Client
A US retailer selling printers and technical equipment, with an existing Magento e-commerce platform.
Workflow
In-store visitors scan a product’s barcode or QR code to see specs and pricing, add it to a cart, and check out without waiting for a sales associate.
Engagement
Chudovo built the scanning app for iOS and Android from the ground up and connected it to the client’s existing Magento backend and CyberSource payment processing, over 45 man-days.
Outcome
The client got a self-service, in-store buying flow instead of routing every purchase through a consultant.
Client
A German start-up (Hamburg) with its own self-scanning and mobile-checkout app already live in supermarket chains, including Edeka.
Workflow
Shoppers scan products as they shop, pay in the app, and exit through a fast lane by scanning a generated checkout barcode.
Engagement
Chudovo joined the client’s existing Xamarin codebase to add new features, refactor code, localize the app, introduce user roles and permissions, and build out unit tests, over 70 man-days.
Outcome
The updated app helped the client expand beyond supermarkets into other physical-checkout retail formats.
Retail-Workflow-First Design
Chudovo designs scanner applications around the actual retail workflow — how shoppers move through a store, how store associates handle inventory tasks, how self-checkout validation works.
Chudovo applies an AI-assisted development approach to barcode scanning projects, with the tools supporting work on scanning SDK integration, mobile application code, and 3rd party API integration under senior engineer review.
Real-World Scanning Performance
Chudovo engineers scanner applications for real retail environments where scanning conditions are anything but ideal.
Commerce-Aware Integration
Chudovo builds the scanner as part of the commerce workflow, with product data, pricing, inventory, cart, and payment connected through the retailer's actual systems.
Chudovo delivers the scan-and-go workflow as a combination of scanning, cart management, mobile payment, and checkout validation in one continuous experience. The steps below show how a working scan-and-go flow operates.
| Step | What Happens |
| 1. Store Entrance | Customer selects or enters a store in the app |
| 2. Load Configuration | App loads product and pricing configuration for the store |
| 3. Scan Barcode | Customer scans the barcode of the product |
| 4. Product Display | Shows product information, price, and relevant promotions |
| 5. Add to Cart | Product added to the mobile cart |
| 6. Mobile Payment | Customer pays via the app |
| 7. Create Checkout Code | App creates a checkout code or digital receipt |
| 8. Exit Validation | Purchase verified at departure (FastLane, staff check, or guarded exit) |
| 9. Retail System Sync | Transaction and inventory data sync with the retailer’s commerce, inventory, and analytics platforms |
The success of barcode reading technology depends largely on its performance in real retail conditions. In Chudovo’s Quality Assurance program, there is coverage of the environmental, hardware, and operational conditions relevant to the real-life deployment of the software — specifically, the low-light and packaging issues that generic mobile quality assurance programs do not cover
| Condition | What’s Validated |
| Lighting and packaging | Low light, glare, glossy or clear film packaging, curved or small product surfaces |
| Label condition and angle | Damaged, partial, off-angle, or upside-down labels, at distances from near-camera to arm’s length |
| Multiple and duplicate scans | Correct target selection with several barcodes in view; no duplicate entries in a session |
| Connectivity and load | Slow or intermittent Wi-Fi, catalogs with millions of SKUs, peak shopping loads |
| Payments and sessions | Graceful handling of declined payments and network errors, and battery life across long scanning sessions |
The choice between native and cross-platform development affects delivery speed, code maintenance, and scanner performance. Chudovo delivers both approaches — native iOS/Android when scanning performance and hardware integration are critical, and cross-platform (Flutter, React Native, .NET MAUI) when shared codebase and time-to-market matter more.
| Native Application | Cross-Platform Application |
| Maximum camera control | Shared codebase across platforms |
| Platform-specific optimization | Faster delivery for two platforms |
| Easier hardware-level integrations | Lower initial development effort |
| Best for complex scanning workflows | Suitable for standard scanning scenarios |
| Separate iOS and Android codebases | One primary application codebase |
| Higher long-term maintenance effort | Potential SDK and device limitations |
Barcode scanning projects range from single-store MVPs to enterprise platforms serving national retail chains. Chudovo scopes each project against the client’s stage and market position.
| MVP | Enterprise Solution |
| Camera-based barcode scanning | Camera and hardware scanner support |
| Basic product lookup | Real-time product, price, and stock data |
| Shopping cart | Full scan-and-go checkout |
| One e-commerce integration | POS, ERP, PIM, and WMS integrations |
| Online-only operation | Offline scanning and synchronization |
| Single store | Multi-store and multi-region support |
| Basic user account | Roles, permissions, and device management |
| Standard analytics | Centralized operational dashboards |
| One language | Localization and regional configurations |
| Standard barcode formats | GS1 standards and configurable format support |

Authentication to secure customers’ accounts
Role-based access control for staff and administrators
Data encryption in-transit and at-rest
Tokenized payments by certified third-party vendors
Safe API requests to backend services
Server-side cart validation to prevent price manipulations
Payment verification prior to the completion of the checkout process
Scanning fraud detection in case of any scanning abnormalities
Device and session management

GDPR and CCPA components in the course of data handling
Scope management with PCI DSS through integration with the payment providers certified by the same
Payment and PCI DSS Expertise
Chudovo integrates certified payment providers (CyberSource, Stripe, Adyen, SEPA) into scanner applications without expanding the client's PCI DSS scope. This is where most self-checkout projects run into cost and compliance issues.
Retail and Commerce Depth
Scanner apps live inside a commerce workflow. Chudovo brings the retail e-commerce experience — Magento, payment integration, PIM, POS, and inventory systems — that makes the scanner actually useful to the business.
Part of a Wider Retail and E-Commerce Practice
This work sits within Chudovo's broader retail and e-commerce practice, which covers custom e-commerce development, Magento work, marketplace platforms, and related domains.
Long-Term Support and Evolution
Scanner applications evolve with device generations, OS updates, and retail process changes. Chudovo supports scanning platforms through application maintenance and support services, including new integrations, feature expansion, and SDK migrations.
