Barcode Scanner / Barcode Reader
A Barcode Scanner, also known as a Barcode Reader or Barcode Gun, is a device used to read information encoded in barcodes. Barcode scanners typically have an illuminating device that shines light onto the barcode. The light-sensitive component receives the reflected light. Different intensities of reflected light correspond to the varying depths of lines in the barcode. The decoding device then converts these patterns into a set of digital signals.
