Fingerprint - Capacitive Sensors
The capacitive method is one of the most popular methods. Like the other scanners the capactive fingerprint scanner generates an image of the ridges and valleys that make up a fingerprint. The capactive sensor uses capacitors with electrical current for measuring the fingerprint. A capactive sensor is made up of an array of tiny cells. Each cell includes two conductor plates, covered with an insulating layer.

The main advantage of capactive sensors is that they require a real fingerprint. Capactive sensors have problems with wet and dry fingers. With wet fingers the users sometimes get black images, whilst dry fingers make the image pale.
Leading manufacturers of capacitive sensors are Infineon, Veridicom, Sony and ST Microelectronics.
