Optical Sensor

Miniature Optical SensorThe miniature fingerprint sensor is a self-contained unit for capturing a fingerprint and communicating the digital image to a host processor via a USB interface. This small sensor is ideal for attaching to laptop computers, desktop PCs, and other PC equipment where fingerprint authentication is needed. Designed for ease of use it can read a fingerprint at any angle - even upside down. Its USB port capability makes it truly plug-and-play gaining you even easier access to Windows and the Net.It is capable of supporting security features such as the use of a challenge-response protocol to avoid playback attack when communicating with a remote server. Secure images produced by the sensor are only decrypted on a secure server. The low-cost compact fingerprint sensor incorporates precision optics, a LED light source, and a CMOS imager.Features of the Sensor High quality image Single, optimum image transmitted High speed USB interfaces Plug-n-Play Small footprint Encrypted image data Works well with dry, moist, or rough fingerprints Rejects fake fingerprints Cancels latent fingerprints Self-calibrating Rugged ESD resistant Proprietary optics Low cost compact design No external interfaces cords or power supplies required Compatible with Windows NT 4.0, Windows 2000, 98, and 95 OSR 2.1 (USB)Hardware Specification of the SensorSoftwareCompatibilityWindows 95 OSR 2.1(USB)/98/98SE/NT/ W2KAll PCs and Laptops with USB supportFingerprintMatching speed<= 0.3 second on Pentium 3Fingerprint angular variabilityReads at any angleFingerprint template data size128 bitsHardwareSize54 mm (w) x 65 mm (l) x 27 mm (h) (max)Fingerprint Imaging area13 mm x 18.1 mmImaging480 dpi (average x and y over image area)Image capture time<= 0.6 secondsInterface to hostUSB PortPower Management / Current consumptionSupply Voltage5V +/- .25V (supplied by USB interface)Supply Current200 mA (max) - While scanning fingerprint60 mA (typical) - Idle mode2.5 mA (max) - Suspend modeESD Susceptibility8KVTemperature Operating50 - 350 CTemperature Storage-100 - 600 CHumidity, operating20% - 80% non-condensingHumidity Storage20% - 90% non-condensingRetractable Touch SurfaceNo less than 15,000 in/out movementsUSB SpecificationsUSB 1.1 compliant: Full-speed, high power, bus-powered, bulk transfer, remote wakeupCableUSB 0.8m (31")Standards ComplianceFCC Class B, CE, VCCIApplicationsLaptop ComputersDesktop PCsNetwork PCsPC equipment requiring user authenticationPhysical access controlPoint-Of-Sale (POS) terminalsError.01% false accept rate for <4% false reject rate
