I – CONSIDERATIONS
Environmental Considerations
Do not install or operate the F707/708 where there is very strong light.
Intense light will adversely impact the fingerprint sensor’s ability to
accurately read fingerprints. The F707/708 is primarily designed for
indoor use. If it must be installed outdoors, protect it with an all-weather
protective covering such as outdoor enclosures manufactured by STI USA
(www.sti-usa.com).
The F707/708 operating temperature range is 0° to 40° C (32° to 105° F).
Do not operate the F707/708 in very hot environments. Keep the
F707/708 away from direct heat sources and provide adequate ventilation
to prevent the F707/708 from overheating.

51
II - Abbreviated Operating Procedures
Step 1
Install the F707/708 and power it up.
Step 2
Enroll users by registering his/her fingerprints or passwords. If the
F707/708 is operating in stand-alone mode (where no 3rd party access
control panel exists), assign users’ security privileges directly on the
F707/708.
If using the F707/708 with a 3rd party Wiegand access control panel, users’
security privileges will be maintained by the access control panel and
NOT the F707/708.
Step 3
After enrolling user(s), verify his/her enrolled fingerprint(s) or password is
recognized by the F707/708.
Step 4:
Configure the F707/708 communication settings. Then download the
users’ newly enrolled fingerprints from the F707/708 onto a computer.
Data can be transmitted via TCP/IP or by a cross-over cable and laptop
computer
Note;
We always recommend backing up the fingerprint templates on to a
computer or removable media. If the F707/708 ever fails or is
vandalized, having a “backup” eliminates the need of having to
re-enroll all your users all over again. Having a “template backup”
can potentially save you a lot of time.
Step 5
Verify the F707/708 displays the correct day and time

III – Introduction to Fingerprint Recognition
Technology
Prior to operating the F707/708 it is essential to first understand how
fingerprint recognition technology works.
Adding and verifying fingerprints is the core function of the
F707/708. Once a thorough understanding of fingerprint
recognition technology is obtained, you’ll find your experience with
the F707/708 to be very productive and rewarding.
How fingerprint recognition technology
works
When the user places his/her finger on a Fingerprint Recognition Device
(i.e. F707/708) for the first time, the fingerprint is scanned and converted
into a computer-generated “biometric template”. The templates can only
be recognized by each respective biometric manufacturers’ devices. Also
note that these “templates” are NOT actual fingerprint images. “Real”
fingerprint images cannot be re-generated from these templates.
All fingerprints contain a number of unique physical characteristics called
minutiae. Minutia include certain visible aspects of fingerprints such as
ridges, ridge endings, and bifurcation (forking) of ridges. Most of the
minutiae are found in the core points of fingerprints, and the core points
themselves are found near the center of the fingerprint on the fleshy pad of
the finger.

53
Figure A-1 shows the positions of core points within fingerprints. The
core points are represented by the red dots in the figure below (note: if this
manual is printed in black and white you’ll only see a thick dot near the
upper ridges in the figure below):
Figure A-1
A core point is defined as the topmost point on the innermost upward
recurring ridge line.
A user is considered “enrolled” in the F707/708 after his/her fingerprint(s)
or password has been successfully registered in the database of the
F707/708.
During the enrollment process, when the user places his/her finger(s) on
the F707/708 fingerprint sensor, the F707/708 takes a picture of that user’s
finger’s key minutiae points. The F707/708 then uses its proprietary
mathematical algorithm and converts that picture into a unique
mathematical template which is comparable to a 60-digit password. This
unique template is then encrypted and stored in the F707/708 database.
IMPORTANT NOTE
Privacy issues should never become a concern when using the F707/708,
since NO REAL IMAGE OF A USER’S FINGERPRINT IS ACTUALLY STORED.
Instead, ONLY the minutiae-based templates are actually stored.
Each time a user’s fingerprint is scanned, the F707/708 searches its
database for a matching fingerprint. If the F707/708 finds a user’s
matching fingerprint, then his/her “attendance/door access” is recorded in
the F707/708 “audit log” and will be noted in subsequent reports.

