Data Matrix & QR Code: Are They Different?

Picture this: you’re at a grocery store and scan a square code to get a digital coupon. Meanwhile, another square code in a factory is scanned to verify a product’s authenticity.

While they may seem similar at first glance, these two small squares are distinct in their capabilities and applications. The former is a QR code, while the latter is a data matrix. They are potent tools that hold rich information.

Let Us First Introduce You to Matrix Code and Barcode and Their Differences

Barcodes are the lines and spaces you often see on product packaging. They’re one-dimensional, meaning they only store information in a horizontal line. This limits the amount of data they can hold.

On the other hand, matrix codes are two-dimensional. They store information horizontally and vertically, allowing them to hold more data. Because of this, they’re used in more complex applications like tracking medical equipment or airplane parts.

Now, What is a Data Matrix and Its Functions?

A data matrix code is a two-dimensional matrix barcode that stores information in a small space. This makes it incredibly useful for industries that need to encode large amounts of data quickly and efficiently.

For example, this code is used in healthcare to label and track medical equipment. In manufacturing, they’re used to mark parts for quality control. The code consists of black and white squares and can store up to 2,335 alphanumeric characters.

Structure of Data Matrix

This code is a 2D matrix code developed by ID Matrix in 1987 and later standardized by AIMI and ISO/IEC. The structure is quite specific. It uses an L-shaped frame called the alignment pattern and dotted lines known as the clock pattern to help scanners determine the code’s position. When the code has more than 24 x 24 modules, it’s divided into blocks to prevent distortion.

Specifications of Data Matrix

The specifications of data matrix codes come in two main types: square and rectangular. The square type has sizes ranging from 10 x 10 modules to a maximum of 144 x 144 modules. It can store up to 3116 numeric characters or 2335 alphanumeric characters.

On the other hand, the rectangular type has a minimum size of 8 x 16 modules and can go up to 16 x 48 modules. This type can hold up to 98 numeric characters or 72 alphanumeric characters.

Types of Data Matrix Code and Its Examples

Two types of data matrix codes exist: ECC 200 and ECC 000-140. Below is the explanation of each:

1. ECC 200

ECC 200 is the more modern and widely used version. It’s known for its advanced error correction capabilities, which means the information can still be retrieved even if the code gets partially damaged.

This makes ECC 200 highly reliable and a popular choice in sectors like healthcare, where it’s used for patient IDs. It’s also prevalent in manufacturing for labeling part numbers and logistics tracking shipments.

2. ECC 000-140

This type is an older version and is less commonly used today. It doesn’t offer the same error correction level as ECC 200, making it less ideal for critical applications.

How to Scan Data Matrix

Scanning this code is simple, but using the right equipment for accurate decoding is crucial. Here are the steps:

1. Choose the Right Scanner

Use a 2D barcode scanner or a smartphone with a specialized scanning app. These devices are equipped to read the complex patterns of this code.

2. Position the Scanner

Hold the scanner or smartphone at a reasonable distance from the code. Make sure the entire code fits within the scanning area.

3. Initiate the Scan

Most scanners will automatically start scanning once the code is in focus. You might need to tap a button for smartphone apps to begin the scan.

4. Decode and Utilize

Once scanned, the device will decode the information stored in the code. This could be a URL, text, or other data, which can be used for various applications like inventory management or patient identification.

Next, What is a QR Code Actually?

A QR code (Quick Response code) is another type of 2D matrix barcode. It was initially designed in 1994 for tracking automotive parts but has since found applications in a wide range of industries.

QR codes are often used in consumer-focused applications. They’re commonly found in advertising materials, product packaging, and websites. When scanned with a smartphone, they can direct you to a website, offer a coupon, or provide more information about a product.

Several Functions of QR Code

QR codes are incredibly versatile and can be used for many purposes. What are they? Below is the list:

1. Marketing and Advertising

QR codes are often used in marketing materials to direct consumers to a website, video, or other digital content.

2. Product Information

QR codes can provide consumers with additional information on product packaging, such as user manuals or ingredient lists.

3. Event Ticketing

QR codes are commonly used for event tickets, making entry more streamlined and efficient.

4. Payments and Transactions

Some payment systems use QR codes to facilitate quick and secure user transactions.

5. Location Services

QR codes can pinpoint a location on a map, which is useful in tourism and real estate.

Specifications of QR Code

QR codes are square and have black modules arranged on a white background. They can store various data types, including numeric, alphanumeric, binary, and special characters.

The storage capacity varies depending on the version of the QR code, with the smallest version (Version 1) storing up to 25 alphanumeric characters and the largest (Version 40) storing up to 3,000. QR codes also offer error correction levels, ranging from Low (L) to High (H), allowing data recovery even if the code is partially damaged.

Types of QR Code

QR codes consist of two main categories. Here’s the explanation.

• Static QR Code

This code is generated once for specific campaigns and has an unchangeable URL. It’s used for preset emails, sharing contacts, and directing users to websites.

• Dynamic QR Code

These codes can be updated post-creation and handle complex uses like asset tracking and inventory. They’re also good for interactive education, brand promotion, and virtual property tours.

Key Differences between Data Matrix and QR Code (A Table)

Let’s look at the following table to grasp the key differences further.

Feature	Data Matrix Code	QR Code
Industry Use	Healthcare, Aerospace, Manufacturing	Consumer-Facing, Retail
Damage Tolerance	Up to 50%	Up to 30%
Storage Capacity	Up to 2,335 alphanumeric characters	Up to 4,296 alphanumeric characters
Compactness	More compact, ideal for small spaces	Less compact, requires more space
Error Correction	Automatically determined	Selectable levels (7%-30%)

Which One Suits You? Data Matrix or QR Code?

If your industry demands high reliability, robustness, and you have limited space for coding, data matrix is likely the better option. It’s commonly used in healthcare, aerospace, and manufacturing sectors.

On the other hand, if your focus is more on consumer engagement and you need a code that’s easy to scan with a smartphone, QR codes are the way to go. They’re often used in retail, advertising, and event ticketing.

In short, your choice should align with your business needs, whether high data integrity or consumer accessibility.
