Product Description

The 1529L is a retail terminal designed to present information to the operator and the

customer. The 1529L is available in serial and USB versions or combo touch monitor.

The 1529L consists of a 15.0” LCD main display with a touchscreen and the following

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.
