ISO/IEC 23941:2022 is an international standard that defines the Rectangular Micro QR (rMQR) Code symbology, a space-efficient, rectangular variant of the QR Code. It is designed for narrow or elongated printing areas where a square QR code cannot fit, such as slim labels, cables, and small components. rMQR supports a range of versions from R7x43 through R17x139, letting the symbol's height and width be tuned to the available space, and offers error-correction levels M and H for reliable reading. By extending QR-style encoding into rectangular formats, ISO/IEC 23941:2022 addresses use cases that square symbologies handle poorly while remaining part of the broader QR Code family. It serves as the authoritative reference for generating and decoding rMQR codes in industrial and product-marking applications.
