<u><em>Differences between barcode reader and character recognition devices:</em></u>
Barcode Reader or Barcode Scanner:
- Barcode Scanner scans the data by brightening the barcodes usingSensor
- The analog signal is then converted into digital signal by Converter.
- The Decoder calculates the converted data and sends valid data to the computer.
Character Recognition Devices (OCR):
- OCR scans the physical document and converts them into two-coloured format.
- The darker and lighter area are identified as characters and blanks respectively.
- The common methods used are: Pattern Recognition and Feature Detection.
