What Are 2D Codes and Why Do They Exist?

2D codes (two-dimensional barcodes) are graphic symbols that store data both horizontally and vertically, unlike traditional 1D barcodes that hold information in a single line.

This structure allows 2D codes to contain much more information—up to around 3,000 characters, compared to about 30 in most 1D codes.

Key advantages:

• Higher data capacity and damage resistance – even if part of the code is scratched or damaged, it can still be read thanks to built-in error correction.
• Flexible readability – they can be scanned from different angles and, in the case of QR codes, by smartphones without requiring a dedicated app.
• Traceability and engagement – beyond supply chain transparency, 2D codes can also connect consumers directly to digital content like websites, instructions, and promotions, enriching the overall customer experience.

With growing regulatory requirements and the demand for more transparency, 2D codes are not just a technical upgrade — they are strategic tools that help ensure compliance, improve traceability, and strengthen consumer connections.
