Phones use one of three different technologies to read your fingerprint: optical, capacitive or ultrasonic. An optical fingerprint reader is the oldest of the three. It uses a specialised miniature camera to take a picture of your finger, often backlit with little LEDs or the phone's screen.
Which type of fingerprint sensor is best?
The third type of fingerprint scanner is one that isn't found on a number of devices, but is the most advanced and also much more secure than optical sensors. Ultrasonic sensors are also often seen below displays in phones like the iQOO 9 Pro.
Which type of fingerprint sensor is best in Mobile?
The in-display fingerprint scanner on the Galaxy A53 is much more precise as well as faster than the one on its predecessor, so you'll be able to unlock the device without an issue.
