QR codes can store all kinds of information. Some are simple and fixed. Others can be edited and tracked after they’ve been printed. These are the two main types of QR codes: static and dynamic.
Each serves a different purpose. Understanding the difference helps you decide which one to use.
What Is a Static QR Code?
A static QR code holds information directly inside the code. Once it’s created, the data cannot be changed. If you encode a website URL, for example, the QR code will always go to that exact address.
These are best for short-term uses or when the content never changes. You might use one on a printed flyer that links to a permanent webpage. Static QR codes don’t require an internet connection to be created, and they never expire.
However, you can’t track how often they’ve been scanned or edit the link later. If you need to update the destination, you’ll need to generate and print a new QR code.
What Is a Dynamic QR Code?
A dynamic QR code points to a short redirect link instead of storing the full information in the code. This link sends the user to your content. Because the redirect can be updated behind the scenes, the destination can change without altering the printed code.
You can also see scan data. Dynamic QR codes often include tracking tools that show how many times the code was used, where, and when.
These are useful for marketing campaigns, business cards, signs, and menus—any situation where the destination might change or analytics are important.
Dynamic QR codes typically require a backend system or paid service to manage redirection and tracking.
When to Use Each One
- Use a static QR code when you’re sharing fixed content like a PDF, personal website, or email address.
- Use a dynamic QR code when you need flexibility, tracking, or expect to update the link in the future.
Summary
Both types of QR codes are useful. The best choice depends on how you plan to use it. Static codes are simple and permanent. Dynamic codes are flexible and trackable.
