Data Matrix
A 2D matrix barcode that stores data in a square or rectangular pattern of black and white cells, capable of encoding up to 2,335 alphanumeric characters. Its Reed-Solomon error correction allows recovery from up to 30% symbol damage, making it the standard for direct part marking on aerospace and medical components.
