The Y-TEX RFID 840 FDX button-style tags employ full-duplex (simultaneous signal back and forth between reader & tag) technology and weigh 6.42 grams.
These tags are approved for use as USDA ADT (Animal Disease Traceability) Official ID tags.
These tags are encapsulated in a soft polyurethane material and are intended to be used as livestock ID where exposure to various weather environments, liquids and temperature changes are significant. The new RFID button-style tags have increased read distance and performance in noisy environments - including those with a high amount of metal and electrical interference.
Neither direct contact nor line of sight is required for accurate RFID reading. Tags can be read quickly and accurately in milliseconds through a variety of nonmetallic materials such as dirt, paint and cement.
