Overview

ISO/IEC 23941:2022 specifies the Rectangular Micro QR Code (rMQR) bar code symbology for automatic identification and data capture (AIDC). The standard defines how rMQR symbols are built, encoded, printed, and decoded - including symbology characteristics, data encoding methods, symbol formats, dimensional characteristics, error correction rules, reference decoding algorithms, printing quality requirements, and user-selectable application parameters. It targets compact, rectangular QR-style barcodes optimized for small-mark areas.

Key Topics

Symbology definition and structure: Detailed specification of symbol components such as finder patterns, timing patterns, alignment patterns, separators, encoding region and quiet zone.

Symbol versions and formats: Rules for symbol sizes and layout variants to support different data capacities.

Data encoding modes: Support and rules for Numeric, Alphanumeric, Byte, Kanji, Extended Channel Interpretation (ECI), FNC1 modes and mode-mixing strategies.

Error correction: Error detection and correction capacity, generator polynomials and procedures for generating/decoding error correction codewords.

Codeword placement & masking: Algorithms for placing codewords in the matrix and data mask patterns to optimize readability.

Reference decoding algorithm: A normative decode procedure allowing interoperable implementations and auto-discrimination.

Printing and marking requirements: Dimensional characteristics, human-readable interpretation, marking guidelines and print-quality parameters specific to rMQR.

Conformance & quality assurance: Requirements and process-control measurements to ensure reliable symbol creation and scanning.

Normative and informative annexes: Examples, byte mode character sets, print quality aspects, test procedures and user guidance.

Applications and Who Uses It

When to use rMQR: Ideal for marking on small items or constrained surfaces where traditional QR codes don’t fit - e.g., electronics components, medical devices, pharmaceuticals, jewelry, small-pack retail tags, and certain identity documents.

Primary users:

Barcode symbology designers and integrators
Software developers for barcode generators and decoders
Scanner and imaging hardware manufacturers
Label and direct-part-marking (DPM) printers
Quality assurance and process control teams
Regulatory/compliance officers specifying AIDC implementations

Benefits: Enables compact, high-reliability data encoding with standardized error correction and decoding rules to maintain interoperability across scanners and printing technologies.

Related Standards

Other QR and 2D barcode standards (for example, QR Code specifications such as ISO/IEC 18004)

Print-quality and symbol grading standards used in AIDC workflows (see ISO/IEC print-quality standards)

Implementation typically aligns rMQR usage with existing AIDC and supply-chain standards for interoperability.

Keywords: ISO/IEC 23941:2022, rMQR, Rectangular Micro QR Code, barcode symbology specification, automatic identification and data capture, error correction, encoding, decoding, printing quality.
