Qualcomm's new fingerprint sensor should be better than Touch ID.

Qualcomm has announced a new fingerprint reader that uses ultrasonic waves to verify your fingerprint in 3D, according to today's announcement. 

Unlike Touch ID, Qualcomm's "Snapdragon Sense ID" technology can read your fingerprint even if it's a little dirty or wet. It can even scan through "glass, aluminum, stainless steel, sapphire, and plastics," which means manufacturers should be able to integrate the fingerprint sensor into the phone's design, instead of having to make a discrete section made of different material just to support the sensor. 

For instance, the sensor could theoretically be built discretely into the bezel of a tablet.
