2D Codes (QR & DataMatrix) for Marking and Identification
QR and DataMatrix are two-dimensional codes used for marking products, assets, packaging, warehouse locations, and equipment.
Unlike traditional barcodes, 2D codes can store significantly more data and are used not only for internal tracking but also for traceability, product authentication, and linking to digital product passports or asset pages in enterprise systems.
QR and DataMatrix are part of a broader marking and identification system. Depending on the use case, they can be applied to labels, packaging, tags, nameplates, or other carriers.
What is a 2D code
A 2D code is a graphical code that stores information both horizontally and vertically, unlike linear barcodes. This allows QR and DataMatrix to contain more data within a compact space.
In practice, 2D codes are widely used as a universal tool to connect physical objects with digital systems.
QR codes in marking
QR codes are ideal for scenarios requiring fast scanning with smartphones or standard scanners. They are commonly used to link to product pages, instructions, service information, or digital product passports.
- product labeling;
- linking to digital product passports;
- equipment identification;
- asset tracking;
- marketing and promotional campaigns;
- product authenticity verification.
DataMatrix in marking
DataMatrix is widely used in manufacturing and logistics where space is limited and reliable automated scanning is required.
- serialized product marking;
- marking of small components;
- batch and serial number tracking;
- component identification;
- production traceability.
When to use QR, DataMatrix or RFID
| Task | Recommended solution |
|---|---|
| Customer access to product information | QR code |
| Marking small items | DataMatrix |
| Manual warehouse operations | QR / barcode |
| Mass reading without line-of-sight | RFID |
| Digital product passport | QR + Web Passport |
QR codes and digital product passports
One of the most перспективных applications of QR codes is linking each product to a unique digital product passport. Each item receives a unique code that leads to a dedicated web page containing product data, batch information, origin, instructions, warranty details, and authenticity verification.
This approach supports both internal operations and customer interaction, enabling service support, marketing campaigns, and brand protection.
Common mistakes in implementation
- code size too small;
- poor print quality;
- incorrect label material selection;
- lack of encoding standards;
- using identical codes instead of unique ones;
- no integration with enterprise systems;
- placing codes in areas prone to damage.
Vostok-IT approach
In automation projects, Vostok-IT treats QR and DataMatrix not as isolated label elements but as integral parts of a unified identification system.
We analyze the use case, environment, object type, scanning method, and data requirements. Based on this, we define the code format, select materials, choose printing equipment, and design data processing logic.
- business process analysis;
- code format selection;
- label and carrier selection;
- scanning validation;
- system integration;
- solution scaling.
