When you walk into a retail store, have you ever wondered how the products are efficiently tracked and managed? The answer often lies in those mysterious black and white lines printed on product packaging, known as barcodes. In this beginner's guide, we'll unravel the basics of barcodes, with a special focus on GS1 barcodes.

What is a Barcode?

A barcode is a method of representing data in a visual, machine-readable form. It consists of a sequence of parallel lines, typically in black and white, that can be scanned and decoded to retrieve information quickly. Barcodes are widely used for inventory management, product identification, and more.

Types of Barcodes

There are various types of barcodes, each designed for specific purposes. Two of the most common barcode formats are:

Barcode Type Use Cases
1. GS1 Barcode Primarily used in retail and supply chain for product identification, traceability, and inventory management.
2. UPC Barcode Commonly seen on consumer products for quick and accurate point-of-sale transactions.