54
Getting Good Fingerprint Images
The quality of fingerprint images is relative to the number of minutiae
points captured by the F707/708’s sensor. Fingerprint images not
possessing an adequate number of minutiae points may be unreadable.
For those users whose fingerprint images lack sufficient minutia points
and cannot be read by the sensor, it’s advised to issue those few users a
secret password, instead. You may also consider purchasing an F707/708
with an integrated card reader, if you prefer not assigning passwords.
Figure A-2 shows poor-quality fingerprints, characterized by smudged,
faded or otherwise distorted areas on the fingerprint. These conditions can
be caused by excessive dryness or wetness, excessive or insufficient
pressure, or scarring of the skin at the fingertip.
Figure A-2
The F707/708 fingerprint matching algorithm is often capable of
extracting the correct minutiae even without the benefit of a perfect print.
However, the positioning of the finger and the relative moisture and
pressure of the fingerprint when it is placed on the sensor are important
contributing factors in achieving a good consistent fingerprint match.

55
Correcting wet or dry fingerprint images:
When the temperature is very cold or just after washing hands, fingerprints
often become very dry. In this case, the user should moisturize his/her
fingerprint simply by breathing on the fleshy pad of his/her fingertip prior
to placing his/her finger on the sensor. The moisture from his/her breath
transferred to his/her finger should help improve the recognition of his/her
fingerprint.
Conversely, if the fingerprint is too wet, the ridges and valleys are
rendered indistinguishable. The lack of recognizable minutiae causes wet
fingerprints to be rejected by the F707/708. This can be remedied simply
by swiping the finger on a clean dry towel or cloth.
How much pressure is required for a
good-quality fingerprint?
If too much pressure is applied to the sensor window, the finger’s ridges
become pressed together and create an indistinguishable image. Applying
too much pressure (similar to fingerprints that are too wet) will create a
“blurred” image which the F707/708 sensor might not recognize. It is
similar to using too much ink on a stamp; the stamp will create a smeared
image which is unrecognizable.
Conversely, if too little pressure is applied, the resulting image will be
similar to the dry fingerprint. Similar again to a stamp, if not enough ink is
used, the image will be barely recognizable.
Issues related to moisture and pressure are easily addressed. A little
practice is all that is needed for users to get the feel of it.
Be sure to maintain contact with the fingerprint sensor for 2 full
seconds, until the F707/708 responds. The F707/708 has both audio
and visual indicators which respond when the F707/708 senses a finger.

56
Proper Finger Placement
The user’s finger should completely cover the sensor. The finger should
be placed flat and in the center of the sensor. The finger should cover at
least 80% of the sensor as shown below:
The finger should NOT be placed in the following positions:

57
Identity Verification
The F707/708 will NOT record an employee’s attendance OR allow door
access UNTIL the individual’s identity is verified.
The F707/708 uses various means to verify a user’s identity:
1. Fingerprint Matching
2. Password Matching
FingerprintMatching
The F707/708 supports two methods of fingerprint matching, 1:N and 1:1.
1: N Fingerprint Matching
When using 1:N Fingerprint Matching, the F707/708 will place your
fingerprint (“1”) in its temporary memory and then compare it to ALL
(“N”) the fingerprint templates stored in the F707/708 database (up to
1000 templates).
By using 1:N matching the user enjoys the convenience of not having to
additionally enter his/her User ID. NO. prior to placing his/her finger on
the sensor. 1:N is basically 1-touch matching. It is the FASTEST and
EASIEST method of fingerprint matching.
1: 1 Fingerprint Matching (ID. NO +fingerprint)
When too many users’ fingerprints are not easily recognized by the
F707/708, the F707/708 can be set to perform 1:1 fingerprint matching.
1:1 matching requires the added step of first entering the user’s ID. NO.
However, 1:1 matching is more consistent than 1:N matching.

58
Password Matching
If too many users’ have difficulty with fingerprint matching, users can
register with passwords, instead of fingerprints.
Door-Access Considerations
The F707/708 is designed to work as an Access Control terminal and a
Time & Attendance recorder.
Door Access Control decisions are based upon “Who” the user is and
“When” the user is permitted door access.
The F707/708 will verify “who” the user is. But “when” the user is
actually permitted door access can be decided EITHER by the F707/708
OR a 3rd party Access Control panel.
If the F707/708 validates the identity of the user AND determines the user
is permitted door access AT THAT PARTICULAR TIME, the door will
release.
If the F707/708 verifies the user’s identity BUT determines the user is
NOT permitted door access AT THAT PARTICULAR TIME, the door
will NOT release.

