Data Matrix vs. QR Code: When To Use Each | InkJet, Inc.

Data matrix codes and QR codes are quite cross-functional, and they have a similar look in most cases as well. This can lead some to believe that they are completely interchangeable, but this isn’t necessarily the case. While there is heavy overlap in the possible use cases of data matrix vs QR codes, their unique features make each lend themselves better to certain applications.

Let’s start with what is similar. Both code types are 2D codes, meaning they are able to represent alphanumeric data aligned vertically and horizontally, as opposed to barcodes which can only be read horizontally. This allows for increased data storage within each code when compared to barcodes. They both leverage finder patterns, or markings that are the same on every code to help scan tools identify their position and read the code. Now, what is different?

Data Matrix vs QR Codes

Data Matrix codes and QR codes differ in aesthetics, functionality, readability, data storage potential, and sometimes even shape.

	QR Code	Data Matrix Code
Storage Capacity (# Only)	7,089	3,116
Storage Capacity (Alphanumeric)	4,296	2,335
Storage Capacity (Binary)	2,953	1,556
Storage Capacity (Kanji/Kanja Characters)	1,817	N/A
Size Range	21x21 cells - 177x177 cells	10x10 cells - 144x144 cells
Error Correction Level (ECL)	7%, 15%, 25%, or 30% depending on print setting (higher ECL = lower storage cap)	Max of 30%
Readability	2D barcode scanners, smartphones, other camera-enabled devices with QR scanning software	Data matrix-specific 2D code scanners

Storage Capacity

The storage capacity of QR codes is larger, but so is their minimum size. So, while data matrix codes are seemingly at a disadvantage when it comes to storage, they can outperform QR codes in smaller form factors, and some footprints are so small that they are only compatible with data matrix codes. Another worthwhile note is that only QR codes can store Kanji/Kanja characters.

Size Range

Size range refers to the number of readable cells that each code can display. It is worth noting that data matrix codes are incremented in 2-cell increments, whereas QR codes are in 4-cell increments. This is because QR codes are always squares, whereas data matrix codes can be made rectangular. Following the trend set above, QR codes have a higher maximum and minimum size.

Error Correction Level (ECL)

ECL is the percentage of the code that can be damaged before it can no longer be read. Both QR codes and data matrix codes have a maximum ECL of 30%, but how that level is determined differs.

Data matrix codes have an ECL that is automatically determined by the size of the code and the amount of storage capacity headroom remaining after all data is stored. QR codes’ ECL is manually selected, and by manually selecting a higher ECL, the storage capacity of the code is lowered. This means both codes have ECLs that can be tweaked manually, but data matrix codes require the user to influence the ECL indirectly by increasing the code size to create headroom between their max capacity and the amount of data stored.

Readability

The primary reason why consumers don’t tend to know much about data matrix codes is that they can only be read by specific 2D barcode scanners. QR codes can be read by any camera with access to the right software, making them more compatible with consumer-facing applications.

Data Matrix and QR Code Applications

The above differences in functionality and form factor provide distinct advantages for each code type in certain applications. Below are some of the common applications for each code type, and why they are used for them.

Data Matrix Code Applications

The primary advantage of data matrix codes are their size, and their ability to store more information at smaller form factors. This makes them the go-to code for smaller products like individual electronic parts, as well as industries where traceability is a concern like automotive and aerospace parts. They are also the only 2D codes approved by GS1 for healthcare/medical marking applications.

QR Code

Since QR codes are larger and can store more data, they are typically used in applications that require this capacity. They are also the only option for consumer-facing applications, which is why they are used for things like user instructions, recipes on food items, social media sharing, website links, and marketing promotions.
