PROJECT TOPICCommercial Services & Consumer Systems
Smart Supermarket Shopping Cart
A connected retail shopping concept examining battery-powered embedded tablets, basket load-cell arrays, and multi-angle optical barcode scanners to allow shoppers to scan items as they shop and bypass checkout lanes.
In-Aisle Frictionless Retail Scanning
- ✓Enables shoppers to bag groceries directly as they pick them from supermarket shelves.
- ✓Cross-verifies scanned barcodes against real-time cart basket weight increases.
- ✓Recharges automatically through magnetic conductive contacts in the cart return corral.
The Engineering Challenge
Problem / Objective
Shoppers spend long periods waiting in checkout lines, while retail shrinkage occurs when self-bagged items go unscanned.
