Android and Windows to get 'kill switch'

[BC_Programmer]

Best anti-theft is to never let you iPhone or Smartphone out of sight.

Well I've never had a smartphone stolen from me. The key to success in my case is to not own one.

Pass on the word. We'll beat these thieves!

Maybe  something like a auricular implant. Part of the phone to be inside the head of the owner. 

Very bad idea - http://news.bbc.co.uk/2/hi/asia-pacific/4396831.stm

From the above link:

The attackers forced Mr Kumaran to put his finger on the security panel to start the vehicle, bundled him into the back seat and drove off.

But having stripped the car, the thieves became frustrated when they wanted to restart it. They found they again could not bypass the immobiliser, which needs the owner's fingerprint to disarm it.

They stripped Mr Kumaran naked and left him by the side of the road - but not before cutting off the end of his index finger with a machete.

In  that case a kill switch ......
