The Samsung Galaxy S10 is slated to become the first ever smart phone to incorporate an in-screen ultrasonic fingerprint scanner. This technology is sure to be the “wave of the future” because this type of sensor takes up no room on the phone thus, allowing the phone screen to be larger overall. The 3D Sonic Sensor uses sound waves to help you unlock your phone. The phone emits an ultrasonic sound that bounces back off of your finger and tells the phone whether or not the finger is registered to unlock that phone. This is different than current fingerprint unlock technologies that take a static picture of your finger and then compare it to a key by analyzing the different lines in the picture in order to determine if the person holding the phone is the owner. In addition, this new 3D Sonic Sensor is safer to use than traditional fingerprint unlock technologies. For previous iterations of fingerprint unlock systems, hackers have been able to use photos of an individuals fingers in order to unlock their phone. With an ultrasonic sensor, that will no longer be possible. The sensor actually can get an imprint as deep as the pores in the fingerprint which would be impeccably hard to duplicate. To summarize, Android users have something to be very excited about. They will no longer have a sensor that takes up room on their screens and their phone and personal information will be better protected from malicious hackers.
