The Ultrasonic Fingerprint scanner is a revolutionary new biometric authentication feature that debuted on the Galaxy S10 series phones. It's an in-display fingerprint sensor fused into the Infinity-O Display, providing invisible yet vault-like security that keeps your data safe. Also known as simply Ultrasonic Fingerprint, when you place your finger or thumb on the screen, it sends ultrasonic pules to detect the 3D ridges and valleys of your unique fingerprint to quickly and accurately recognize you.
Setting up the Ultrasonic Fingerprint on the Galaxy S10 series is simple. Go to Settings, then Biometrics and Security. Find Fingerprint and follow the steps to set up your Ultrasonic Fingerprint.
*Ultrasonic Fingerprint is available on Galaxy S10, S10+, and S10 5G. Galaxy S10e has a Fingerprint Scanner located on the power button.
