migrated its application from Xamarin to .NET MAUI, Scanflow updated the solution and provided the Scanflow Barcode SDK for .NET MAUI. The SDK enables the application to scan and process both barcodes and QR codes while continuing to support the client’s existing business requirements.
Barcode & QR Code Scanning SDK
The SDK adds native barcode and QR code scanning directly into the My Auchan mobile application.
Xamarin Integration
Scanflow’s initial SDK was built for Xamarin, integrating with My Auchan’s application as it existed at the time.
.NET MAUI Migration Support
When My Auchan migrated its application to .NET MAUI, Scanflow updated the SDK accordingly, carrying scanning functionality forward without disruption.
On-Device Processing
Scanning and processing happen directly on the customer’s mobile device, using its existing camera.
Business Impact
By integrating a software-only scanning SDK that adapted alongside My Auchan’s own technology migration, My Auchan added scanning capability to its app without a stack rebuild or new hardware.
Key Outcomes
Scanning added without a stack rebuild — the SDK integrated directly into the existing Xamarin application.
No new hardware needed — scanning uses the device’s own camera.
Future-proofed through the framework migration — Scanflow updated the SDK to match My Auchan’s move to .NET MAUI.
No data retention risk — Scanflow does not store any scanned data, in the cloud or otherwise.
Delivery Footprint
Software-only SDK — no separate hardware provided or required
Supported across My Auchan’s application framework, from Xamarin through the migration to .NET MAUI
All scanning and processing on-device, with no Scanflow-side data storage
Conclusion
My Auchan added native barcode and QR code scanning to its mobile app without disrupting its existing technology stack or requiring new hardware. Scanflow’s SDK integrated directly into the original Xamarin application and was seamlessly updated to .NET MAUI when My Auchan migrated its platform — all while processing scans entirely on-device, with no data stored by Scanflow. The result is a scanning capability that evolved alongside My Auchan’s own technology roadmap, with zero disruption to the customer experience.
