Product Description
The ET1529L is a retail terminal designed to present information to the operator and the
customer. The ET1529L is available in serial and USB versions or combo touch monitor.
The ET1529L functionally consists of a 15.0” LCD main display with a touchscreen, an
optional 12.1 inch Lcd, customer display, an optional vacuum fluorescent display (VFD)
Customer Display, an optional fingerprint reader, an optional credit card reader, and a 6
port USB (USB version only) Hub. The main display element is a 15.0 inch diagonal
XGA resolution (1024x768) LCD display. The main display will consist of an LCD
Display and touchscreen. Three types of touchscreens can be selected in the 1529L as
options. They are AccuTouch, Intellitouch, and IR. The 12.1 inch second display will
consist of the LCD Display and touchscreen(option). The Customer Display is a twenty
character two line vacuum fluorescent display (VFD). The VFD can display 40 charac-
ters in a 20 character 2 row format. Each character is made by various fonts using a 5x7
pixel format matrix.
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 ET1529L.
