How to place a finger on a sensor
(1) Place a finger as it completely covers the sensor with maximum
contact.
(2) It is better to place the core part of a fingerprint to the center of
a sensor.

People usually tend to place only the top end of a finger

Where is the core (center) of a fingerprint?

A peak where spirals of fingerprint ridges are dense

Usually opposite to lower part of a nail

It is recommended to place a finger as the lower part
of a nail is located at the center of a sensor
(3) If a finger is placed as in the right picture, only a small area of a
finger is captured. So it is recommended to place a finger as in the
left picture.
