DataMatrix is a two-dimensional barcode which can
store from 1 to about 2,000 characters. The symbol is square and can range from 0.001 inch
per side up to 14 inches per side. As an example of density, 500 numeric only characters
can be encoded in a 1-inch square using a 24-pin dot matrix printer. The sample shown
above encodes 20 ASCII characters.
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.
