Data Matrix Barcodes

Data Matrix is a two-dimensional barcode symbology known for its high data capacity and compact size. Unlike linear barcodes, which encode data in one dimension, Data Matrix barcodes use a grid pattern of black and white modules to encode data in two dimensions, allowing for the storage of large amounts of information in a small space. Data Matrix barcodes can encode numeric, alphanumeric, binary, and even Unicode characters, making them suitable for a wide range of applications, including product tracking, document management, and inventory control. Their ability to withstand damage and distortion, coupled with their high data capacity and compatibility with various printing and scanning technologies, has made Data Matrix barcodes a popular choice for industries requiring robust and versatile data encoding solutions.

Normally, data size is from a few bytes up to 1,556 bytes. The length of the data depends on the symbol dimension used. To make sure the data can be read even when the pattern is slightly damaged, error correction codes are added which increase symbol strength. A Data Matrix symbol can store up to 2,335 alphanumeric characters. Here is a sample you can scan.

Barcode Data Matrix

Data Matrix symbols are rectangular in shape and usually square. As more data is added, modules are put together to allow for the data and error correction. Each module can be identified by the "L" shaped black line that runs down the left and across the bottom of each module. In the sample shown above, there are four modules. These "L" shaped sections are known as the "finder pattern". The top and right border of each module are made up of alternating light and dark blocks. Light blocks represent 0 (zero) and the dark blocks represent 1 (one). These are known as the "timing pattern". All of the blocks in the middle of each module make up the data and check codes. The entire pattern can range in size from 8x8 to 144x144 in size.
