Harvest scanning suitcase
This portable scanning suitcase is designed for use directly in the field during harvesting to:
- Identify pickers, record harvest and pack time
- Collect and upload data in real-time to the cloud
- Enable efficient tracking and transparent reporting
- Boost accountability while reducing manual errors
The device provides real-time data collection and efficient reporting, reducing errors and improving overall efficiency of the harvesting process.

Used technologies
C++, Flutter, Java, Raspberry Pi, NFC, BLE, AWS
Development approach
To meet the demands of high-speed, field-ready QR scanning, we built the device around a Raspberry Pi 3 Model B with an Arducam Multi-Camera Adapter, enabling efficient scanning with minimal cameras and no reliance on OpenCV.
We added LED backlighting controlled via a transistor switch and developed a custom battery gauge and power PCB, ensuring up to 3 days of use on one charge. To reduce device size, we integrated mirrors into the camera system, while the outer case was designed for ergonomic field use.
The system uses multithreading for fast parallel scanning (up to 8 items) and sends data via BLE to a mobile app, with seamless cloud sync and OTA firmware updates.
Result
A fully functional prototype has been developed, meeting all key requirements for fast QR code scanning, reliable data capture, and seamless wireless communication. It’s designed to boost workforce efficiency and reduce operational costs.
