Biometric
A biometric is a measurable, unique, physical characteristic. For example, the pattern on
your retinas and your fingerprints are biometrics.
ECP/Enhanced Capabilities Port
The Precise 100 A PAR and Precise 100 SC PAR readers communicates with the comput-
er via the computer’s parallel port. To make the fingerprint reader and computer communi-
cate properly via the parallel port, the parallel port must be set to a mode called ECP –
Enhanced Capabilities Port. Most new computers are set to ECP by default, but not all.
See the Installation chapter for details. This does apply for USB readers.
Enrolment
The process of registering your fingerprints is sometimes referred to as enrolment, as you
are enrolled into the system as a biometric user. See Registration for more details.
Finger Pad
The finger pad is the part of your finger containing the fingerprint. If you take a closer
look on your finger pad, you will find that most of the information in the fingerprint comes
from the middle of the finger pad. That is the part, which should be placed in the middle
of the sensor when you register or log on.
Fingerprint Reader
The fingerprint reader is used for two things: to read a finger placed on the sensor, and to
read and store information on a smart card. 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. If you have a personal smart card, insert it into the slot
before placing your finger pad on the sensor.
