How to 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.

2.While lightly touching the sensor, swipe the finger towards you until the sensor surface becomes visible.

3.Ensure the center of the fingerprint is on the sensor when swiping the finger.

Slide the finger over the recognition sensor

■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.
