2.2 Fingerprint Collection Method
The place of finger affects the fingerprint information collected a lot
because of the area sensor used in the fingerprint reader. The following
are some tips for fingerprint collection.
Placement of Finger
Try to place the finger in the center of the sensor. If the fingerprint stored
in the template is left skewed when collection, and then the user press his
finger too right when identification, the identification will be failed,
because the overlap area between the template and the recorded
fingerprint information is too small to pass the user.
Area between Finger and Sensor
The touch area between finger and sensor decides the information
content of the collected fingerprint. The more information the device
sensed, the higher of the pass rate.
Thumb, forefinger, middle finger are suggested to use in order to improve
fingerprint identification rate.
