Frequently Asked Questions (FAQs)

What’s RFID?
RFID stands for Radio Frequency Identification, and it is also referred to as Electronic Identification EID.
An RFID ear tag carries a unique electronic identification number and allows animals to be electronically recognised and data stored automatically about each animal. 
On farm, an RFID system consists of:
  • Tags: house the transponder that hold and sends the identification information
  • Readers: energises the transponder of the tag and receives identification information
  • Data Collectors: stores the identification information
  • Data Processors: uses the information and provides outputs of data.
RFID tags are available in two technologies, Half Duplex (HDX) and Full Duplex (FXD)
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
In New Zealand:

  • 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
  • HDX is approx. 40% more expensive than FDX

FDX (Full Duplex)

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

  • FDX is ideally suited to most sheep and beef environments
  • FDX is also suited to most deer shed environments
  • FDX is a less expensive option
When Should I use RFID HDX tags?
  • HDX RFID tags are suited for use with RFID wands
  • HDX performs with most types of panel readers
  • In sheep weigh crates
  • In automated dairy or beef systems
  • When using a panel reader for cattle, sheep & deer
  • In a noisy and high metal environment like dairy sheds

When Should I use RFID FDX tags?
  • FDX RFID tags are suited for use with RFID wands.
  • FDX performance varies with different types of panel readers; therefore it is important to get expert advice as to which reader to install. 
  • Non-noisy environments such as wooden deer yards
  • Narrow races with a panel reader like a sheep race
  • Sheep weigh crates 

Birth ID tag versus Traka tag



The difference between a Birth ID tag and a Replacement tag (Traka) is the information printed on the tag. Both types of tags are offered in the HDX and FDX technologies. The cost for the tags is the same when comparing the same technology.

A Birth ID tag is printed with:

  • AHB or Minda logo
  • Animal number
  • Year of birth (optional)
  • AHB herd number or LIC participant code

A Traka tag is printed with:

  • AHB or or Minda logo
  • 16-digit RFID number where the first digits are related to the manufacturer code, for Zee Tags, 942 is the manufacturer code
  • AHB herd number or LIC participant code                                                                                                       
When do I use a Birth ID tag or a Traka tag?

Birth ID tags are ideal for tagging new born animals to make them compliant with the NAIT scheme.

Traka tags can be used to make existing animals NAIT compliant before their first off-farm movement. They can also be used as a replacement NAIT tag if the original tag is lost.

For cattle, both portions of the tag, female and male must be white, and for deer, the female portion of the tag must be orange, and the male tag can be any colour but white.

What type of RFID tag is compatible with my Dairy Shed System?
If you have one of the following Dairy Shed Systems, Zee Tags recommends the use of the following RFID tags:

  • Gea: Both FDX and HDX tags have a good performance
  • MilkHub: Both FDX and HDX tags have a good performance
  • Protrack: RFID HDX only
  • Jantec: RFID HDX only
  • Pegasus: RFID HDX only
  • Delaval: RFID HDX only
Do I still require secondary tags to send animals to slaughter, to be sold or to be moved off-farm?

No, the secondary tag is no longer required under the NAIT regulations, but most farmers still use them for management purposes.

When do the NAIT regulations for Deer come into force?

1st March 2013.
