2D Barcodes Ultimate Guide: Everything You Should Know

Feeling overwhelmed and lost in the maze of marketing strategies? 2D barcodes can help you navigate your way through it.

Unlike traditional barcodes, these two-dimensional barcodes pack a wealth of data into a compact grid.

But how do you access this hidden information, and what types of two-dimensional barcodes are there that you can use?

In this article, we’ll explain how they work, explore the different types, and show you how to scan them with your smartphone.

You’ll also discover how to use the best QR code generator available online to create your own QR codes easily.

What is a two-dimensional (2D) barcode?

A two-dimensional barcode surpasses traditional barcodes in data storage capacity. It compresses information into a smaller area, offering a denser storage space.

The versatility of two-dimensional barcoding finds application across various sectors, from inventory management and shipment tracking to sharing website links on business cards and facilitating swift access to product details on packaging.

Users can also use this technology by downloading the best barcode scanner app on their smartphones. These apps enable them to decode two-dimensional barcodes on the go and conveniently access the embedded information.

How do 2D barcodes work?

A two-dimensional (2D) barcode encodes information in a grid or matrix format, allowing it to store far more data than traditional one-dimensional (1D) barcodes, which only use simple lines of varying widths.

Two-dimensional barcodes can hold diverse data types, including website URLs, files, text messages, contact information, and even images and videos. Think of them as tiny data vaults.

The scanner captures the two-dimensional barcode image and translates the encoded data into a readable format, providing instant access to the stored information.

Unlike one-dimensional barcodes that need a specific scanning angle, two-dimensional barcodes are omnidirectional and can be scanned from virtually any angle. This versatility makes them much more user-friendly.

One of the most popular 2D barcodes are QR codes. You can create them using a free QR code generator online.

A guide on how to scan 2D barcodes

Scanning a two-dimensional barcode is easier than you think. Most smartphones nowadays are equipped with camera apps that serve as barcode scanners. Here’s a quick guide:

• Download a barcode scanner app.

Note: This is only applicable if your smartphone does not have a built-in scanner.

• Open your smartphone’s camera app.
• Point your camera at the two-dimensional barcode. Make sure it’s well within the frame.
• Wait for the app to detect the code, interpreting the pattern of light and dark modules.
• Click the popup link to open the encoded data.

It is also worth taking note that many two-dimensional barcodes are designed with “error correction” capabilities.

This feature enables the scanner to accurately decode the information even if the code is slightly damaged or scratched.

As a result, users can enjoy a seamless and dependable scanning experience.

Frequently asked questions

Is 2D code same as QR code?

A 2D code is a broad term for any square barcode that stores information in two directions.

QR codes are a specific type of 2D code, identifiable by their distinctive black and white squares. So, while all QR codes are 2D codes, not all 2D codes are QR codes.

What’s the difference between 2D and 1D barcodes?

The main difference between one-dimensional and two-dimensional barcodes is their information storage capacity. One-dimensional barcodes use lines to store limited information.

While two-dimensional barcodes, such as QR codes, use squares, dots, and patterns to hold much more data, like website links, tickets, or even contact details, making them more versatile and powerful.

What is the difference between 2D and 3D barcodes?

Two-dimensional barcodes use a two-dimensional grid of squares, dots, or hexagons that stores data by converting information into a series of small codes that a scanner can read.

On the other hand, three-dimensional barcodes don’t use additional dimensions for data storage. Their “3D” aspect refers to the barcode’s physical structure, which is raised or etched onto a surface.

While “3D barcode” might suggest a more advanced technology, it’s essentially a two-dimensional with a unique physical feature.

With their efficient data storage and smartphone scanning capabilities, two-dimensional barcodes remain the preferred choice for most applications.

What is barcoding?

This involves the process of encoding information into a visual format that is readable by machines.
