Have you ever seen small, simple square patterns of black-and-white pixels on product packaging? These are two-dimensional barcodes or 2D codes, which can hold much of information. They have both horizontal and vertical dimensions.
These codes enable anything from managing inventories across many sites to verifying an item’s validity to scanning a good at check-out. Curious? Let’s investigate what they are and how they are used here!
What Are 2D Codes?
Advanced forms of conventional barcodes are two-dimensional codes. A typical barcode (1D code) stores data only horizontally; a 2D code stores data horizontally and vertically.
Unlike 1D barcodes, which require a precise scanning angle, 2D codes offer omnidirectional scanning, making them faster and easier to use. Additionally, their compact size and larger data capacity allow for more detailed information storage, including batch numbers, expiration dates, and product origins.
A 2D code can store much more data than a 1D barcode. For example, depending on the kind, a 2D code can hold up to 3,000 characters (or more) while, a 1D barcode can only retain roughly 30 characters.
Two-dimensional codes also come primarily in two types: stack and matrix. Here are the differences:
Stack type
Stack-type codes are numerous barcodes arranged vertically in a rectangle. It can be read with ordinary laser scanners but cannot accept more than ±10° movement.
Matrix type
Matrix-type codes, such as QR codes and DataMatrix codes, consist of a grid of squares or dots (called modules) arranged in patterns that a camera or reader can scan.

Key Features of 2D Codes
Because they can hold vast volumes of data in a small space, 2-dimensional codes have become ever more popular. If you’re curious about why these codes are such a game changer, here are some of their key features, broken down in simple terms:
Excellent Data Capacity
Usually, horizontal, conventional barcodes, which or 1D codes, can only store data in one direction. This limitation suggests, as was previously mentioned, that they could only save around 30 characters.
On the other hand, 2D code versions may contain far more information by storing data vertically and horizontally.
So, for usage like product information, URLs, and even contact information requiring more complex or comprehensive data, a 2D code (which can carry up to 3,000 characters) is significantly better.
Compact and Space-Efficient
Besides their great data capacity, 2-dimensional codes are highly compact and space-efficient. Their design allows them to be produced in relatively tiny regions.
Given the exact data count, a 2D code may be as short as 1/30th the size of a conventional barcode. Industries where space is constrained can especially benefit from this space-saving capability.
Error Correction and Data Restoration
One of the standout features is the error correction capabilities. This implies that the code may be accessed and the data retrieved even if part of it is smeared or corrupted.
This is achieved using mathematical error correction algorithms, such as Reed-Solomon. For instance, a QR code may still be scanned correctly even if up to some percent of it is damaged.
Versatility in Reading Directions
The adaptability of a 2D code in interpreting directions adds even another unique quality. Thanks to their matrix-style design, these codes may be read from almost any direction whereas conventional barcodes must be scanned from a designated angle.
Image or camera equipment can rapidly decipher the information whether you scan it from the side, upside down, or at an angle. This adaptability will definitely help streamline the scanning process.
Applications of 2D Codes
These characteristics make 2-dimensional codes flexible and enable a broad spectrum of advanced uses. These are some instances of applications for which these codes find use:
Retail and E-Commerce
A single 2D code on a product labeling can contain a product’s entire journey from manufacture to retail, helping businesses manage recalls or track expiration dates, used for inventory management, promotional content, and more.
Healthcare and Pharmaceuticals
2D codes are tracked in the medical field for medicines, medical equipment, and patient records (medication traceability). They help ensure the proper medications, so hospitals and clinics can improve patient safety and reduce the risk of errors.
Logistics and Supply Chains
Next, these codes are essential for monitoring products throughout the manufacturing process and the supply chain. Every object might have a unique identity that allows companies to monitor it from production to distribution.
Identification and Security
Additionally, these codes play a crucial role in authentication and anti-counterfeiting, allowing businesses and consumers to verify the authenticity of products. The codes identify not just products but also passports, visas, ID cards, and more.
2D Code Printing Technologies
The practical function of 2-dimensional codes depends on their print quality. Different printing technologies apply these codes to products, packaging, and labels. These include:
Inkjet Printing
Inkjet printing is one of the most widely used methods. Whether a QR code or a Data Matrix, it works by spraying tiny ink droplets onto a surface to create the required pattern. It is flexible and can print on a wide variety of materials.
Laser Marking
On the other hand, laser marking uses laser beams to etch or engrave the 2D code directly onto a surface. This durable method ensures the code will remain readable even in challenging situations or harsh environments.
Benefits of Using 2D Codes
Depending on their traits and flexible use, the excellent use of these codes benefits consumers and businesses equally in many different ways:
The Future of 2D Codes
As businesses continue to digitize, 2D codes are evolving to include new functionalities, such as dynamic codes that update data in real time. Emerging trends include the integration of 2D codes with blockchain technology for enhanced traceability and security, as well as the use of augmented reality (AR) to deliver interactive experiences via scanned codes.
Increased Efficiency
These codes simplify procedures by allowing quick access to comprehensive information. This reduces the chance of human error, accelerates processes like inventory management and product tracking, and enhances supply chain efficiency.
Enhanced Data Storage
With their enormous data capacity, these codes help businesses preserve more data in a smaller area, improving traceability and monitoring of goods in industries with limited space or where specific product information is required.
Cost Savings
Integrating these codes into packaging and product labels helps businesses reduce mislabeling, product recalls, and associated expenses on inefficient inventory management.
