What is the Barcode System?

Barcodes are used internationally for retail to ensure that each barcode related to only one product. This system, created by George Laurer in the 1970’s. It helps to increase the efficiency and accuracy of the checkout process by ensuring that products all have unique international identifiers (barcodes).

Stores receive a product. They scan the barcode and enter information into their shop database. Typically stores record;

product name

product size


stock levels

When a customer brings a product to the checkout the barcode is scanned and it brings up the price and product name. It can also count down in the store inventory system alerting staff when they need to reorder more of a product.
