Fingerprint Reader
The fingerprint reader is used to read a finger placed on the sensor. The sensor measures
the capacitance of 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 reader is used both to enrol a fingerprint to store it in a database, and to
verify a fingerprint during logon.

Fingerprint Template
A fingerprint template is a data file containing information about the fingerprint. The fin-
gerprint template is a set of characteristics which are unique for one specific fingerprint
and is not an image of your fingerprint. Your actual fingerprints cannot be recreated using
the data from the fingerprint template.
Fingerprints
Your fingerprint can be described as a pattern of lines or ridges with valleys in between.
The lines form specific patterns that are observable to the naked eye. Loops, arches and
whirls are examples of patterns found in a fingerprint.
