How to enroll a fingerprint
In order to improve the fingerprint authentication rate, register the fingerprint correctly. BioEntry W2 can recognize a fingerprint
even if the angle and position of a user's fingerprint input change. If you register the fingerprint with attention to the following
matters, the authentication rate can be improved.
Selecting a finger for fingerprint input
• In preparation for the case that 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 registered.
• 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 finger 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
Place the finger with the fingerprint to be registered on the fingerprint authentication unit and press the finger gently for
better authentication.
2
After a beep sounds, scan the fingerprint of the registered finger again (scan the fingerprint of a finger to be registered
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 has decreased or the angle of finger has warped, fingerprint
authentication may not be performed.
When the fingerprint recognition fails
BioEntry W2 can recognize a fingerprint regardless of a change of 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 registered fingerprint often may have not been scanned correctly, so register the fingerprint again according to ‘Cautions
for enrolling a fingerprint’.
