Cable tags and narrow component edges need a QR-family code that fits a long, thin aspect ratio -- exactly what rMQR was designed for.
Preconfigured for narrow labels
This experience fixes the symbol to the "R13x99" rectangular version instead of the primary's "R17x139", for tighter width constraints.
Example data
The generator is seeded with a bwip-js-verified valid value you can adapt with your own short identifier.
Workflow
Enter your identifier, choose a rectangular version matching your label's aspect ratio, then export SVG.
Job-specific settings
Pick the narrowest version that still fits your data to maximize label real estate savings over square QR Code.
Common mistakes
Assuming rMQR has identical capacity to square QR Code at the same module count is a common misunderstanding; check the fixed version's actual capacity.
Standard
rMQR is defined by ISO/IEC 23941.
