an LED array with thousands of CCD light detectors for the reflected light. The

entire bar code “image” is captured and then the array elements are transmitted

to form a signal pattern identical to the “scanned” pattern from a wand or laser.

There are no moving parts in a CCD scanner.

We offer the LI50 CCD as both a scanner (for attachment to a decoder) and an

integrated keyboard wedge reader. The LI50 can read a typical UPC code from

up to 7” away. The LI50 can read a medium density bar code up to 4” in length

(possibly longer if low density).
