Frequently Asked Questions

What is a dynamic QR code?
A dynamic QR code is a type of QR code where the destination URL can be changed after the code is created and printed. Unlike static QR codes that are fixed forever, dynamic QR codes redirect through a short URL that you can update anytime.
How does a dynamic QR code work?
When someone scans a dynamic QR code, they are first directed to our server which then instantly redirects them to your target URL. This allows you to change where the QR code points to without creating a new code.
Is this really free?
Yes, our dynamic QR code service is completely free. You can create unlimited dynamic QR codes, update destinations as many times as you want, and track all scans at no cost.
Do dynamic QR codes expire?
No, dynamic QR codes created on WebHangar never expire. As long as your account is active, your QR codes will continue to work indefinitely.
Can I track how many times my QR code is scanned?

What Makes Dynamic QR Codes Special?

The key difference between static and dynamic QR codes lies in what's encoded in the pattern:

  • Static QR codes encode the destination URL directly in the pattern. Change the URL = change the entire QR code = reprint everything.
  • Dynamic QR codes encode a short redirect URL. The actual destination is stored in our system and can be updated anytime without changing the QR pattern.

This seemingly simple difference has profound implications for businesses, marketers, and anyone who prints QR codes on physical materials.

Real-World Use Cases for Dynamic QR Codes

Restaurants & Cafes

Print QR codes on tables once, then update your digital menu seasonally, add daily specials, or change pricing—all without reprinting. Perfect for multilingual menus too.

Marketing Campaigns

Run multiple campaigns with the same printed materials. Change landing pages between campaigns, A/B test different offers, and track which physical locations drive the most scans.

Product Packaging

Add QR codes to packaging once during manufacturing. Later update to link to updated manuals, warranty registration, or promotional offers without recalling products.

Real Estate

Use the same QR code sign for different property listings. Update the destination as properties sell and new listings come in. Track which properties generate the most interest.

Events & Conferences

Print posters and flyers early, then update QR codes with latest schedules, speaker info, or live polling links as the event approaches. No last-minute reprints needed.

Business Cards

Print business cards once and use them for years. Update your portfolio link, LinkedIn profile, or company website without ordering new cards.

The Economics of Dynamic QR Codes

Consider a restaurant that prints 50 table tents with QR codes linking to their menu. With static QR codes, any menu URL change means reprinting all 50 tents. With dynamic QR codes:

  • Print once, update unlimited times
  • Change seasonal menus instantly
  • Add daily specials without reprinting
  • Link to special event menus temporarily
  • A/B test different menu layouts by updating the URL

The savings in printing costs alone can be substantial, not to mention the environmental benefit of reducing waste.

Best Practices for Dynamic QR Codes

  • Test before printing: Always scan your QR code with multiple devices to ensure it works correctly
  • Use descriptive names: Name your QR codes by purpose (e.g., "Fall 2024 Menu") for easy management
  • Maintain minimum size: Print QR codes at least 2x2 cm (0.8x0.8 inches) for reliable scanning
  • High contrast is key: Dark QR code on light background works best. Avoid color inversions.
  • Add a call to action: Include text like "Scan for menu" near the QR code to encourage scanning
  • Track regularly: Monitor scan counts to understand which placements are most effective

Security & Privacy

Our dynamic QR code system is designed with security in mind:

  • All redirects happen over secure HTTPS connections
  • We validate destination URLs to prevent malicious links
  • Only you can edit your QR codes (authentication required)
  • Scan analytics are aggregated—we don't track individual users

Additional FAQs

What resolution can I download my QR codes in?
You can download your dynamic QR codes in PNG format from 50px to 2500px using our size slider. For unlimited resolution, download the SVG version—it's a vector format that scales to any size without losing quality, perfect for large-format printing like billboards and banners.
How many times can I update a dynamic QR code?
Unlimited! You can change your QR code's destination URL as many times as you want. Whether you update daily, weekly, or yearly, there are no limits on the number of changes you can make.
Can I see detailed scan analytics?
Yes! Each dynamic QR code tracks the total number of scans. You can view this information in your dashboard. This helps you understand which QR codes are getting the most engagement.
What happens if I delete my account?
If you delete your account, all your dynamic QR codes will stop working since the redirect URLs will no longer be valid. We recommend downloading any important QR codes and updating printed materials with static QR codes before deleting your account.
Can I use dynamic QR codes for offline purposes?
Dynamic QR codes require an internet connection to redirect users. When someone scans the code, they need internet access to reach our redirect server and then be forwarded to your destination URL. If offline functionality is critical, consider using a static QR code instead.
