Figure HARDWARE-10: Content Readings
A finger template consists of the identifiable characteristics of your fin-
gertip. These characteristics vary depending on which pattern type your
finger contains (see “Finger Pattern Types” below for a definition of
each of the three pattern types). If these characteristics are not captured
when the template is created, the verification process will have little to
compare a scanned finger to.
The “Content” reading is based almost entirely on the proper placement
of your finger upon the sensor. Use of the Ridge Lock helps minimize
issues associated with poor finger placement and reduces the likelihood
that information-rich areas of the finger are outside the view of the
image. To use the Ridge Lock, place the joint of the first knuckle firmly
against the ridge located at the bottom of the sensor area.
Finger Pattern Types
There are three different types of patterns that make up an identifiable
fingertip.
