2. Finger Print Sensor
a. Cautions
1.
Never pour the glass cleaner directly on the sensor window
2.
Never use alcohol-based cleaners
3.
Never submerge the sensor in liquid
4.
Never rub the window with an abrasive material, including paper
5.
Do not poke the window coating with your fingernail or any hard item, such as a pen.
b. Principle
The finger print sensor software never stores fingerprint images. The finger print sensor
software creates a fingerprint template, which is a highly compressed and digitally encoded
mathematical representation of fingerprint features. This template is created when a user
registers a finger and is stored in an encrypted file. When the user later touches the fingerprint
reader to authenticate, a new template is created and compared to the “registered” template. If
there is a match, the authentication is successful.
c. Finger Print Recognition
In order for the sensor to acquire a good image of your finger, you must place the pad of
your finger but not the tip in the center of the sensor window, and apply gentle, even pressure.
Do not “roll” your finger as usually practiced in the traditional ink and paper fingerprint taking
technique. 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.
d. Sensor Activation
The LED behaviors are described in the following table.

Failure to connect to a self-powered USB port will cause non-operation of the sensor. If
you activate your terminal’s power-saving functionality but your third party application does
not support this, then your fingerprint sensor will enter “sleep mode” even though your
workstation does not. If this occurs, you will need to reboot the system. Please check with your
application developer for compatibility.
e. Cleaning the Sensor
Depending on the amount of use, the sensor window may need to be cleaned periodically.
To clean it, apply the sticky side of a piece of adhesive cellophane tape on the window and peel
it away as in the drawing at right.
Under heavy usage, the window coating on some sensors may turn cloudy from the salt in
perspiration. In this case, gently wipe the window with a cloth (not paper) dampened with a
mild ammonia-based glass cleaner.
