Data Matrix is a 2D (matrix) barcode format available as open standard. Data Matrix was designed in 1989, and standardized by many organizations including NASA, US DoD and major industries such as electronics, pharmaceutical and postal marking. The information to be encoded can be text or raw data. Typical data size is from a few bytes up to 2 kilobytes. The length of the encoded data depends on the symbol dimension that is used. Error correction codes are added to increase symbol strength: even if they are partially damaged, they can still be read. A Datamatrix symbol can store up to 2,335 alphanumeric characters.
