A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes.A bar code scanner reads bar codes.Bar codes contain data, typically numeric or alphanumeric data. While bar codes may all look the same to people, the data and even the "symbologies" are different. A bar code symbology is sort of like the language of the bar code, and there are many types: UPC, EAN, Code 39 (also called 3 of 9) and many others.
A bar code is used to identify a product or item. That's all. Other information associated with that bar code is held on the computer server that is linked to the bar code scanner. That other information could include what the item is, its price, brand, size/weight, and many other particulars. The scanner is able to identify the item, and once the bar code has been used for that, the computer server does the rest.
