2D Barcode vs QR Code: What’s the Difference in 2024?

2 minutes

In this 2D barcode vs QR code article, we will explore the unique characteristics of QR codes and 2D barcodes and uncover the key differences between the two.

2D Barcode vs QR Code

What is a 2D Barcode?

A 2D barcode is an image containing data that can be scanned by either barcode readers or smartphones. It is widely used in product packaging, ID cards, and inventory management.

Unique Characteristics of 2D Barcodes:

Data Density: 2D barcodes can store hundreds to thousands of characters of data, surpassing the 10-20 character limit of 1D barcodes. They are ideal for encoding complex data such as URLs, contact information, or inventory details.

Versatility: They can encode different types of data formats, including text, numbers, and binary data, making them suitable for a wide range of applications.

Error Correction: 2D barcodes often incorporate error correction algorithms, allowing for the retrieval of accurate data even if parts of the code are damaged or obscured.

Compact Size: Despite their ability to hold vast amounts of data, 2D barcodes are relatively compact, conserving space on printed materials.

Difference between a 2D barcode and QR code

What is a QR Code?

A Quick Response (QR) code is a type of 2D barcode that can be quickly scanned by smartphones and barcode readers to access information. It is often used for various purposes such as marketing, advertising, ticketing, and contactless payments.

Unique Characteristics of QR Codes:

High-Speed Scanning: QR codes are designed for rapid scanning, and they can be scanned from any angle, making them user-friendly and efficient.

Standardization: QR codes adhere to international standards, ensuring compatibility across different devices, applications, and platforms.

Error Correction: QR codes incorporate sophisticated error correction techniques, enhancing their reliability and accuracy in data retrieval.

Customization: QR codes can be customized with different colors and designs while still retaining their scannability, allowing for branding and creative applications.

QR Code vs 2D Barcode

QR Code vs 2D Barcode: What’s the Difference?

2D barcodes and QR codes are both two-dimensional data encoding technologies, but they have distinct characteristics. We will explore their differences below:


2D Barcode: The design of a 2D barcode can vary widely, with rectangular or square shapes being common. They are often composed of a pattern of dots, squares, or other geometric shapes that encode data.

QR Code: QR codes have a distinct square design, characterized by a grid of black squares on a white background. This unique design is instantly recognizable and allows for quick scanning.

Data Capacity 

2D Barcode: 2D barcodes offer a good data capacity but are generally limited compared to QR codes. They can store a moderate amount of information, suitable for applications like product labeling and ID cards.

QR Code: QR codes excel in data capacity. They can store a significant amount of data, including URLs, contact information, and more extensive text. This makes QR codes highly versatile for various applications.

Error Correction 

2D Barcode: 2D barcodes may or may not include error correction, depending on the specific encoding format used. Error correction capabilities can vary, impacting the reliability of data retrieval.

QR Code: QR codes are known for their robust error correction. They can still be scanned accurately, even if part of the code is damaged or obscured. This feature enhances their reliability, especially in real-world scanning conditions.


2D Barcode: Compatibility with 2D barcodes can vary depending on the encoding format. Some formats may require specialized barcode readers or software, limiting their compatibility with certain devices and systems.

QR Code: QR codes adhere to international standards, ensuring compatibility across a wide range of devices, apps, and platforms. This standardized approach makes QR codes highly versatile and widely supported.

Use Cases 

2D Barcode: 2D barcodes find extensive use in inventory management, asset tracking, and document control within industries like manufacturing, logistics, and healthcare.

QR Code: QR codes have diverse applications, including marketing, advertising, ticketing, mobile payments, and contactless information sharing. They are often seen in consumer-facing scenarios.


2D Barcode: While some customization options exist for 2D barcodes, they are primarily used for functional purposes. Customization options may be limited compared to QR codes.

QR Code: QR codes offer extensive customization possibilities. Businesses can brand them with logos, colors, and design elements while retaining their scannability. This makes QR codes ideal for marketing and branding efforts.

We hope that our 2D Barcode vs QR code article has now left you with a better understanding of the key differences between 2D barcodes and QR codes.
