Figure 1. A DataMatrix code has three areas of interest: the Locator, the alternating black and white Boundary Cells and the Core Data area.

EXAMPLES:
Figure 2 shows sample images of the same data matrix code with missing information. By definition, the data matrix code can ecover up to 20% of missing information by using error correction built into the Solomon-Reed algorithm used to construct code.
