The display fingerprint scanner, an in-display fingerprint sensor, is an advanced biometric authentication technology that enhances mobile security and convenience. Found in many modern smartphones, this feature allows users to unlock their devices, authenticate payments, and access secure apps by simply placing their finger on the screen. This guide will walk you through everything you need about getting and using display fingerprint sensors on your mobile device.
