Abstract

Identification apparatus for reading and identifying each of a plurality of transponders (such as identification ear tags for cattle) which are arranged to emit an identification signal. A plurality of antennae (1-14a; 61-69; 201-208) in the form of coils produce oscillating magnetic fields which induce currents in pick-up coils in the transponders and thereby provide the energy necessary to operate the transponders. The antennae also receive the identification signals. The antennae are driven by driving means (16; 200) for supplying an alternating current to the antennae (to create the oscillating field), wherein the driving means comprises a common driver connected to the antennae. There is also shown a feeding station or milking parlour having a number of stalls (150-153) in each of which a respective antenna is located so that the animal in each stall can be identified.
