The Pentagon has a laser that can identify people from a distance–by their heartbeat

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

    Tipping that when this becomes standard we will have movie assassins and agents who can fake their way through scans by controlling their cardiac signature.

    It is interesting, the technology.

    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.

    Long-range detection
    A new device, developed for the Pentagon after US Special Forces requested it, can identify people without seeing their face: instead it detects their unique cardiac signature with an infrared laser. While it works at 200 meters (219 yards), longer distances could be possible with a better laser. “I don’t want to say you could do it from space,” says Steward Remaly, of the Pentagon’s Combatting Terrorism Technical Support Office, “but longer ranges should be possible.”

    Remaly, not fooling anyone, yes you are thinking space.

    I’m assuming that the technology could be easily defeated by anyone that knows it’s being used.

    Yep. The article says thick clothing thwarts it, which makes me think the movies will be sure to have the actors bare-chested or at least in a thin shirt when they do it, or possibly bullet proof vests and floor-length trenchcoats and screw being accurate.
