Miniature UHF RFID Tags

Xerafy’s XS Series of UHF RFID tags are specifically designed to be the smallest and most rugged RFID-on-metal or Embed-in-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 XS tags to small metallic assets that have been too challenging to track in the past. The durable XS Series can survive temperatures of up to 150°C and other harsh elements such as high impact and caustic chemicals. Ideal for tracking tools or medical instruments.


  • High performance RFID-on metal tags
  • Passive UHF EPC Class 1 Gen 2
