Hi Tapasiitkgp, the barcode is like out unique identity card or driving license number. Those combination of numbers only exist once and it is use to represent something. Similar to barcode, it is just barcode is mostly use for product like milk powder, cloth's tag, etc. With the uniqueness features, it will helps a lot especially for those market or hypermarket because they just need to scan, then the info will auto populate out, of course, with the price.
