| Miniature Optical Sensor |
The 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.
