The Zebra WT5400 is a wrist-worn ("wearable") mobile computer with a touch display, built for hands-free barcode scanning in warehouses and distribution centres -- worn on the forearm and paired with a separate ring or gun-style scanner, freeing up both hands for picking and packing rather than holding a handheld scanner. This configuration has an extended 5000mAh battery for longer shifts, 6GB RAM/64GB flash storage, a USB-C connector for charging and data, no camera, and is the "Rest of World" regional variant (as opposed to a US- or region-specific radio/regulatory version). Aimed squarely at logistics and fulfilment operations running high-volume, repetitive scanning workflows rather than general-purpose mobile computing.
