The Pentagon Can ID Your Heartbeat Using Laser Beams | Popular Mechanics

The Pentagon has developed a new means of identifying people in conflict zones: laser beams.

The Jetson prototype, developed for U.S. special forces, bounces a laser beam off a person to read their unique heartbeat signature, IDing them in seconds. The system is 95 percent accurate and can be used at distances of at least 200 meters, making them useful at locations such as military checkpoints (pictured above) and elsewhere.
