The Fingerprint Reader
The fingerprint reader includes a sensor for reading fingerprints. When you place your
finger on the fingerprint reader, the part of the finger that touches the sensor is read. The
sensor measures the capacitance in the finger pad, which reveals the pattern of the
fingerprint. Thus, a paper copy with a picture of a fingerprint can not grant access to the
system.

The Fingerprint Identification Process
When logging into a system, your fingerprint is compared to a fingerprint template, i.e. a
data file containing information about the fingerprint, stored on a hard disk.
The fingerprint template is a set of characteristics which are unique for one specific finger-
print and not an image of your fingerprint. Your actual fingerprints cannot be recreated
using the data from the fingerprint template.
If your fingerprint matches the fingerprint template, the system will grant you access. If the
match is not successful, the system will deny access. It takes less than one second for the
system to compare a read fingerprint with the information in the database. All information
sent between the fingerprint reader and computer is encrypted for maximum security.
At logon, you simply enter your username and place your finger on the fingerprint reader
to log into the system!
