Barcode is an identification method for products. It is a representation of data of a product in the form of parallel lines changing in width and spacing between them. It is readable by a machine and is widely used in supermarkets, malls, stores, etc. for automatic identification of the product. Barcode is a machine-readable image which quickly and rightly identifies a product. It is a unique global identification system which is used in the supply chain for goods like the product, logistic goods, entities of trade, location, documents, etc.
1D barcodes represent data by changing the widths and spacing of parallel lines, and may be referred to as linear. These include some or most well recognized barcode types such as the UPC and EAN code types.
1. UPC CODE: UPC barcodes are used to label and scan consumer articles at points-of-sale around the world, mainly in the United States, but also in the United Kingdom, Australia, New Zealand and other countries. The UPC-A changing encodes 12 numerical digits while UPC-E is a smaller variation, which encodes only 6 numerical digits.
2. GS1 DATABAR: GS1 Data Bar barcodes are used by retail outlets to identify consumer coupons, produce as well as small articles in the healthcare industry. They are smaller than typical consumer-facing barcodes. GS1 Data Bar was introduced in 2001 and became the mandated barcode type for retail coupons in the US.
Two-dimensional, or 2D barcodes, represent data using two-dimensional symbols and shapes. They are similar to a linear 1D barcode but can represent more data per unit area.
Barcodes are often overlooked as a method for deducting costs and saving time. A valuable and practicable choice for businesses looking to improve efficiency and reduce overhead, barcodes are both cost-effective and reliable.
