Data Matrix (also 2D barcodes, 2D DPM - Direct Part Mark) are becoming common on printed media such as labels and letters. The code can be read quickly by a scanner which allows the media to be tracked, for example when a parcel has been dispatched to the recipient.

After creation of the Data Matrix code, the code is usually verified using specialist camera equipment and software. This verification ensures the code conforms to the relevant standards, and ensures it will be readable for the lifetime of the component. After the component enters service, the Data Matrix code can then be read by a reader camera, which decodes the Data Matrix data which can then be used for a number of purposes, such as movement tracking or inventory stock checks.

Data Matrix was invented by RVSI/Acuity CiMatrix, who was acquired by Siemens AG in October, 2005. Datamatrix is covered today by an ISO standard, ISO/IEC16022—International Symbology Specification, Data Matrix, and is in the public domain, which means it can be used free of any licensing or royalties.
