Capacitive fingerprint scanners generate an image of the ridges and valleys that make up a fingerprint. But instead of sensing the print using light, the capacitors use electrical current.
The sensor is made up of one or more semiconductor chips containing an array of tiny cells. Each cell includes two conductor plates, covered with an insulating layer. The cells are tiny smaller than the width of one ridge on a finger.
The sensor is connected to an integrator, an electrical circuit built around an inverting operational amplifier. The inverting amplifier is a complex semiconductor device, made up of a number of transistors, resistors, and capacitors. 
The main advantage of a capacitive scanner is that it requires a real fingerprint-type shape, rather than the pattern of light and dark that makes up the visual impression of a fingerprint. This makes the system harder to trick. Additionally, since they use a semiconductor chip rather than a CCD unit, capacitive scanners tend to be more compact than optical devices.
Finger scanning, also called fingerprint scanning, refers to any of several different technologies for electronically obtaining and storing human fingerprints. The digital image obtained by such scanning is called a finger image. Other methods of finger scanning besides the capacitive method include optical scanning, thermal (heat) sensing, and pressure sensing.
