About Qrivio Barcode
Qrivio Barcode is a free barcode generation and technical reference platform created for developers, businesses, retailers, warehouse teams, logistics professionals, and anyone working with machine-readable identification systems.
Our Purpose
Qrivio Barcode combines practical barcode generation tools with detailed technical resources explaining how barcode standards work, how identifiers are structured, and how machine-readable symbols should be prepared for real-world use.
The platform is designed to be more than a simple barcode generator. Its goal is to serve as a barcode reference and resource center covering identification, encoding, validation, printing, scanning, retail, warehouse, logistics, and related implementation topics.
Barcode Standards Covered
Qrivio Barcode provides technical guides covering commonly used retail, industrial, logistics, and 2D barcode technologies.
Retail & Product Identification
- EAN-13
- EAN-8
- UPC-A
- GTIN identification concepts
Industrial & Logistics
- Code 128
- Code 39
- ITF-14
- MSI Plessey
- Pharmacode
2D Technologies
The reference library also includes QR Code structure, error correction, module geometry, SVG printing workflows, and related 2D implementation topics.
Technical Content Approach
Technical guides are written to explain both the underlying barcode structure and the practical implementation requirements surrounding it.
| Topic | What We Cover |
|---|---|
| Encoding | Character sets, modules, bars, parity patterns, and symbol structure. |
| Validation | Check digits, checksums, identifier validation, and common data errors. |
| Printing | Physical dimensions, quiet zones, contrast, substrates, and scaling. |
| Scanning | Scanner behavior, camera systems, print quality, and failure diagnosis. |
| Implementation | Retail, warehouse, logistics, pharmaceutical, and production workflows. |

Accuracy and Standards
We aim to provide technically useful and accurate reference material. However, barcode requirements can vary by application, industry, jurisdiction, retailer, marketplace, printing process, and trading partner.
For commercial, regulated, or safety-critical implementations, always verify requirements against the current official standard, regulatory requirement, marketplace documentation, or trading-partner specification applicable to your project.
