Project at a Glance
The client required a friction-less in-store checkout experience that reduces queues, accelerates customer flow, and modernizes retail purchasing through mobile technology. The objective was to enable shoppers to independently scan products, complete payments within a mobile app, and exit stores efficiently while maintaining operational control and loss prevention.
We developed a complete contactless checkout ecosystem including Android and iOS customer applications alongside a dedicated store checker application used by exit staff to validate purchases through order barcode scanning.
The platform was tightly integrated with Odoo for inventory synchronization, order processing, and back-end retail management. This ensured real-time product availability, accurate stock tracking, and streamlined operational workflows across stores.
Solution & Implementation
We engineered a scalable mobile checkout infrastructure designed to integrate seamlessly into existing retail operations while maintaining security and speed.
Key implementation components included:
Customer Mobile Applications (Android & iOS):
- Real-time barcode scanning for product selection
- Dynamic cart management
- Secure in-app payments
- Order barcode generation for exit verification
- Real-time sync with inventory and store systems
Store Checker Application:
- Scan order barcodes at store exits
- Randomized item verification workflow
- Real-time order validation
- Fraud reduction and compliance support
The backend leveraged Odoo for inventory management, order processing, and operational control. AWS infrastructure provided scalable hosting and performance optimization, while Firebase supported real-time functionality and notifications.
React and TypeScript powered frontend experiences, with CodeIgniter managing supporting backend services. Mixpanel analytics were implemented to track user behavior, optimize flows, and improve conversion through data-driven insights.
The architecture prioritized speed, usability, and security to ensure a seamless retail checkout experience.
