  Xerafy’s X II Series of UHF RFID tags are specifically designed to be the smallest and most rugged RFID-on-metal tags in the world, for industrial markets where critical and potentially hazardous situations require reliable identification of assets. Xerafy’s patented RF antenna design provides an unrivaled performance-to-size ratio, reducing tag size and allowing customers to attach X II tags to small metallic assets that have been too challenging to track in the past. The durable X II Series can survive temperatures of up to 482°F (250°C) and other harsh elements such as high impact and caustic chemicals. Features
