Points to note about the Fingerprint Sensor
Failure to follow these guidelines might result in (1) damage to the sensor
or cause sensor failure, (2) finger recognition problems, or lower finger
recognition success rate.
■ Do not scratch or poke the sensor with your nails or any hard or sharp
objects.
■ Do not press the sensor strongly.
■ Do not touch the sensor with a wet finger or any wet objects - keep the
sensor surface dry and free from water vapor.
■ Do not touch the sensor with a soiled or dirty finger as minute foreign
particles of dust and dirt may scratch it.
■ Do not paste stickers or write on the sensor.
■ Do not touch the sensor with a finger or any other object which may
have a build-up of static electricity on it.
■ 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.
