The barcode scanners consist of an internal decoder and a cable, which are connected to the computer through compatible ports. It consists of a light source, a lens and a photo conductor translating optical impulses into electrical ones. The sensor of the barcode scanner detects the reflected light from the illumination system and generates an analog signal with varying voltage which represent the intensity or lack of intensity of the reflection. The converter changes the analog signal to digital signal which is fed to the decoder.

Using bar code technology in stores can help to solve all these problems. It lets you keep a centralized record on a computer system that tracks products, prices, and stock levels. You can change prices as often as you like, without having to put new price tags on all your bottles and boxes. When purchasing a bar code scanner you want to ensure that it has the right wireless connections. This usually depends on how you to collect and input data into your inventory system.
