BARCODE SCANNER
Barcodes are used to encode information in a visual pattern readable by a machine only. Barcodes are used for a variety of reasons like tracking products, prices, and stock levels for centralized recording in a inventory management software.
A barcode scanner usually consists of three different parts including the illumination system, the sensor, and the decoder. In general, a barcode scanner “scans” the black and white elements of a barcode by illuminating the code with a red light, which is then converted into matching text. More specifically, the sensor in the barcode scanner detects the reflected light from the illumination system (the red light) and generates an analog signal that is sent to the decoder. The decoder interprets that signal, validates the barcode using the check digit, and converts it into text. This converted text is delivered by the scanner to a computer software system holding a database of the maker, cost, and quantity of all products sold.

Given below are different types of available barcode scanners with a little insight into how each works.
i)Pen-type Reader: consists of a light source and a photodiode on the tip of the pen.
ii)Laser Scanner: works similarly to a Pen-type Reader but uses a laser beam.
iii)Camera-based Reader: installed with camera and image processing techniques in the reading of barcodes.
iv)CCD Reader: has several light sensors to scan barcodes.
v)Omni-Directional Barcode Scanner: highly advanced and very efficient in decoding badly printed, & crumpled barcodes on products.
