Half Duplex (HDX)

Half duplex (HDX) radio frequency identification (RFID) technology offers better resistance to interference from multiple tags in one area and metal items like head gates when reading identification tags. HDX technology provides optimum signal transmission for areas where read distance is important, such as automated reading systems, electronic sow feeders, walk-through readers and packing plants. When read distance is less important, full duplex (FDX) RFID technology can be used.
