Dynamic QR Codes: What They Are, Why Use Them & How to Create One
Dynamic QR codes let you update your destination URL after printing, track every scan with real-time analytics, and run A/B tests — all without changing the printed code.
What Is a Dynamic QR Code?
A dynamic QR code is a type of QR code that stores a short redirect URL in the code pattern — not the final destination URL. When a smartphone camera scans the code, the device follows the redirect URL to a server, which then instantly forwards the user to whatever destination URL you have currently configured. You can change that destination at any time without reprinting or replacing the physical QR code.
This is the fundamental difference between dynamic and static QR codes. A static QR code encodes the destination directly into the black-and-white pattern. Once printed, it is permanently fixed. To change where a static QR code points, you would need to generate a completely new QR code and reprint it.
Dynamic QR codes were specifically designed to solve this limitation. For businesses printing thousands of menus, product labels, or marketing materials, the ability to update a destination without a reprint is enormously valuable — and the built-in analytics make every scan measurable.
💡 Key insight: The physical QR code pattern never changes — only the server-side redirect destination changes. This is why a dynamic QR code printed in 2023 can still work perfectly in 2026, even if the destination URL has been updated dozens of times.

How Does a Dynamic QR Code Work Technically?
The mechanics are straightforward. When you create a dynamic QR code with ScansTrack, the system:
- Assigns a unique short redirect URL to your QR code (e.g.,
sct.link/a1b2c) - Encodes that short redirect URL into the QR code pattern
- Stores your actual destination URL in the ScansTrack database
- When scanned, routes the user through the redirect and logs scan data in real time
Because the QR code pattern only encodes the short redirect URL, it has far fewer data points to encode — resulting in a cleaner, lower-density pattern that is easier to scan, even at smaller sizes or with poor print quality.
Key Benefits of Dynamic QR Codes
Edit the Destination Anytime
Printed a QR code on 5,000 flyers before your URL changed? No problem. Update the destination in your dashboard in seconds and all existing codes instantly point to the new URL.
Real-Time Scan Analytics
Every scan is recorded: device type, OS, browser, country, city, date, and time. See exactly how many people scanned your QR code and when the peak hours are.
A/B Test Destinations
Route 50% of scans to version A of your landing page and 50% to version B. Measure which converts better — then lock in the winner without touching the QR code.
Geo-Targeting & Scheduling
Show different content to users in different countries, or automatically switch the destination on a schedule — e.g., display your lunch menu at noon and dinner menu at 5pm.
UTM Parameter Support
Append UTM parameters to your destination URL to feed scan data into Google Analytics. Connect offline print campaigns to your digital funnel tracking seamlessly.
Custom Design & Branding
Add your logo, choose custom colors, and style your QR code to match your brand identity — without affecting scannability or redirect performance.
Why "Editable QR Code" Is More Accurate Than You Think
Many people search for an editable QR code thinking they want to change the pattern itself. What they actually want is the ability to change where the QR code takes people — and that is exactly what dynamic QR codes do. The pattern itself remains constant (it must, since it is physically printed), but the destination it points to is fully editable at any time through your dashboard.
This is why dynamic QR codes are sometimes called "editable QR codes" or "flexible QR codes" in marketing contexts — the term refers to the editable redirect destination, not the printed image.

