You must have bought a product on which the barcode is printed. Have you ever wondered how barcodes works?
A Barcode has a unique combination of lines. This gives information about the product on which it is printed. This information can be read by the barcode scanner and then be translated into text on the computer screen, also this information is stored in the POS system which is made by that retailer. The barcode scanners are of different types based on their efficiency to read barcodes.
Now that Barcodes are in numerical form, Why do we need them? This is because barcodes play a key role in supply chains, enabling parties like retailers, manufacturers, transport providers and hospitals to automatically identify and track products as they move through the supply chain.
Barcodes are managed and allotted by a Central Authority named GS1. It raises money by selling the barcode patterns to different companies.GS1 has allotted each country a unique starting code. For India, that code is 890.
We will discuss about QR codes in the next blog. Till then stay tuned.
