In-display fingerprint scanners have been around for years, but they aren’t all created equally. Most phones use a light-based sensor, but devices like the Samsung Galaxy S24 use an ultrasonic fingerprint scanner. These sensors aren’t widely available on smartphones, but that may be about to change.
Right now ultrasonic fingerprint scanners have only been manufactured by Qualcomm, and are quite expensive. However, Goodix and Vivo have unveiled a new “Ultrasonic fingerprint solution” on the Vivo X100 Ultra — specifically designed to help boost adoption of ultrasonic fingerprint scanners on more phones.
