Austin powers had one, and so did the six million dollar man - a biometric mouse... able to leap tall buildings with a single mighty squeek!

Go deeper my son, Use the force:
Curious as to how all this magical
authentication stuff works? Taking a look behind the sensor's screen we saw some pretty
high tech gear - for a mouse anyway's.
The clear sensor reflects an image of your fingerprint onto a small plastic
mirror which is directed at a optical reader. The finger print is never stored
as an image, but is transmitted as a 500 byte template file. The template gets
pushed through an algorithm which identifies the correct fingerprint and denies
any imposters. Biolink claims to have false acceptance rate of 1 in a billion,
and a false rejection rate of 2.1%.

Unlike a normal mouse the Umatch is packed to the gills with
circuitry and optics. The large sensor window is illuminated by to red
LED's during authentication. The red LED's allow the optical sensor to
read the finger print properly. |
 |
From this vantage point the three components of the authentication
system are evident. The fingerprint is generated on the large optical
window, reflected off a small plastic mirror and captured by the
integrated optical sensor. |
 |
The aperture of the optical sensor is rather small but the image is
captures is sufficient to enable the authentication algorithms to do
their work. |
