capacitance scanner

A type of fingerprint scanner that requires a real fingerprint as opposed to a black and white image that would be used on an optical scanner. This type of scanner senses the fingerprint using electrical current instead of light, as optical scanners do and are said to me more secure as it is more difficult to forge a fingerprint on a capacitive scanner.
