What Is A Barcode Scanner?

Definition

A barcode scanner is a device that can read a barcode, identify what's on it and process the information. The device scans the barcode to retrieve all of the product information, including its price and size, which can then be stored in a computer database. The information is then used to generate marketing reports or order more products. These scanners are an important tool not just for point-of-sale devices but also for inventory management.
