Biometrics Fingerprint Reader
High quality fingerprint templates are imperative for the security of the biometric
security system. Low quality fingerprint templates can impact future read rates.
Therefore, using the Biometrics Module should be done very carefully. In case of
inexperienced users who are using the module for the first time, the process should be
assisted (guided) by an administrator or experienced user.
Using the Biometrics Reader
Place your thumb/finger flat and straight on the sensor. If this is not possible, try to
place your thumb/finger on the sensor in the same angle every time.
Under normal usage conditions dirt, residue, oils, and other materials can collect on
users’ fingers. This can possibly cause poor collection of fingerprint data, which can
cause performance degradation. For the best results it is recommended that the user
keep their fingers relatively clean and free of residues that may alter the sensor
performance.
Scotch tape can be used to clean fingers. Adhere the tape to the finger and then pull it
off.
Cleaning the Sensor
Before each authentication, it is recommended that the user first clean the sensor. Place
adhesive tape onto the sensor and then pull it off. This assures that residue from
previous usage is removed.
Caution: Do not use abrasive materials to clean the sensor.
