Data Matrix is a two-dimensional matrix barcode, which encodes text or raw data in a pattern of black and white square modules. Usual data size is from a few bytes up to 2 kilobytes. By adding error correction codes (according to the ECC200 standard) the symbols can be read even if they are partially damaged.
Data Matrix is used for encoding large amounts of data, it is mainly used in Europe and in the United States. The dominating application areas are direct part marking and laser marking - both especially in the aerospace, electronic, and automotive industry. In addition Data Matrix is used for general logistic purposes, document management applications, postal services (digital stamps for the Deutsche Post, Premiumadress Service), and medical / health industry related applications (HIBC).
Starting with 2006/2007 the use of the Data Matrix barcode is also spreading in the area of mobile marketing, in such applications the Data Matrix barcode is also known under the name SemaCode. In a mobile marketing scenario a Data Matrix symbol is printed or displayed on products or marketing related materials (e.g. displays, magazines, and even web-pages). A user can now scan or decode this Data Matrix using a mobile phone with a built-in camera and suitable decoder software. After decoding the Data Matrix barcode symbol the user is forwarded to marketing or product related web-sites and blogs.
Data Matrix is a 2D barcode symbology with very high data density. Data Matrix symbols are printed in square or sometimes a rectangular pattern. Each dot of a Data Matrix symbol represents a bit. This is in contrast to linear bar-codes, where the information is encoded in the ratio of the bars or spaces to each other. Usually a black dot in a Data Matrix symbol is equivalent with the bit-value 1, but Data Matrix may also be printed white on black.
Data Matrix was developed by the company RVSI Acuity CiMatrix. This company was later acquired by Siemens Energy and Automation, Inc.
Data Matrix is also known under the name Semacode. As mentioned above this name is used for Data Matrix symbols when used for mobile marketing applications. See www.semacode.org, ECC200 Code, ECC 200.
Because of its technical advantages the GS1 organization considered the DataMatrix 2D barcode symbology for its system.
The so called GS1 or EAN Data Matrix is a standard DataMatrix symbol (ECC 200) with an internal GS1 identifier in the data structure (like the FNC1-Prefix in an GS1-128).
The use of Application Identifiers is supported, this is comparable to the linear barcode GS1-128/EAN-128 or GS1 DataBar Expanded, where a code word similar to FNC1 acts as a field separator.
Some selected standards, which utilize Data Matrix (ECC200) 2D bar code:
The following TEC-IT bar code software products support generation of Data Matrix bar codes:
2D Barcode Data Matrix with encoded URL (Mobile Marketing)
