It's one of the worst-kept secrets in the phone industry: Samsung is hoping to eventually sell you a phone with a fingerprint sensor that lives underneath the screen.
But how? Well, a pair of reports out of China and Korea suggest that sucker might be ultrasonic -- firing high-frequency acoustic waves through the glass that capture your fingerprint without fear of being defeated by dirt or grease.
Might be fun to hack the sensor to do other things.

Nah you're thinking about it all wrong. Use the sensor to send them an ultrasonic image of your butt.
