Data Matrix is a compact 2D barcode that packs data into a small square, even at a few millimetres. That makes it the go-to for electronics, tools and medical items.
Why it is used
It stays readable when small and tolerates damage thanks to built-in error correction, so it survives rough handling.
Common applications
Marking circuit boards, surgical instruments, pharmaceutical packs and small components where a QR code would be too large.
Printing
Ensure sharp edges and good contrast; tiny codes are unforgiving of blur, so print at the highest practical resolution.
