If all you need is presence detection then a motion sensor would be vastly more efficient.

If you actually need identity detection, then maybe, but you’ll still have to have a camera or detailed access logs to associate the interference signature with a known entity and at that point you may as well just put an RFID reader under the bowl you throw your keys into or use facial or gait detection.