The power of dynamic QR codes becomes clear when you look at real-world scenarios where updating a destination or tracking scans makes a critical difference:
Events & Conferences
Print QR codes on badges, signage, and programs. Update destinations in real-time as sessions change. Track attendee engagement at each booth or session room.
Restaurant Menus
Place QR codes on tables once. Update your digital menu for breakfast, lunch, and dinner — or swap in seasonal specials — without reprinting a single code.
Product Packaging
Print dynamic QR codes on physical product packaging. Update destinations to point to new instruction videos, warranty registration pages, or seasonal promotions.
Marketing Campaigns
Run billboard, direct mail, or magazine campaigns with QR codes. Track scan rates by location, time slot, and publication. A/B test landing pages in real time.
Retail In-Store
Display QR codes on shelf tags, window displays, and receipts. Redirect customers to current promotions, loyalty programs, or product detail pages — all updatable.
Business Cards
Add a dynamic QR code to your business cards. Change your vCard, LinkedIn profile, or portfolio URL as your career evolves — without reprinting cards.
Healthcare & Pharma
Patient information sheets and prescription packaging can link to current drug information, recall notices, and updated dosage guidelines — always current.
Education
Print QR codes in textbooks or handouts. Point students to updated syllabi, current reading materials, or evolving course resources without new printouts.
Dynamic QR Codes for Restaurant Menus: A Deeper Look
Restaurants are among the biggest beneficiaries of dynamic QR code technology. Here is how a typical setup works:
- Setup: Print one set of QR codes and place them on every table, hostess stand, and takeout packaging
- Daily updates: Each morning, update the QR code destination to that day's specials page — no reprinting
- Time-based routing: Use ScansTrack's scheduling feature to automatically show the lunch menu 11am–3pm and the dinner menu 4pm–close
- Analytics: See which tables scan most frequently, what times are busiest, and whether your menu engagement is growing week over week
Compare this to static QR codes: if a static QR code links to your old PDF menu, customers see outdated prices. You can't update it without reprinting every table card. This is why dynamic QR codes are effectively mandatory for any restaurant that takes its digital menu seriously. For more, see our guide on QR code marketing strategies.

When to Use Static vs Dynamic QR Codes
Dynamic QR codes are not always the right choice. Here is a clear decision framework:
| Situation | Use Dynamic | Use Static |
|---|---|---|
| Business cards, menus, product packaging | ✓ Best choice | |
| Marketing campaigns (print, outdoor, TV) | ✓ Best choice | |
| You need scan count and location data | ✓ Required for tracking | |
| URL might change after printing | ✓ Essential | |
| One-time personal use (share WiFi password) | ✓ Fine | |
| Linking to a permanent, never-changing URL | ✓ Acceptable | |
| No budget for a subscription | ✓ Use free static | |
| Encoding non-URL data (contact cards, plain text) | ✓ Only option | |
| Large-scale print runs (5,000+ units) | ✓ Critical — enables error correction | |
| Need A/B testing or geo-targeting | ✓ Only option |
The Business Case for Always Using Dynamic
For any professional or business use, the calculus almost always favors dynamic QR codes. Consider: a single reprint of 5,000 flyers at a print shop typically costs $200–$500. A ScansTrack subscription costs $7/month. If you avoid even one reprint per year because you could update the destination instead, the subscription has paid for itself many times over.
The scan analytics alone — knowing exactly how many people engaged with your printed marketing, from which cities, on which devices, at what times — can inform campaign decisions worth far more than the subscription cost. This is the reason professional marketers and agencies use dynamic QR codes as a default. Read more in our QR code marketing guide.

What is a dynamic QR code?
A dynamic QR code stores a short redirect URL inside the code pattern rather than the final destination URL. When scanned, the user is instantly forwarded to whatever destination URL is currently set in your dashboard. This means you can change the destination at any time without reprinting or replacing the physical QR code — and every scan is tracked with device, location, and timestamp data.
Can I edit a dynamic QR code after printing?
Yes — this is the primary advantage of dynamic QR codes. Since the code encodes a short redirect URL (not the final destination), you simply log into your ScansTrack dashboard and update the destination URL. The change takes effect immediately. Any future scans of the same printed code will go to the new destination. No reprinting required.
Do dynamic QR codes expire?
Dynamic QR codes do not expire by default on ScansTrack. They remain active and fully functional as long as your account is active. If your subscription lapses, scans on your dynamic QR codes will stop resolving. ScansTrack gives a grace period and notifications before any codes go offline, and your data is preserved if you reactivate.
Are dynamic QR codes more expensive than static QR codes?
Static QR codes are free because they require no server infrastructure — the data is encoded directly in the pattern. Dynamic QR codes require a backend redirect service and analytics infrastructure, so a subscription is required. ScansTrack starts at $7/month for unlimited dynamic QR codes with full analytics — the most affordable option among dedicated QR platforms. A permanent free plan includes 2 dynamic QR codes with tracking.
What analytics do dynamic QR codes provide?
ScansTrack dynamic QR codes track: total scans, unique scans by device, scan timestamps (date and time of day), device type (iOS, Android, desktop), operating system and browser version, country and city/region, and referral source. All data is available in real time on your dashboard. You can export data to CSV for offline analysis or connect to Google Analytics using UTM parameters on the destination URL.
