The Zebra T5400 (Zebra's WT5400 wearable computer) is a wrist- or arm-worn rugged terminal built for hands-free barcode scanning and data capture in warehouses, distribution centres and logistics operations where a worker needs both hands free while still carrying a connected computer. This configuration has a touch display, the standard 3,500mAh battery (an extended 5,000mAh option also exists in the range for longer shifts), 6GB of RAM and 64GB of flash storage, and connects via USB-C rather than a proprietary cradle-only connector. It's specified with no camera, keeping the unit focused on core wearable scanning/data-entry duty rather than photo capture. As a genuine rugged wearable in Zebra's enterprise line, it typically runs Android and carries an industrial ingress-protection rating, though exact OS version and IP rating for this specific unit should be confirmed against Zebra's datasheet. It's typically paired with a separate ring scanner or hip-holster component to complete a full wearable data-capture setup.
