Finger Enrollment Station
Quality and Content
When a new template is enrolled a “Quality” and “Content” reading is
generated, informing you of the overall quality of the scan.
Quality
The “Quality” reading refers to how well the ridge pattern is defined
within the finger image that was enrolled. See Figure HARDWARE-08
below.
Figure HARDWARE-9: Quality Readings
A high-quality scan should fill the entire sensor with a crisp, clear image
of the scanned finger. Dry or excessively dirty fingers can result in a low
quality reading.
Content
The “Content” reading refers to the amount of usable information the
sensor reads in the finger. See Figure HARDWARE-09 below.
