A system for reading tags for livestock, the system comprising

• a plurality of animal tags,
• at least one reader installed at a fixed position;
• the plurality of animal tags are active tags,
• the at least one reader is configured to receive a radio signal emitted by the plurality of animal tags, the plurality of animal tags are configured to emit the radio signal at predetermined intervals,
• the system further comprises a processor configured to:
• read the unique identifier from the radio signal,
• determine an angle of arrival of the radio signal,
• determine a position of the plurality of animal tags based on the angle of arrival of the radio signal,
• wherein
• said plurality of animal tags comprise a beaconing interface programmed to emit said radio signal, wherein the beaconing interface is programmed to stay in a listening mode by default and to wake up when a wake-up signal from the reader is received,
• the wake-up signal from the reader has a predetermined coverage so as the plurality of animal tags wake up only when placed within the predetermined coverage, wherein the radio signal at predetermined intervals is emitted by the beaconing interface if the wake-up signal is received,
• the processor is further configured to:
• determine that one animal tag having the determined position has to be considered for further processing, based on said determined position.
