Main principles
Acquisition needs to be done with extreme care, in order to:
get the best image quality
increase recognition performance
reduce recognition time
Then, it is highly recommended to:
Maximize the contact between the fingerprint and the sensor
Exert firm, but not excessive, finger pressure on the surface of the sensor
Do not press too hard
Do not slide nor roll the finger across the sensor
Do not move the finger during acquisition
Wait for the extinction of sensor backlight before removing the finger
