Dynamic vs Static QR Codes (What’s the Difference?)
QR codes look identical on paper. But how they behave after someone scans them depends entirely on whether they’re static or dynamic.
This difference matters more than most people realize - especially once codes are printed, shipped or installed in the real world.
Here’s a clear breakdown of how each type works, when to use them and where people get tripped up.
Static QR Codes - Fixed and Final
A static QR code contains the final information directly inside the code itself.
Most often, that’s a URL. But it could also be plain text, contact details or Wi-Fi credentials.
Once a static QR code is created, it cannot be changed. Ever.
What that means in practice
- The destination is embedded permanently.
- No redirects.
- No scan tracking.
- No dependency on any service.
- If the URL changes later, the QR code still points to the old one. The only fix is creating and printing a new code.
When static QR codes work best
- Business cards with fixed contact details.
- Permanent signage.
- Product documentation that won’t change.
- Wi-Fi access details.
The upside
- Free to generate.
- Works offline.
- No subscriptions.
- No third-party dependency.
The downside
- Zero flexibility.
- No analytics.
- Any mistake requires a reprint.
- Static QR codes are boring - and that’s their strength.
Dynamic QR Codes - Flexible but Dependent
A dynamic QR code works differently.
Instead of storing the final destination, the code stores a short redirect URL.
When someone scans it, their phone hits the redirect, the redirect forwards them to the current destination and because that redirect lives online, you can change where it points - even after the code is printed.
The physical QR code never changes. Only the destination does.
Why dynamic QR codes exist
- They solve one problem: change.
- They’re useful when content might change, campaigns rotate, links need emergency fixes or scan data matters.
Key capabilities
- Editable destinations - change the target URL anytime without reprinting.
- Scan analytics - track how often, when and roughly where scans happen.
- Simpler patterns - because they encode a short link, dynamic codes are often easier for cameras to read.
Where dynamic QR codes make sense
- Marketing campaigns with changing offers.
- Restaurant menus that rotate seasonally.
- Event signage.
- Flyers or posters reused over time.
- Physical placements you want to repurpose later.
The Hidden Trade-Offs of Dynamic QR Codes
Dynamic QR codes are powerful - but they are not free from risk.
Every dynamic QR introduces a dependency between the scan and your content.
What you’re relying on
- A redirect service staying online.
- That service not changing pricing.
- Your subscription not expiring.
- Internet connectivity at scan time.
If it fails
- If the redirect stops working, the QR code stops working, even though it’s printed perfectly.
- This is where many people get burned.
Static vs Dynamic - Quick Reality Check
Use this snapshot to decide at a glance.
| Question | Static | Dynamic |
|---|---|---|
| Can I change it later? | ❌ No | ✅ Yes |
| Does it track scans? | ❌ No | ✅ Yes |
| Needs internet to work? | ❌ No | ✅ Yes |
| Depends on a service? | ❌ No | ⚠️ Often |
| Best for | Permanent info | Change & measurement |
How to Choose (Without Overthinking It)
Lean on these quick filters before you commit to a type.
Pick static when
- The destination will never change.
- You don’t need analytics.
- You want maximum reliability.
- You’re printing once and forgetting about it.
Pick dynamic when
- Content might change.
- You want scan data.
- Reprinting would be costly.
- You need flexibility or safety nets.
A Simple Gut-Check Before You Print
Before committing to thousands of copies, ask:
Questions to ask
- Will this destination still exist in two years?
- What happens if the redirect service disappears?
- Do we actually need scan tracking - or just think we do?
- Who owns the domain between the scan and the page?
Final Takeaway
Static QR codes are permanent and dependable.
Dynamic QR codes are flexible and measurable - but introduce dependencies.
Neither is better by default. The mistake isn’t choosing the wrong type - it’s choosing without thinking about what happens after the code is printed.
- Have we stress-tested the destination if we go static?
- Do we control the redirect infrastructure if we go dynamic?
- Is everyone aligned on the trade-offs before we hit print?
