QR code vs Data Matrix code – What is the difference?
Information storage is nowadays essential in order to communicate easily with employees throughout the supply chain or even with customers. QR codes and datamatrix codes have been developed to enable efficient and simple data transmission. Keep reading this article if you want to find out what the difference between a QR code and a Data Matrix code is.

Advantages of QR codes and Data Matrix codes
QR code and Data Matrix are two-dimensional barcodes (2D). It means that the information is stored horizontally and vertically in the square that represents it using pixels. This type of technology can therefore contain a lot of information!
In addition, the structure of these codes allows them to be read in any direction, which is extremely practical.
Finally, a corrector is associated with this technology, which means that even damaged, the code can be read, making it durable over time.
Structure differences between QR and Data Matrix codes
The main difference concerns the code structure and more particularly the recognition points. QR codes consist of 4 white & black squares in each corner, although the last one is less visible. They can contain 7089 numeric characters or 4296 alphanumeric characters. This code can store many types of information and result in different actions. It is easy to read through a smartphone, a barcode scanner, etc.
Data Matrix codes use an alternative structure for their recognition points. There is an L on the left and at the bottom of the square. They can contain up to 2335 alphanumeric characters, which is less than the QR code. However, their format is very small. They can be 10×10 pixels against 21×21 pixels for the QR code. This explains why Data Matrix codes are often preferred for labeling small items and reducing consumables use (ink, labels, etc.).
QR codes and Data Matrix codes – Differences in use
The QR code has been widely used following the Covid-19 crisis in many aspects of consumers’ daily lives. The Data Matrix code, on the other hand, remains less known. It is often used in industry as it takes up less space to store information. In addition, it is more secure! It is therefore particularly useful for ensuring product traceability throughout the supply chain.
ISO standards for QR and Data Matrix codes
The QR code and the Data Matrix code both apply the ISO standard:
- QR code: ISO/IEC 18004.
- Data Matrix: ISO/IEC 16022.
However, only the Data Matrix code is approved by the GS1 for healthcare, automotive and aerospace products.
