What is a Data Matrix Code?

A Data Matrix code, also known simply as a Data Matrix, is a 2D barcode consisting of black squares arranged in a square or rectangular pattern on a white background. 

These barcodes can store large amounts of text, numbers, and binary data. Specifically, Data Matrix can encode up to 3,116 numeric characters, 2,335 alphanumeric characters, or even binary data up to 1,556 bytes. 

Data Matrix was invented in 1989 by engineers at International Data Matrix, Inc. The technology was later developed and popularized for broader applications, such as product tracking and tracing, and document management. 

How does Data Matrix Code Work?

Data Matrix codes work by using a binary code to represent data. The binary code is then converted into a series of black and white squares, which can be read and interpreted by a Data Matrix scanner.

The specific arrangement of black and white modules, along with the overall size of the code, determines the amount of data that can be stored.

Data Matrix VS. QR Code

Data matrices and QR codes are commonly used. Both are 2D barcodes used to store information. However, there are some significant differences between them.

1. Capacity: A Data Matrix can store more data in a smaller space compared to QR code.

2. Encoding:  A Data Matrix encodes data in a square or rectangular grid, while a QR code encodes data in a square grid.

3. Error Correction: QR Code typically has built-in error correction capabilities, whereas Data Matrix may require external error correction techniques for reliable data retrieval.

4. Application: Data Matrix is often used in industries like manufacturing and logistics, while QR Code is more widely used, including for consumer-oriented applications such as marketing and mobile payments.

What are Data Matrix Codes Used For?

Data Matrix codes are used in a variety of applications, including:

1. Product Tracking: Data Matrix codes are widely used in manufacturing and logistics for tracking products throughout the supply chain. They can store information such as serial numbers, batch numbers, and manufacturing dates.

2. Inventory Management: Data Matrix codes are utilized for inventory management in warehouses and retail environments. They help in accurately identifying and tracking inventory items.

3. Document Management: Data Matrix codes can be printed on documents to facilitate document management processes, such as sorting, filing, and retrieval.

How Do You Create a Data Matrix Code?

There are some tools to create a Data Matrix code. One way is to use a 2D Data Matrix generator. 

Step 1: Use the Data Matrix Code generator

You can choose a free online Data Matrix generator, which is easy to use and has rich customization functions.

Step 2: Enter Data

Enter the data you want to encode into the barcode. This can include text, numbers, etc.

Step 3: Create the Code

Click the "Create" button. The generator will create a Data Matrix code.

Step 4: Customize the Code

Many Data Matrix generators allow you to customize barcode properties such as width, height and color.

You can also customize text properties such as size, font, and color. Select the appropriate options based on what you want.

Step 5: Save and Download the Code

When the barcode has been generated, click the "Download" option to save it. The barcode is saved in PNG format by default, but you can choose another file type before downloading.

Step 6: Test and Verify the Code

After you have saved the code, you can test it to make sure it can be scanned. 

We recommend using the 2D Handheld Barcode Scanner for testing.

Someone may ask can mobile phones scan the Data Matrix?

Smartphones can generally read Data Matrix codes, but the ability depends on the specific model and software of the phone. 

Most modern smartphones have cameras capable of capturing the details required for Data Matrix codes. Third-party applications on these devices can then decode the information contained within the codes.

Overall, Data Matrix codes are diverse and strong barcodes that can be used in a variety of ways. They are simple to generate and may be read on a range of devices. Data Matrix codes are an effective solution for tracking items, assets, and documents.
