Ultra High Radio Frequency Identification

May 26, 2009 07:00 PM

Cattle identification just got a lot faster, with Eriginate Corporation's development of eTattoo multiple ultra high frequency radio frequency identification (UHF RFID) ear tags. The new technology captures data from multiple animals simultaneously at faster speeds. Animal ear tags can be read from either the front or back of the animal, at distances of more than 25 ft. with a fixed reader or up to 15 ft. with a handheld reader. The tag's dangle design enables visual and electronic identification, so producers can include management and parentage information on the tag.

In a demonstration at the Holton, Kansas, Livestock Exchange in November 2008, in less than one hour, an antenna was installed on the left side of the sale ring. A group of 18 steers carrying eTattoo UHF RFID tags were run through the sale ring. All tags were read by the one antenna with 100% accuracy within 20 seconds.

Ultra high frequency tags differ from low frequency by having a longer read range, less interference and ability to read more data at a higher transfer rate. Price: $395 for 100 tags. www.etattootag.com.
