Data Matrix

Data Matrix is a compact 2D barcode that packs up to 2,335 characters into a very small square or rectangle, often just a few millimetres wide.

How it works

An L-shaped solid finder border and a dotted timing pattern let scanners locate and grid the modules, while strong error correction allows reliable reads on tiny or laser-etched marks.

Where it's used

The standard for marking small items — electronic components, surgical instruments and medical devices (direct part marking), and pharmaceutical unit packs.
