QR Code VS. Data Matrix
Key Differences & Advantages

　　In the field of modern identification and information storage, QR Code and Data Matrix (DM) are two core 2D barcode technologies. To intuitively present their characteristic differences, we will compare them from three dimensions: appearance & structure, data capacity, and usage advantages.

QR Code

　　•Appearance & Structure

　　Square, with position markers in 3 corners.

　　•Data Capacity

　　Higher capacity (numeric: ~7k chars; binary: ~3k). Supports Kanji.

　　•Usage & Advantages

　　Better for consumer use (URLs, payments), versatile size/scannability.

Data Matrix

　　•Appearance & Structure

　　Square or rectangle, with L-shaped alignment pattern (no corner markers).

　　•Data Capacity

　　Smaller capacity (numeric: ~3k chars; binary: ~1.5k).

　　•Usage & Advantages

　　Ideal for small-item labeling (e.g., electronics, logistics), excels in tiny spaces.

　　In short, QR Code and Data Matrix each have strengths: QR Code is flexible and easy to use, while Data Matrix is compact and efficient, fitting consumer and industrial identification needs respectively.
