How to swipe the finger
Using the following steps when swiping ngers for ngerprint 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.
n Avoid swiping with the nger stiff or pressed-on too hard:
Fingerprint reading may fail if the center of the ngerprint is not touching
on the sensor, or when nger is swiped while pressing hard. Make sure
that the center of the ngerprint is touching the sensor before swiping.
n Conrm the center of the ngerprint whirl before swiping:
The thumb’s ngerprint has a bigger whirl, which is prone to misalignment
and distortions. This will cause difculty in registration and a drop in the
authentication success rate. Always conrm the center of the ngerprint
whirl so that it is swiped along the centerline of the sensor.
n When ngerprint reading is not successful:
There is a possibility of authentication failures if the nger is swiped too
quickly or too slowly. Follow the onscreen instructions to adjust the speed
of the swipe.
