Welcome to NAIT

Types of NAIT tags

NAIT approved tags use RFID technology. Each tag has a globally unique 15 digit number, which can be read by RFID scanners. The NAIT system keeps a record of individual tags and information about the animals that have been tagged and registered. Remember to get the right colour tags for your animals:

  • White tags are for cattle. They must also have a white back (male) portion.
  • Orange tags are for deer. The back (male) portion can be any colour except white.

HDX or FDX tags?

NAIT tags come in two broad types - HDX and FDX. This relates to the way they operate when they are scanned by an RFID reader.

HDX and FDX tags differ in both price and functionality. You can choose either option for your NAIT approved tags.

HDX (half duplex)

HDX tags are higher performing and have a longer read range. They also have protection from outside interference. 

  • Some on-farm automation systems (e.g. Protrack) will only work with HDX tags
  • HDX tags are a popular choice for dairy farmers
  • Some older cattle crushes with a lot of metal noise are better suited to HDX

FDX (full duplex)

FDX tags have a shorter read range and no protection from outside interference.

  • FDX tags are suited to most sheep and beef environments
  • FDX tags meet the minimum requirements for NAIT compliance. 

Both HDX or FDX tags will have better performance if they are read with a scanner that is tuned to that type of tag.

Birth tags

Birth tags should be used for all newborn animals. They are printed with:

  • a herd number (NAIT number from 1 July 2015) or dairy participant code
  • the year (optional if not ordering through LIC or CRV), and
  • the animal's sequence number.

Birth tags can also be purchased with a matching visual panel tag. This is know as a birth set. Having a matching panel tag makes it easier to see the animal's management ID number for use on farm. This is useful if an animal loses its RFID tag and you have to update the NAIT system, or to identify animals when you are selling or moving them off farm.

Replacement tags

Replacement tags should only be used for animals that lose their existing NAIT RFID tag. They will have a similar print format to current traka tags:

  • a NAIT number or dairy participant code, and
  • the tag's RFID number.

Old tag types

Traka and management RFID tags are no longer sold. These tags can still be used as long as they were issued before July 2015.

Traka tags are printed with:

  • a herd number or dairy participant code, and
  • the tag's RFID number.

Management RFID tags are printed with:

  • the tag's RFID number
  • a dairy participant code, and
  • the animal's sequence number.
