Low frequency technology is used for NAIT RFID tags (FDX and HDX tags). This is because it is currently the only proven and commercially available RFID technology for animal identification.
There is no proven range of ultra high frequency (UHF) animal tags available locally or internationally. However, the NAIT system is designed to accommodate UHF technology, and would be able to take UHF data in the future.
Any introduction of UHF technology for NAIT tags would follow a consultation period to assess costs and benefits.
