About Data Matrix
Data Matrix packs text into a grid that stays readable at a few millimetres across. Built-in error correction lets it survive scratches and partial damage.
Industrial scanners and most 2D scanner apps read it. Most phone camera apps look only for QR codes, so for anything the public scans, use a QR code.
