Description

Individual identification of cattle can be accomplished using various techniques such as ear tags, freeze brands, or tattoos. One of the newer methods in the cattle industry is Radio Frequency Identification (RFID) ear tags. Radio frequency identification is any electronic identification system comprising a transponder containing a microantenna that, when read at a specific radio frequency, emits a signal containing a unique electronic code. The three common physical forms of RFID transponders are ear tags, injectable transponders, and rumen boluses. All of these RFID transponders contain an integrated circuit, antenna, and some form of protection for these parts. At present, ear tags are the method primarily used by livestock producers.
