The Data Matrix Barcode is a 2D symbol used to encode larger amounts of data and commonly used in shipping, medical, and parts labeling applications. DataMatrix barcode can store from 1 to about 2,000 characters. DataMatrix barcode is perfect symbology that is able to encode both 128 ASCII characters (ANSI X3.4) and values 128 to 255 characters, known as extended ASCII (ISO 8859-1).
Data Matrix barcode symbol is made up of square modules either black or white. Usually Data Matrix symbols are black printed on white background, users can also print them as white upon black background. Data Matrix barcode is able to encode up to 1000 alpha-numeric characters. Therefore, Data Matrix is a good solution for encoding large quantities of data in one data matrix barcode symbol.
DataMatrix is being used to encode product and serial number information on electrical rating plates; to mark of surgical instruments in Japan to identify lenses, circuit boards, and other items during manufacturing. DataMatrix symbols require a 2-D scanner they cannot be read using an ordinary linear barcode scanner. A number of scanners are on the market using both laser and CCD camera technologies. DataMatrix symbols can be printed using most professional-grade thermal transfer label printers on the market.
Data Matrix symbols are made up of modules arranged within a perimeter finder and timing pattern. It can encode up to 3,116 characters from the entire ASCII character set (with extensions). The symbol consists of data regions which contain modules set out in a regular array. Large symbols contain several regions. Each data region is delimited by a finder pattern, and this is surrounded on all four sides by a quiet zone border (margin).
