What is Data Matrix Barcode?

High-density 2D matrix barcode capable of encoding massive alphanumeric data in microscopic square areas. Defined under standard ISO/IEC 16022, Data Matrix is engineered for fast, reliable optical scanning across industrial and commercial environments.

SpecificationDetails
Standard SymbologyData Matrix (ISO/IEC 16022)
Character SetFull ASCII, ISO 8859-1 (extended ASCII), and binary data
Checksum AlgorithmReed-Solomon error correction (ECC 200)
Quiet Zone Margin1 module width on all 4 sides
Processing Mode100% Client-Side In-Browser (Zero Server Logs)

Key Advantages

  • Can be etched as small as 2mm × 2mm and still read accurately
  • ECC 200 error correction allows reading even if up to 30% of the code is damaged or scratched
  • Square and rectangular aspect ratio formats

📦 Common Use Cases

  • Direct Part Marking (DPM) on aerospace and automotive steel parts
  • Microchips, circuit boards, and smartphone electronics components
  • Pharmaceutical unit-dose medication serialization (FDA UDI / EU FMD)
  • GS1 2D barcode migration for retail checkout

Frequently Asked Questions

What is the difference between Data Matrix and QR Code?

Data Matrix has a smaller footprint for tiny items and requires only a 1-module quiet zone, making it ideal for micro-parts and healthcare serialization. QR Codes have finder patterns in three corners and are more popular for consumer mobile camera scanning.