59
Basic Concepts
This section explains and describes the functions and options of enrolling
the users;
•User Enrollment/Verification
•Match Threshold Levels
•User ID Numbers
•Authority (Status) Levels
The two most important functions are user enrollment and user
verification.
User Enrollment/Verification
Enrollment is the process of associating an ID number to the user’s
finger/s to create a template. This template is stored in the memory of
F707/708 for future verification.
During user verification, the stored template is compared to the current
fingerprint scan to confirm the user’s identity.
The enrollment process takes approximately 2-4 seconds.
Up to ten fingers can be enrolled for the same ID number, so the user may
have more verification options.
Ideally, we recommend enrolling one finger from each hand so that in
case of injury to one hand, the user can use the finger from the other
hand as a backup. It is recommended to enroll either index fingers
and/or middle fingers.
For users with extremely thin fingers, we recommend to enroll the
thumb. For users whose fingers are difficult to enroll or cannot be
enrolled, we recommend to enroll the password along with
fingerprint.

60
Match Threshold Levels
The Match Threshold is the degree to which a verification is performed to
ensure that the user is who he/she claims to be.
The Match Threshold Levels establishes a balance between False
Acceptance Rate (FAR) and False Rejection Rate (FRR). FAR measures
how often a non-authorized user is falsely recognized and granted access
to the system. FRR measures how often an enrolled and authorized user,
who should be granted access to the system, is denied on the basis that the
system did not recognize him/her.
Note that you cannot set match threshold levels on a per user basis. The
threshold-setting is universal, for the ENTIRE user-population.
If too many users are experiencing difficulty having his/her fingerprint(s)
read, we recommend using 1:1 matching (i.e. User first enters his/her User
ID, and then places his/her finger on the sensor for verification).
Raising the threshold increases security, while lowering it increases
throughput. Based on the quality of the fingerprints of the users, you need
to strike a correct balance.
So if too many users have fingerprint(s) having difficulty being read, the
match threshold level can (and should) be reduced.
Table1—1 Suggested Match Threshold Settings
FRR FAR One-to-many One-to-one
High Low 45 25
Middle Middle 35 15
Low High 25 10

61
User ID Numbers
Each fingerprint is assigned a unique User ID Number. This ID number is
used to call up the fingerprint template from the F707/708 database, each
time the verification is requested. ID numbers can also be called up via the
keypad
Authority (status) Levels
The F707/708 has four authority or status levels;
1. Users
People whose identity must be verified prior to releasing the
door or having his/her attendance recorded. Users have no
administrative privileges.
2. Enrollers
People who are authorized ONLY to enroll new users or delete
users from the system.
.
3. Administrator
People who can perform other operations, except set advanced
options and enroll administrators.
4. Supervisors
People who have access to ALL functions.
Note:
Until an actual Administrator is enrolled in the system, any user can
access the Menu System.

62

Plug the power adaptor to the main power supply or hit the Power button
on the keypad and the following “startup window” appears on the
F707/708.

Enrollment and Verification Procedures
This section describes how to enroll and verify users on the F707/708.
Note:
You normally must have Enroller, Administrator, or Supervisor
status to enroll users. But until an Admin is enrolled, all users have
access to all the menu functions.

63
Enrolling Users
The first “enroller” with a new F707/708 will have the capability of
enrolling other users. If you will be the administrator of the F707/708, be
sure to select “Administrator” when enrolling your fingerprint(s)”.
There are three modes of enrollment;
1. Fingerprint enrollment
2. Password enrollment
3. Fingerprint & password enrollment
The type of enrollment to be selected depends on the environment and how
easily the users’ fingerprints can be read by the F707/708.
Fingerprint enrollment should be used when the majority of users’
fingerprints can be read. This is typical of most office environments.
Password enrollment should be used for users who cannot be enrolled
nor verified by his/her fingerprint. It is not uncommon to have some
users whose fingerprints are simply too difficult for the F707/708 to read.
Fingerprint & Password enrollment allows users’ fingerprint(s) AND
password to be registered together, at the same time. Otherwise, these are
normally 2 separate operations.

64
User Management
The User Management menu allows you to enroll and delete users and
his/her respective fingerprint(s) and password. Some F707/708 models
can also enroll/verify Prox, HID and Mifare cards (aka PIN/FP cards);
Enroll User

Enroll Password
Enroll Fingerprint and Password
Enroll Admin

65
Enroll Users
Users (not including Admins, Supervisors or Enrollers) have NO
“administrative” access to the F707/708, but can gain door access and
have his/her attendance recorded.
Note:
Until an actual “Administrator” is enrolled in the F707/708, ALL
“users” enrolled on the F707/708 DO “temporarily” have
administrative access. Therefore it is important to enroll an
“administrator” on the F707/708 soon after initial installation.
“Users” can enroll with three methods;
•Fingerprints
•Passwords
•Fingerprints and Passwords
Enroll Fingerprint (for Users)
To start Fingerprint enrollment, press the MENU key on the F707/708.
