Congratulations on selecting Precise Biometrics’ Fingerprint Identification System! Using
your fingerprint for identification is an easy and secure way to prove your identity. Please
read this chapter before you install and use the system.
This chapter includes the following information:
• What’s new in Precise Logon 2.1
• The fingerprint reader
• The fingerprint identification process
• Why use fingerprint technology?
• The Precise 100 family
• Icons and conventions
What’s New
in Precise Logon 2.1
Three new main features are introduced with the Precise 100 Logon 2.1 software:
1. To enable biometric logon to a network, the installation of Precise 100 Logon
2.1 software is only needed on the client PCs. There is no need for any
additional software installation on the domain server.
2. The domain administrator has the possibility to remotely administrate user accounts
on the domain server by using the BioManager for Domains application, i.e.
administration can be done from any workstation in the network having the Precise
100 Logon 2.1 installed. The BioManager for Domains application is included in
the Precise 100 Logon 2.1 software.
3. The user has the possibility to remotely (i.e. from his own PC) enrol and re-enrol
fingerprints, changing primary logon finger etc. for his own user account, called
personal enrolment.
Introduction
Chapter 1 Introduction
Precise 100 A
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 Precise 100 A fingerprint reader
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!

Why Use Fingerprint
Technology?
In modern society, there is a vast need for secure identification, for instance when log-
ging into computer network. An unauthorised person who obtains access to computer
files constitutes a major risk to many companies. In order to prevent unauthorised access,
network users have previously identified themselves with a password entered together
with the username when logging into a network.
The disadvantages of passwords:
• Unreliable identification. An unauthorised person who knows your password
can easily access your user account.
• A complicated system. In order to increase security, users are regularly asked to
change their passwords. This makes it difficult to remember a password.
• Users forget their passwords, this increase the administration workload.
• Users write down their passwords on notes and store them close to their
applications. This can be a serious security hazard.
The advantages of fingerprint identification:
• Secure identification. By identifying yourself with your fingerprint, you use a
unique “key” to access your user account. All your fingerprints are unique –
no person has identical fingerprints.
• Simplicity. It is simple to use fingerprints for identification. You do not have
to worry about changing or memorising passwords anymore
– your fingerprint provides secure identification, year after year.
Simply put, with Precise 100 A, you are identified by who you are,
not by what you know!

Chapter 2
The installation consists of two parts. Start by following the instructions in the Preparing
Installation section. Then continue with the Installing the Fingerprint Identification Software
section.
NOTE: If you are using a Precise 100 A with parallel port connector, it is very important
that the parallel port of the PC is set to ECP mode before using the fingerprint reader.
Otherwise, the fingerprint reader will not function properly. See Setting the Parallel Port in
this chapter.
This chapter includes the following information:
• Minimum system requirements
• Preparing installation
• Setting the parallel port
• Connecting the fingerprint reader
• Installing the fingerprint identification software
• Attaching the fingerprint reader
NOTE: In order to log into your domain server account using your fingerprint:
• the Precise 100 A must be installed on your workstation
• your fingerprints must be registered on the domain server by a domain server
administrator using the Biomanager for Domains or by Personal Enrolment.
