Optical character recognition (OCR) products are used to read text from paper and translate it into data that can be manipulated by computers. Optical scanners, optical wands, and optical software are examples of optical character recognition (OCR) products. Optical character recognition (OCR) is often confused with digital character recognition, but represents a different technology. Optical character recognition (OCR) products reproduce characters via optical compositing with lenses and mirrors. OCR systems contain many different components; however, the primary mechanism of an OCR system remains the OCR scanner. The most common use of OCR scanners is in reading bar codes that printed on many commercial and consumer products. Another typical use of OCR scanning is in mail-sorting centers.
