SecuGen FDU02
Theory of Operation
The USB host initiates the communication with the FDU02 using operation commands.
Fingerprint data are then captured by the CMOS sensor at a total image size of 400 x 300 with
8-bit gray level. The image frame transfer speed is around 800 bytes/ms. It takes about 400
milliseconds to send one complete frame of image data over USB protocols. FDU02 uses the
SecuGen Fingerprint Optic Reader. For developers, the SecuGen Software Development Kit
(SDK) Collection provides the tools necessary to integrate this module into their own software
applications using SecuGen’s powerful Fingerprint Recognition Algorithm.
