How to Swipe your Finger
Using the following steps when swiping fingers for fingerprint registration or
authentication will help to minimize authentication failures:
Align the first joint of the finger to the center of the sensor. Lightly touch the
sensor and swipe finger levelly towards you when in portrait mode, and
sideways when in either landscape mode or Laptop mode.
While lightly touching the sensor, swipe the finger towards you when in
portrait mode, and sideways when in either landscape mode or Laptop
mode until the sensor surface becomes visible.
The following illustrations show the recommended way to swipe your finger
over the fingerprint sensor.

■
Avoid swiping with your finger stiff or pressed too hard onto the sensor,
and take care to ensure that the center of the fingerprint is touching the
sensor before swiping. Either of these conditions may cause fingerprint
reading to fail.
■
Check the center of the fingerprint whirl before swiping and then
ensure this is swiped along the center line of the sensor.
■
There is a possibility of authentication failures if the finger is swiped too
quickly or too slowly - follow any on-screen instructions to adjust the
speed used during the swipe process.
