A barcode scanner is an instrument that basically reads printed barcodes on products. A code scanner usually has a red light reflection, which sends the symbols back to a converter. The converter has a readable code which then passes it to a decoder that translates these codes into a kind of text that makes it understandable to people. A barcode scanner app was made for people to be able to use their iPhones to scan codes for particular products. This helps a lot of people save money when it comes to making purchases because the consumer is warned of the price beforehand.

History of the Barcode Scanner

Owners of groceries and supermarkets experienced growth of their businesses and felt an urge to stock more items on shelves so that their customers could shop for everything under one roof. It became somehow difficult for them to keep records of what is available on their shelves and what is not. They used to count items that were on shelves manually to analyze what is in stock and what was out of stock.
