I’m leaning towards RFID tags too, but I wonder if there are any farms using those 802.11 wireless radios for tracking instead.

I’m a bit confused; I feel like I’ve seen other options like photodiode sensors in different contexts, but I think RFID is the right answer here.

I think RFID tags are the most common for tracking livestock, but I’m not entirely sure if there are other methods used as well.
