Dynamic QR codes are an advanced QR code technology where the content can be changed after scanning, and scan analytics can be tracked. Unlike traditional (static) QR codes, the content they redirect to can be updated even after the QR code is printed. This feature both saves on printing costs and provides flexibility for your marketing campaigns.
This guide will help you understand what Dynamic QR Codes are, how they work, how to create them, and what to consider before purchasing.
What Is a Dynamic QR Code?
Dynamic QR codes are advanced 2D barcodes that direct users to a link, custom landing page, or digital content. Unlike traditional (static) QR codes, the content of these codes can be changed afterward, and every scan can be tracked through the system.
This type of QR code works through short URLs. Data is not stored directly inside the QR code, but on the server. As a result, the QR code contains fewer modules (making it smaller and easier to scan), and the content can be updated whenever needed.
In addition to vCard, PDF, URL, and Menu QR codes, dynamic codes also support large images, videos, and any other media types containing links.
Features available to dynamic QR code users:
- Unlimited content updates after the QR code is generated.
- QR code can be scaled down to as small as 1 cm and remain readable.
- Easy sharing by naming each QR code.
- Detailed scan count and analytics.
- Phone support available.
- Multi-currency payment options.
- QR code duplication for fast bulk creation.
- Buy any quantity you need with no obligation to renew at term end.
How Does a Dynamic QR Code Work?
Dynamic QR codes don’t embed content directly inside the code. Instead, they redirect through a short URL to a server. This structure allows the content to be changed later, and scan data can be analyzed in detail.
📌 Step-by-Step Operation:
- The QR code is scanned. The user scans the code with a phone camera or QR reader app.
- The browser is redirected to a short URL. The dynamic QR code first sends the user to a redirect server such as qrcodeg.com.
- The server checks the assigned content. The current link, file, or digital business card associated with the code is determined.
- The user is redirected to the current target. Whatever the content (PDF, video, website, etc.), the user always reaches the latest version.
- The scan is logged in the analytics system. Scan time, device type, IP information, and location data (if available) are recorded.
🚀 What Are the Advantages?
The user experience can be optimized without interruption.
Content can be updated infinitely without changing the code.
Every scan is recorded and can be analyzed.
Target content can be changed dynamically based on campaign periods.
