The Zebra WT6400 is a wrist- or hip-mounted wearable computer built for hands-free scanning in warehouses and distribution centers — workers wear the terminal while a separate ring or finger scanner does the actual barcode reading, keeping both hands free for picking and packing. This configuration has a touch display with a physical keypad, a 3500mAh standard battery, 6GB of RAM with 64GB of flash storage, and a 13MP side-mounted camera for capturing proof-of-delivery or damage photos on the job. It runs Zebra's rugged Android-based mobile platform designed for industrial use (drop resistance, sealed housing), aimed squarely at logistics, fulfilment and manufacturing environments rather than general business use.
