How the Swipe the Finger
Using the following steps when swiping fingers for fingerprint registration or
authentication will help to minimize authentication failures:
1. Align the first joint of the finger to the center of the sensor. Lightly touch
the sensor and swipe finger levelly towards you.
While lightly touching the sensor, swipe the finger towards you until the
sensor surface becomes visible.
Ensure the center of the fingerprint is on the sensor when swiping the
finger.
■ Avoid swiping with the finger stiff or pressed-on too hard
Fingerprint reading may fail if the center of the fingerprint is not
touching on the sensor, or when finger is swiped while pressing hard.
Make sure that the center of the fingerprint is touching the sensor
before swiping.
■ Confirm the center of the fingerprint whirl before swiping
The thumb's fingerprint has a bigger whirl, which is prone to
misalignment and distortions. This will cause difficulty in registration
and a drop in the authentication success rate. Always confirm the
center of the fingerprint whirl so that it is swiped along the centerline of
the sensor.
■ When fingerprint reading is not successful
There is a possibility of authentication failures if the finger is swiped too
quickly or too slowly. Follow the onscreen instructions to adjust the
speed of the swipe.
