Section 02
Fingerprint enrollment guidelines

2.1 Fingerprint enrollment guidelines
The HID® Signo™ Biometric Reader 25B is capable of extracting quality features even from fingers with poor conditions.
Nevertheless, correct placement of fingers on the sensor during enrollment helps consistency in fingerprint recognition.
Adhere to the following general guidelines and Signo 25B specific guidelines to enroll optimal fingerprint images from a
user’s finger to improve recognition performance.
2.2 General guidelines
Choose the ideal fingers to enroll
For correct positioning of finger on the sensor, it is recommended to use index or middle fingers.
Correct positioning of finger on sensor
lMaximum contact area: Place your finger to completely cover the sensor with maximum contact surface.
lPlace on the center: Position center of fingerprint (core) on the center of the sensor.
lHold your finger still: Once you place your finger on the sensor, hold finger still until prompted to remove finger.
Note: The positioning of the finger on the sensor is important. If the finger does not cover the maximum contact
area, or if the finger is not held still the enrollment will not be successful. For this reason, this product is
not recommended for use with children under the age of 12.

Sensor cleaning
The fingerprint sensor can become soiled by user’s fingers, dust, or other sources. This contamination may affect image
quality, degrading authentication performance. It is therefore recommended that you periodically clean the Signo 25B
sensor.
In order to avoid scratching the sensor surface use soft lint-free material (or a cotton swab), with gently movements to
clean the capture area.
Note: Optical cleaning products that are used for glasses or cell phone glass surfaces can be used to clean the
sensor area.
Caution: Do not use acidic liquids or abrasive materials to clean the sensor.
Disinfecting the sensor
To disinfect the sensor, use Ethanol or Isopropanol in a concentration of up to 70% on a soft, lint-free cloth or a cotton
swab and gently wipe the capture area.
If a haze is left on the fingerprint sensor, gently dab the area with a soft cloth, dampened with a mild ammonia-based
glass cleaner. Do NOT wipe the area.
Caution:
lDo not pour cleaning fluid directly on the fingerprint capture area.
lDo not submerge the sensor in liquid.
lDo not rub the fingerprint capture area with any abrasive material, including paper.
Note: To minimize the spread of germs, it is recommended to wash or sanitize your hands before and after using
the fingerprint reader.
Common reasons for enrollment failure
Problem Solution
Finger is too dry or dirty Rub the finger in the palm of your hand to moisten/clean it
Finger applied too lightly Place finger firmly and flat onto the sensor surface
Finger positioned incorrectly Your finger must cover most of the sensor window
Finger removed or moved during the scan
process
Hold your finger still and do not slide it on the sensor window until the scanning process is
complete
Injury or wear has changed the fingerprint
pattern
Contact the administrator as you may need to enroll another finger

2.3 Fingerprint enrollment best practices for Signo Biometric Reader 25B
1. Insert your finger into the Signo 25B sensor area so the finger tip touches the back wall and rests softly on the
sensor slope.
2. Slide your finger down so that it completely covers the sensor window contact surface.
3. Apply gentle pressure on the sensor to slightly flatten your finger and expose a maximum usable area.
4. Keep your finger still until prompted to remove finger.

Acronyms and terminology

Term Definition
Authentication Mode
(Signo 25B)
Template on Card: The Signo 25B is waiting for a Credential (Card) to be presented. It retrieves
all the biometric templates from the credential.
If the presented finger matches the biometric templates retrieved from the credential a Grant
Access is recommended. This is a 1:1 Verification match against Template on Card (TOC). The
sensor is not armed (blue light off) until the Credential is presented.
Card + Finger: The Signo 25B is waiting for a Credential (Card) to be presented. It looks up the
user ID and all associated biometric templates in it’s local device database. If the presented
finger matches the biometric templates retreated from the local database a Grant Access is
recommended. This is a 1:1 Verification match against Template on Device (ToD). The sensor is
not armed (blue light off) until the Credential is presented.
Finger Only: The Signo 25B is waiting for a finger to be presented that is stored in its local device
database. If the presented finger matches one stored in the database a Grant Access is
recommended. This is a 1:N Identification match against Template on Device (ToD). The sensor
is always armed (blue light on).
Card Only: The Signo 25B is waiting for a Credential (Card) to be presented. It reads the PACS
data only and always recommends a Grant Access. The sensor is never armed (blue light off).
Card Only (or) Finger Only: The Signo 25B is waiting for either a Credential (Card) to be
presented or a finger, stored in its local device database, to be presented. This authentication
mode is particularly useful during initial enrollment setup.
Biometric spoofing Biometric spoofing is a method of fooling a biometric identification management system. An
artificial object (for example, a fingerprint mold made of silicon) is presented to the biometric
scanner that imitates the unique biological properties of a person which the system is designed
to measure.
BLE Bluetooth Low Energy (formerly marketed as Bluetooth Smart) is a wireless personal area
network technology.
ERR The Equal Error Rate (EER) is the common value indicating that the proportion of false
acceptances (FAR) is equal to the proportion of false rejections (FRR). The lower the EER value,
the higher the accuracy of the biometric system.
False Accept Rate (FAR) The False Accept Rate (FAR) is the measure of the likelihood that the biometric security system
will incorrectly accept an access attempt by an unauthorized user.
False Reject Rate (FRR) The False Reject Rate (FRR) is the instance of a security system failing to verify or identify an
authorized person.
FTA Failure To Acquire. The biometric system failure to extract usable identification data from a
biometric sample.
Identification (of Identity) Typically finding a matching template in a large database of templates. 1:N matching.
LFD Live Finger Detection. This is used in some markets instead of Spoof. It is also used to refer to
insuring a severed finger is not being presented at the sensor.
MINEX Minutia Interoperability Exchange. The MINEX program is dedicated to the evaluation and
development of the capabilities of fingerprint minutia matchers running on ISO/IEC 7816 smart
cards.
