The silicon sensor consists of 40.000 distance measuring sensors using an improved capacitive principle. The sensor can be programmed in such a way that it is insensitive to common problems, such as a ghost-image due to remaining sweat. This principle has been recently filed at the Swedish Patent Office. The chip is fabricated by Mietec-Alcatel. The system has been developed in cooperation with Nordic VLSI for Fingerprint Cards AB. One of the intended application fields is the telecom market for securing portable phones. For more marketing information contact Fingerprint Cards AB.
