Profile: Zygology Systems Ltd deals with automatic identification products and consumables. We specialize in innovation and best practice to solve the most difficult labeling and identification problems. Our CCD scanners have a row of tiny light sensors and can view a whole barcode at once. They contain no moving parts, so are very robust. Laser scanners use a mirror to scan a laser beam back and forth across the barcode. They are quick, accurate and can read smaller bar codes than CCD scanners.
