2-D Data Code Matrices for Marking Products
A data matrix code is a 2-dimensional (2-D) array of
white and black squares that represent binary values. Depending on the
size of the array, a data matrix can contain encoded alphanumeric
information from a few bytes to kilobytes. The information contained
within the data matrix can therefore be used to identify products, to
trace products, and acts as a strong anti-counterfeit measure.
The data matrix can be attached, placed or marked on the products by various means such as industrial ink-jet printing, electrolytic chemical etching and laser marking.
