Standardisation

The development of standards is the responsibility of the technical committee of the
ISO. The ISO is the worldwide union of national standardisation institutions, such as
DIN (Germany) and ANSI (USA).
The description of standards in this chapter merely serves to aid our technical
understanding of the RFID applications dealt with in this topic and no attempt has been
made to describe the standards mentioned in their entirety. Furthermore, standards are
updated from time to time and are thus subject to change. When working with the
RFID applications in question the reader should not rely on the parameters specified
in this chapter. We recommend that copies of the original versions in question are
procured. The necessary addresses are listed in Section 14.2 at the end of this topic.

9.1 Animal Identification

ISO standards 11784, 11785 and 14223 deal with the identification of animals using
RFID systems.

• ISO 11784: 'Radio-frequency identification of animals — Code structure'

• ISO 11785: 'Radio-frequency identification of animals — Technical concept'

• ISO 14223: 'Radio-frequency identification of animals — Advanced transponders':

Part 1: Air interface
Part 2: Code and command structure
Part 3: Applications

The constructional form of the transponder used is not specified in the standards and
therefore the form can be designed to suit the animal in question. Small, sterile glass
transponders that can be injected into the fatty tissues of the animal are normally used
for the identification of cows, horses and sheep. Ear tags or collars are also possible.

9.1.1 ISO 11784 - Code structure

The identification code for animals comprises a total of 64 bits (8 bytes). Table 9.1
shows the significance of the individual bits.
