As far as I know, the usual range on those implants is no more than ~30 cm, so I expect you might need a pretty powerful transmitter to find them across a room.

- rtkwe 6y agoThat's less a hard number and more a limit of how much power you're directing at it (with limits due to the inefficiency of RF energy transmission mostly) and how sensitive your receiver is. The passport RFID tags have been read from over 200 feet away for example.
