Read tags of animals quickly and reliably


  • Electronic identification technology (RFID) based on Ultra high frequency radio waves
  • Very interesting properties for mass reading
  • Simultaneous multiple readings
  • Reading distance up to several meters
  • Recognition: individual and group


The UHF (Ultra High Frequency) RFID (Radio Frequency IDentification) identification tag linked with a suitable antenna allows multiple and simultaneous readings of animals, at distances of several meters, unlike official tags (at low frequency). This device makes possible to read the identification numbers on lots of moving animals and adapts to individual proximity reading for the analysis of attendance at points of interest (watering trough, trough, for example).

The UHF RFID electronic tag, positioned on the ear, is detected by the antenna connected to a fixed or portable reader that can be controlled on a smartphone. The reading distance adapts according to the adjustment of the power of the reader (few cm to 2.5m). The information is available on a server or can be read directly using a smartphone application.

How to implement:

UHF RFID identification tags must be fitted on the entire herd when lambs or kids are born.

The electronic tag must be placed on the left ear of the animal. The breeder must also be equipped with automatic readers compatible with these UHF RFID identification tag.

Expected benefits:

  • Time saving: less targeted user gesture, possibility of adjusting the reading distance by modulating the power.
  • Traceability: functional and comparable to low frequency, reading distance slightly greater at low frequency
  • Interoperability: compatibility and links with many systems (milking robots, DAC, DAL, scales)

Prerequisites and/or limits:

  • Possible loss of tags
  • Impossible to read through an animal
