After watching https://youtu.be/-fmBwINdsxQ I could imagine a world where we could have an implantable BLE beacon for room presence detection.
Would such a thing be possible?

Technical concerns aside… Battery, size, etc…
I feel like there would be some major security/privacy concerns:
Who else owns buildings that can track BLE beacons?
How do you prevent those with smart phones (check out BLE Radar app) from seeing if you are home?
How do we avoid it being controlled via a bluetooth vulnerability?
There are probably more, but I haven’t had coffee yet and I’m sure you get my point.
I’m sure the beacon could be turned on and off via a non-Bluetooth method, the first thing that comes to mind is NFC (maybe “if NDEF record == “on”: turn on BLE , else: turn off BLE”)…
But this would not solve all possible security/privacy issues in my mind.

Nothing is impossible however the ability to safely implant a battery at this point (or some form of capacitor) has not yet been reached.
One day a fusion reactor in my right lower leg may be possible and I will line up for it, ble tracking or not!

Oh boy I yearn for the day that a small solid state battery could last enough cycles, be powerful enough, and be small enough to reasonably fit into an implant without looking like someone with a peg leg (raspberry pi shoved in leg).
Closest thing we have at this point is a tritium battery and that only has a half life of 10 years and can’t be recharged to supplement it.
