rMQR code
rMQR is a rectangular QR variant standardised in ISO/IEC 23941 (2022). It carries more data than Micro QR in a long, thin footprint, which suits cable labels, pipes, cylindrical parts and shelf edges.

Why rectangular
A square code wastes space on a narrow surface. rMQR ranges from 7 to 17 modules high and 27 to 139 modules wide, holding up to 361 alphanumeric characters or 219 bytes.
Where it wins
Cable and wire labels, medical vials, pharmaceutical blister packs, shelf-edge tickets, pipe marking, any surface with plenty of length and almost no height.
Support
Newer than standard QR and much less widely implemented. Modern industrial imagers support it; phone cameras largely do not. Treat it as an industrial format and confirm the reading hardware before committing.
