Your next phone could have a fingerprint reader on its screen

Apple Introduces Two New iPhone Models At Product Launch

Security technology firm Sonavation recently unveiled a novel means of embedding an ultrasonic fingerprint reader directly into a Gorilla Glass display. With it, mobile devices would no longer need a physical button, like the iPhone's Home button, to use as a fingerprint reader. Instead, they'd be able to press anywhere on the screen, finger grease smudges allowing. Apple has reportedly been working on a similar idea, although it doesn't seem likely we'd see a buttonless iPhone for at least another year.
