As allways my intervention is to change the focus of the thread. Because we are security consultants, we have to now that this things realy works, and many entusiastic boys can try into ower enterprices or even specialiced industrial spy or terrorist can use this method. So the thru point here is how to keep them out when they try to do some penetration with this method. The method expoused are good, also the point of temperature. lest find other ways to keep the good intention of the thread, and suges ways to make the perimetral security bether. I cann sugest a wheigt detector, to complete the finger print scanner with temperature mesurement capabilities.
