On the other hand, Datamatrix codes have an EC of 33%.
Error correction is the ability to restore data when the code is damaged. Another significant difference between the two is Error Correction levels.In Datamatrix codes, more space is available for data encoding, and they’re more compact than QR codes.Datamatrix codes can only hold 2335 alphanumeric characters, while QR codes can store up to 4296 alphanumeric characters.On the other hand, Datamatrix code can be as small as 10 × 10 modules. The smallest possible version of QR code comprises 21 × 21 modules.When more data needs to be encoded, both these barcodes add more modules.īoth these codes look similar, and you can’t find the difference with the naked eye.Both these codes help in data detection and decoding.A quiet zone is an empty white border around the code. Both these codes have some similarities and differences. What Are the Similarities and Differences between QR and Datamatrix Codes?īoth of these are 2D codes. If you’re already using QR code readers, you can try them because some QR readers also have the ability to read Datamatrix codes. In the industrial sector, some devices are used for reading these codes, such as:įor consumer usage, you can find some mobile devices that can read these Datamatrix codes. You can mark these codes on parts in three ways, such as:
How to Perform Direct Marking on Components / Parts? Lower contrast is enough for sufficient scan readability.They can be read in any position from 0 to 360-degree.They have a high fault tolerance of up to 33%.Some advantages of using Datamatrix codes are: They can be used in personal computers, tablets, mobile phones, and consumer electronics.These codes are better than QR codes, but they’re used in the warehouse rather than in consumer applications.They are good for asset tracking and data-driven applications.For the first time, NASA used Datamatrix codes in 1980 when they engraved these codes into parts of space rockets.As mentioned earlier, they can store a large amount of data in a small space, so they’re popular in pharmaceuticals industries.They have become popular for marking small items, such as electronic accessories or components.Some common applications of Datamatrix codes are given below: Moreover, they help in quality control, identification, and traceability. Therefore, they’re used in industrial sectors. They allow direct marking on components and parts. Over the past few years, Datamatrix codes have become popular.
