What is the difference between RFID HDX and FDX tags?

HDX (Half Duplex)

HDX talks to the reader like a 2 way radio, the reader sends out a signal then the tag replies

Several dairy sheds systems are HDX only which makes this type of technology the most popular choice within dairy farmers.

Some older cattle crushes with a lot of metal noise are better suited to HDX


FDX (Full Duplex)

FDX is like a phone conversation; as soon as the tag receives the reader signal both tag and reader talk simultaneously.

FDX is ideally suited to most sheep and beef environments
FDX is also suited to most deer shed environments
