Differences Between Static and Dynamic QR Codes 

There are two main types of QR codes: static and dynamic. Understanding the difference will help you choose the right option for your goals. 

Static QR Codes 

What are they? 

Static QR codes contain fixed information encoded directly into the code. Once created, the data cannot be changed. 

Use cases: 

Links to websites, Wi-Fi passwords, contact info, plain text — anything that doesn’t need updating. 

Pros:

Free 

Perfect for permanent info 

Cons: 

Cannot be edited after creation 

Need to create a new code if data changes 

Dynamic QR Codes 

What are they? 

Dynamic QR codes contain a short URL or redirect service inside. When scanned, they direct users to the current destination, which can be updated anytime without generating a new code. 

Use cases: 

Marketing campaigns, coupons, promotions, scan tracking, or when flexibility is needed. 

Pros: 

Editable destination URL 

Track scan statistics (time, location, device) 

Additional features like password protection or expiration dates 

Cons: 

Usually requires a paid service 

Slightly more complex setup
