Product Description

optional peripherals: customer display, vacuum fluorescent display (VFD) Customer
Display, fingerprint reader, barcode scanner, credit card reader, and a 6 port USB (USB
version only) Hub. The main display element is a 15.0 inch diagonal XGA resolution
(1024 x 768) LCD display. The main display will consist of an LCD Display and
touchscreen. Four types of touchscreens can be selected in the 1529L as options. They
are AccuTouch, Intellitouch, and carrollTouch and Acoustic Pulse Recognition.
The fingerprint reader translates illuminated images of fingerprints into digital code for
further software processing, e.g. enrollment (fingerprint registration) and verification
(authentication of registered users). The fingerprint reader uses the SEIR method and
CMOS image sensor to capture high contrast, high resolution fingerprint images. A se-
ries of algorithms extracts minutiae data from the image, mapping the distinguishing
characteristics of fingerprint ridge ends, splits, dots, and arches. To identify or verify a
fingerprint, a proprietary matching algorithm compares the extracted minutiae points
from the input fingerprint on the optical module to a previously stored sample. The
entire matching process takes roughly one second. There is a fingerprint reader avail-
able in the USB version of the 1529L.
