How to enroll a fingerprint correctly
In order to improve the fingerprint authentication rate, enroll the fingerprint correctly. BioLite N2 can recognize a fingerprint even
if the angle and position of a user's fingerprint input change. If you enroll a fingerprint with attention to the following matters, the
authentication rate can be improved.
Selecting a finger for fingerprint input
• In preparation for a situation in which the fingerprint of a specific finger cannot be used, for
example if the user is lifting a load with one hand or a finger gets hurt, up to 10 fingerprints
for each user can be enrolled.
• In the case of a user whose fingerprint cannot be recognized well, the authentication rate
can be improved by enrolling the same finger twice repeatedly.
• If a finger has a cut or the fingerprint is blurry, select another finger for the fingerprint.
• It is recommended to use the index f
inger or the middle finger when scanning the
fingerprint. The authentication rate can be reduced if it is difficult to place another finger at
the center of fingerprint sensor accurately.
Fingerprint enroll method
1
When a message saying “Place your finger on the sensor.” is displayed on the LCD screen for enrolling the fingerprint, place
the finger with the fingerprint you wish to enroll on the fingerprint authentication unit and press the finger gently for better
authentication.
2
When the re-input screen is displayed after a beep sound, scan the fingerprint of the enrolled finger again (scan the
fingerprint of a finger to be enrolled twice).
NOTE
Cautions for enrolling a fingerprint
When a fingerprint is recognized, it is compared with the initially registered fingerprint, so the initial fingerprint enroll is the most
important. Pay attention to the following matters when enrolling the fingerprint.
• Place the finger deep enough to contact with the sensor completely.
• Place the center of the fingerprint in the center of the sensor.
• If a finger has a cut or the fingerprint is blurry, select another finger for the fingerprint.
• Scan the fingerprint correctly without moving according to the instruction on the screen.
• If you make the finger upright so that the contact area with the sensor is decreased or the angle of finger is warped, fingerprint
authentication may not be performed.
When the fingerprint recognition fails
BioLite N2 can recognize a fingerprint regardless of a change in season or finger condition. However, the authentication rate may vary
according to the external environment or fingerprint input method.
If the fingerprint authentication cannot be done smoothly, it is recommended to take the following measures.
• If the finger is smeared with water or sweat, dry off the finger and then scan the finger.
• If the finger is too dry, blow your breath on the fingertips and then scan the finger.
• If the finger has a cut, register the fingerprint of another finger.
• The initially enrolled fingerprint often may have not been scanned correctly, so enroll the fingerprint again according to ‘Cautions for
enrolling a fingerprint’.
