What is capacitive fingerprint sensor?

What is the difference between optical and ultrasonic fingerprint sensor?
The optical sensor captures the fingerprint’s 2D image during setup and stores the data on the device. …
The image is then compared to the recorded image
. On the other hand, as the name suggests, the ultrasonic fingerprint scanner uses very high-frequency sound. The sound waves are used to map users’ fingerprint data.
What is an optical fingerprint scanner?
The way an optical scanner works is by
shining a bright light over your fingerprint and taking
a digital photo. The light-sensitive microchip makes the digital image by looking at the ridges and valleys of the fingerprint, turning them into 1’s and 0’s, and creates the user’s own personal code.

The best system was accurate
98.6 percent of the time on single-finger tests
, 99.6 percent of the time on two-finger tests, and 99.9 percent of the time for tests involving four or more fingers. These accuracies were obtained for a false positive rate of 0.01 percent.”
IS fingerprint safer than password?
