Appendix B: Biometric Recognition Performance
Below is a list of the most common issues adversely affecting the performance of the biometric
recognition systems configured in your BioAxs 9750™ access panel.
Fingerprint Recognition Performance Issues
•
The sensor is having difficulty acquiring an image of your finger; the sensor window may
need cleaning, as described in “Cleaning the Sensor” (above).
•
You may not be touching the sensor correctly. In order for the sensor to acquire a good
image of your finger, you must place the pad of your finger—not the tip—in the center of
the oval window, and apply gentle, even pressure. Do not “roll” your finger. Pressing too
hard will distort your fingerprint.
•
Pressing too lightly will not expose a large enough area of your finger. Also, make sure
to hold your finger on the sensor until you see the sensor light blink; this may take longer
for dry fingers. Then, lift your finger. Although you may use any finger with the sensor,
your index finger of either hand works best.
•
If the sensor is capturing your finger image (as indicated by the sensor blink) and you
have tried all the above suggestions, you may need to reregister your finger or try
registering a different finger.
