Every time you go to the supermarket or restaurant, borrow a book from the library or connect to Wi-Fi, rent a car or use public transport, you are interacting with barcodes. They’re literally everywhere, whether we notice them or not.

Barcoding originally appeared in grocery stores. And since 1951, when they were invented, barcodes have become a universal symbol of trade.

So why are barcodes so popular? Are they so essential to run an online store? Where to get them, and what format is better? We’ll cover these questions in this blog post.

What is a barcode?

A barcode is a scanner-readable label containing encrypted information about a product. Barcodes are designed like fingerprints; they have a unique pattern that identifies the product in the store.

As a rule, barcodes are used directly at the point of sale, inventory management systems, or warehouses to quickly distinguish a product and determine its price, material, asset, etc.

Types of barcodes

Barcodes come in two types: 1D (1-dimensional) and 2D (2-dimensional).

One-dimensional barcodes look like a series of black and white vertical lines of varying widths and numbers below them. You’ve undoubtedly seen them on grocery store packaging, shipment labels, or book covers.

Barcodes explained: types, benefits, and how to create them

1D barcodes need to be connected to a database so that when they are scanned, they can convey information about a product, typically its name, type, size, and color. This particular type is the most common format in stores.

Two-dimensional barcodes are designed as a set of black and white patterns and shapes arranged in a square. Probably the most famous example of a 2D barcode is the QR code. By scanning the QR code with your smartphone, you can access digital content, log in to a website and, sometimes, verify your identity.

Example of a barcode

2D barcodes are more complex than 1D because they encrypt more data. While 1D types primarily store text, a 2D barcode reader can display information such as product quantities, images, and website URLs.
