Product Description
The 1229L is a retail terminal designed to present information to the operator and the customer. The 1229L is available in serial and USB versions. The 1229L functionally consists of a 12.1” LCD main display with a touchscreen, an optional vacuum fluorescent display (VFD) Customer Display, an optional fingerprint reader (USB version only), an optional credit card reader, and a 6 port USB (USB version only) Hub. The main display element is a 12.1 inch diagonal SVGAresolution (800x600) LCD display. The main display will consist of an LCD Display and touchscreen. Three types of touchscreens can be selected in the 1229L as options. They are AccuTouch, Intellitouch, and IR. The Customer Display is a twenty character two line vacuum fluorescent display (VFD). The VFD can display 40 characters 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 verifica- tion (authentication of registered users). The fingerprint reader uses the SEIR method and CMOS image sensor to capture high contrast, high resolution fingerprint images. A series 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 previ- ously stored sample. The entire matching process takes roughly one second. There is a fingerprint reader available in the USB version of the 1229L and none in the serial version of the 1229L.
