The Allflex USDA 840 FDX EID button tags have a unique design that provides the ultimate in usability, security and retention. This single use tag features a hard plastic Tamperproof cap. Transponder numbers are laser marked in a circular format on the edge of the tag.
Full Duplex Technology (FDX) is utilized with the USDA 840 FDX EID tag. FDX is a design principle whereby the return signal initiates as soon as the beginning of the interrogation signal is received and the smoothing capacitor in the transponder has been charged. The return signal is received repetitively and without interruption for as long as a continuous interrogation signal is maintained. A FDX Transponder doesn't have to store energy to be able to return its entire data signal.

Also available are a Lightweight USDA 840 tag in Yellow which work well for Sheep & Goats or smaller Pigs.
Larger quantities of these tags are special order. Please allow approx. 2 weeks for delivery.
