A barcode scanner is an electronic device used in shopping malls, departmental stores, inventories to scan the barcode behind every product. These cordless phone-like devices scan the codes behind the products and obtain the information embedded in these codes. Barcode scanners find ample usage in all kinds of stores. They are also known as price scanners or point-of-sale (POS) scanners.

How Does It Work?

The working process of a barcode scanner is very simple. It is pointed towards the barcodes printed behind the products, with a beam of red light directed towards them. This is how the data incorporated within the barcodes are read by the scanner.
