General Information
CCD (charged coupled device) scanners are,
depending on model type, either contact or near
contact scanners. Because CCDs scan
automatically when approaching or pointing at a
bar code label, their operation is intuitive. CCDs
read difficult labels found on curved or irregular
surfaces and perform especially well in high
ambient light conditions. They are a cost-
effective, inexpensive alternatives to other
scanning technologies.
Featuring state-of-the-art imaging technology,
CCDs use the same sensor found in facsimile
machines or video camcorders. The CCD images
the bar code label, then converts the digital signals
into data the host computer can understand. By
capturing the bar code image all at once, the
scanner provides a fast, highly accurate read rate.
Miniature surface mount electronics make up the
CCD scanners solid state construction. CCDs have
no moving mechanical parts and provide years of
trouble-free operation.
