Abstract: A label is described for attachment to an animal. The label includes a transmitting and receiving device having an electric oscillator circuit that, upon closure of the oscillator circuit, generates a periodic electric oscillator signal with an oscillation period for transmitting an electromagnetic beacon signal with the transmitting and receiving device. The label is configured for closing the electric oscillator circuit during a predetermined transmission duration, and is further configured for opening the electric oscillator circuit upon elapse of the predetermined transmission duration, wherein the predetermined transmission duration corresponds to at least one and at least a whole number of oscillation periods of the electric oscillator signal.
