2D Barcodes

QR codes and Data Matrix — the next generation of product identification for retail.

What are 2D Barcodes?

2D (two-dimensional) barcodes store data in both horizontal and vertical patterns, allowing them to hold significantly more information than traditional 1D barcodes like UPC or EAN.

The two most common types used in retail and supply chain are QR Codes and GS1 Data Matrix.

1D vs 2D: The Difference

1D Barcode (UPC/EAN)

  • Holds only a product identifier (GTIN)
  • No batch, expiry, or serial data
  • Cannot link to digital content
  • Must be scanned in correct orientation
  • 50+ year old technology

2D Barcode (QR/Data Matrix)

  • Holds GTIN plus batch, expiry, serial
  • Can encode a web URL (Digital Link)
  • Connects to digital experiences
  • Omnidirectional scanning
  • Error correction built-in

Types of 2D Codes

QR Code

Best for consumer-facing applications. Easily scanned by smartphones. Ideal for packaging that consumers will interact with.

GS1 Data Matrix

Compact and robust. Preferred for small items, healthcare, and industrial applications. Can be printed very small.

Why We Focus on QR Codes

Consumer Device Compatibility

While both QR codes and Data Matrix are valid 2D barcode formats, most consumer smartphones cannot natively scan Data Matrix codes. QR codes, on the other hand, are universally supported by smartphone cameras — no special app required.

Since GTIN1 is designed to connect your products directly with consumers, we focus exclusively on QR codes. This ensures that anyone with a smartphone can scan your product packaging and instantly access product information, promotions, and support.

Data Matrix remains valuable for B2B applications like healthcare, logistics, and industrial settings where specialized scanners are standard. But for consumer engagement, QR codes are the clear choice.

Why Retail is Moving to 2D

By 2027, major retailers worldwide will accept 2D codes at point-of-sale. This transition, known as Sunrise 2027, is driven by:

  • Traceability — Track products by batch and serial for recalls and compliance
  • Consumer Engagement — Connect shoppers to product information, promotions, and support
  • Regulatory Requirements — Meet FSMA 204 and Digital Product Passport mandates
  • Efficiency — One code serves retail, logistics, and consumer needs
