The Jetson prototype can pick up on a unique cardiac
signature from 200 meters away, even through clothes.

Everyone’s heart is different. Like the iris or fingerprint, our unique
cardiac signature can be used as a way to tell us apart. Crucially, it can be
done from a distance.
It’s that last point that has intrigued US Special Forces. Other long-range
biometric techniques include gait analysis, which identifies someone by the
way he or she walks. This method was supposedly used to identify an
infamous ISIS terrorist before a drone strike. But gaits, like faces, are not
necessarily distinctive. An individual’s cardiac signature is unique, though,
and unlike faces or gait, it remains constant and cannot be altered or
disguised.
