Allflex USDA 840 HDX (Half Duplex) Ultra EID Tags, 50 ct

Allflex USDA 840 HDX Ultra EID Tags offer premium performance and durability for livestock identification. These tamperproof, ISO-compliant ear tags use advanced Half Duplex (HDX) technology to deliver superior signal strength and the longest possible read range - ideal for walk-through readers and packing plants.

These HDX EID tags are compliant with Federal Animal Disease Traceability regulations and help verify that animals were born in the USA. Each tag includes a unique 15-digit ID number linked to your Premise ID, stored in the NAIS database.

HDX vs. FDX Technology:

HDX (Half Duplex) and FDX (Full Duplex) tags differ in how they transmit data. HDX tags send data only after fully receiving power, resulting in a longer read range and better signal reliability - ideal for automated systems and environments with signal interference. FDX tags transmit data continuously and offer faster reads at shorter distances, making them more suitable for handheld readers or up-close scanning. While FDX tags are often used for feeder cattle, HDX tags are preferred for operations requiring precise, consistent reads from greater distances and potential interference.
