With the advent of technology, many businesses have opted for barcode technology as a means of scanning and reading the items available in stores. From purchasing items to renting a car to attending major events, the industrial barcode scanner PDA is found everywhere. This system helps the businesses in tracking information about the items rapidly and instantaneously, which, in, turn increases the productivity and sales of a business.

They are used for numerous reasons including tracking products, prices, and stock levels for managing the inventory. A barcode scanner is equipped with three parts including an illumination system, sensor, and decoder. It scans the black and white elements of a barcode by illuminating the code with a red light, which is further converted into a matching text. Moreover, the sensor is responsible for detecting the reflected light from the illumination system and hence, generates a signal that is sent to the decoder. The decoder finally interprets the signal, validates it, and converts it into the text.
