dicult to place in the correct position
How to place a nger on a sensor
• Place a nger such that it completely covers
the sensor area with maximum contact.
• Place core of the ngerprint at the center of
the sensor. The core of a ngerprint is a center
where the spiral of ridges is dense. (Usually core
of ngerprint is the opposite side of the lower part
of a nail.)
• Place a nger such that the bottom end of a
nail is located at the center of a sensor.
