QR codes are everywhere โ restaurant tables, shop counters, product packaging, visiting cards, posters. When you create one, many websites ask you to choose between static and dynamic, and some quietly create dynamic codes that stop working when a free trial ends. Hereโs what the difference really means for your business.
How a static QR code works
A static QR code is simply your data โ a website link, a phone number, Wi-Fi details or plain text โ converted into a pattern of squares. When someone scans it, their phone reads the data directly from the pattern.
- โ Free to create and use
- โ Never expires โ the data is in the image
- โ No middleman โ nobody can switch it off or redirect it
- โ Private โ no third party sees who scans it
- โ Canโt be edited after printing
- โ No built-in scan statistics
How a dynamic QR code works
A dynamic QR code contains a short link owned by the QR provider, like qr.example/ab12. When scanned, the phone visits that link, and the providerโs server redirects it to your actual destination.
- โ Editable โ change the destination without reprinting
- โ Scan analytics โ counts, locations, devices
- โ Usually needs a subscription
- โ Depends on the provider โ if they shut down, change their terms, or your plan lapses, every printed code can break
- โ Slightly slower scans due to the redirect
A common trap: some โfreeโ generators create dynamic codes by default. Months later, after thousands of menus or packaging labels are printed, the codes stop working until you pay. Always check what kind of code you are getting.
Which should you use?
| Use | Best choice | Why |
|---|---|---|
| Restaurant menu link | Static (to your own page) | Update the menu page itself, not the code |
| Wi-Fi for guests | Static | Wi-Fi details rarely change |
| Visiting card | Static | Contact details and website are stable |
| UPI or payment page | Static | Must always work; no middleman |
| Short-term ad campaign with A/B testing | Dynamic | Editable destination and analytics matter |
| Printed packaging for years | Static (to your own domain) | Avoid dependence on a third party |
The best of both: static code + your own website
You can get most of the flexibility of dynamic codes without a subscription. Point a static QR code at a page on your own website โ for example yourshop.com/menu. If the menu changes, you update the page. If you want statistics, add tracking parameters to the link, such as ?utm_source=qr&utm_medium=table, and your website analytics will show how many visits came from the QR code.
Printing tips so codes always scan
- Size: at least 2 ร 2 cm for close-up scans; larger for posters read from a distance.
- Contrast: dark code on a light background. Avoid light-on-dark or low-contrast brand colours.
- Quiet zone: leave empty space around the code โ donโt let text or borders touch it.
- Keep the data short: shorter links make simpler, easier-to-scan codes.
- Test before printing: scan the final file with two or three different phones.

Do static QR codes expire?
No. The information is encoded in the black-and-white pattern itself, so a static code works as long as the link or data inside it is valid.
Can I track scans with a static QR code?
Not directly. A simple workaround is to point the code at a URL with UTM parameters, so your website analytics can count visits from the QR code.
Can I change where a static QR code points?
Not the code itself. But if it points to a page on your own website, you can change that page's content or set up a redirect on your site at any time.
