Dual frequency identification device
First Claim
1. An identification system for animals, comprising:
- a structure for attaching the identification system to a body part of an animal;
a first radio frequency identification component having a first antenna operating at a first frequency;
a second radio frequency identification component having a second antenna operating at a second frequency, said second frequency being higher than said first frequency; and
a means for transmitting an identification code from both of the first and second antennas for allowing the identification code to be read by readers operating at different frequencies to identify the same animal.

Abstract
A dual frequency identification system for animals is contained within an ear tag structure adapted to be attached to an animal'"'"'s ear. The system includes a first radio frequency component having a first antenna that operates at a first frequency, and a second radio frequency component having a second antenna that operates at a second frequency higher than the first frequency. The radio frequency identification system is programmed to transmit the same identification code from both of the first and second antennas, whereby the tag can be interrogated by reader antennas operating at different frequencies to identify the same animal. Various constructions for the ear tag are disclosed in which the first and second frequency components are molded into the plastic parts of the ear tag.

14. A dual frequency identification system, comprising:
-
a first radio frequency identification component having a first antenna operating at a first frequency;
a second radio frequency identification component having a second antenna operating at a second frequency, said second frequency being at least an order of magnitude different from said first frequency; and
a programmable microchip associated with said first and second components for storing and transmitting an identification code from both of the first and second antennas so that the identification code can be read by readers operating at different frequencies.

15. A method of marking and identifying animals, comprising the steps of:
-
providing a tag having a radio frequency identification system with first and second antennas operating at different frequencies, and an identification code programmed into said system that can be transmitted from said first and second antennas;
attaching the tag to a body part of an animal; and
using a first reader to read the identification code transmitted from said first antenna. - View Dependent Claims (16, 17, 18, 19, 20)
