OVERVIEW
OVERVIEW
Checkout often fails in high-traffic retail—long queues, slow scans, and fragile self-checkout create loss and frustration, especially across large store networks. RadiusAI’s ShopAssist tackles this with real-time computer vision, recognizing items instantly to keep checkout fast, reliable, and effortless. This case study shows how a high-throughput computer vision system reduces checkout time and lowers the effort required from store staff and customers.

Camera Layer
This layer continuously captures and interprets items placed in the checkout zone,
enabling real-time detection and pricing.
Pilot Setup
Pilot Setup
The pilot setup included an overhead camera system, edge computer, and POS integration working together as a single unit.
Items placed under the camera were processed on the edge computer in real time, with outputs instantly sent to the POS system.
This ensured that recognized items automatically appeared on the cashier screen, enabling a fast and seamless checkout flow.

While the vision model could still recognize the type of food—for example, identifying something as pizza or custard—it could not reliably determine which exact item should be charged, especially at scale and during peak hours.
