Once upon a time...
A long time ago, when men were men and they hacked into satellite TV systems, there was a certain bit of hardware often jammed into the Smartcard slot. A long gangly PCB with wires and things hanging out. As it happens, the circuit emitted spurious signals on the emergency beacon frequency of 121.5 MHz.
Such signals will eventually attract a large helicopter. Such search and rescue helicopters are obviously equipped with precisely the sort of highly sensitive beacon receivers and DF/Homing equipment needed to place the noisy thing hovering directly over one's house at about 11 PM.
Just a bit of history.
