Static and Dynamic QR Codes: What to Choose and When

A QR code is a modern tool for fast information transfer. It is a two-dimensional barcode that can store links, text, images, contact details, documents, and much more. QR codes are easily scanned using a smartphone camera, and the information instantly appears on the user’s screen, making it a great digital business card.

Compared to traditional linear barcodes, QR codes offer several advantages:

  • they can store significantly more data

  • they can be scanned from any angle

  • they are customizable in color and design

  • they are suitable for both print and digital formats

There are two main types of QR codes — static and dynamic. Each has its own features, benefits, and limitations. To choose the right type, it’s important to understand how each works and in what situations they are most effective.

Static QR Code

A static QR code contains embedded data such as a link, contact, or plain text. This data cannot be changed once the code has been generated.

Advantages of static QR codes:

  • free to generate

  • no internet connection required

  • ideal for permanent information

Disadvantages:

  • cannot be edited once created

  • large data sets make the code harder to read

  • no tracking or scan analytics

Use cases for static QR codes:

  • placing contact information on business cards

  • adding website or social media links to product packaging

  • printing on posters for limited-time promotions

  • sharing educational resources and links in books or manuals

  • providing access to events or specific areas (e.g., exhibitions or museums)

  • enabling cashless payments by linking to payment systems

  • offering interactive content like videos or quizzes in educational settings

Dynamic QR Code

A dynamic QR code contains a short redirect link that points to external data. This allows you to edit the destination content without changing the code itself.

Advantages of dynamic QR codes:

  • editable content at any time

  • stable structure regardless of data size

  • scan analytics: number of scans, location, device, time, and more

  • extra features like password protection, geofencing, and expiration settings

Disadvantages:

  • requires a subscription platform

  • can only be edited via an online service

When dynamic QR codes are useful:

  • in marketing campaigns where landing pages need to change frequently

  • for event management — issuing personalized access passes

  • in logistics and inventory tracking — each item has a unique code

  • for access control in offices, buildings, or production areas

  • for two-factor authentication in secure login systems

  • in virtual and augmented reality projects, such as immersive videos or digital content portals

Key Differences Between Static and Dynamic QR Codes

Data Storage:

  • Static codes store the actual data directly in the code. It cannot be changed after generation.

  • Dynamic codes store a redirect URL that can be updated as needed.

Flexibility:

  • Static codes are suitable for fixed, unchanging information.

  • Dynamic codes are ideal for content that may need to change over time.

Tracking and Analytics:

  • Static codes do not support any tracking.

  • Dynamic codes allow detailed analytics including time, location, and device.

Security:

  • Both types are safe if created with certified generators.

  • Dynamic codes offer extra features like password protection and geolocation restrictions.

If you need a simple, one-time, and free way to share data, choose a static QR code. If you plan to update content, analyze engagement, or use the code in marketing or tech projects, a dynamic QR code is the better option. Each type has its own role, and your choice depends on your specific goals.
