Static vs dynamic QR codes
A static QR code is permanent and free. A dynamic QR code points to a short link you control, so you can change the destination after printing and see how often it's scanned.

The short answer
Use a static code when the content will never change: Wi-Fi details, a contact card, a permanent web page. Use a dynamic code when anything printed might need updating later, or when you want to know whether people are scanning it: packaging, menus, posters, signage and campaigns.
Side-by-side comparison
| Static QR code | Dynamic QR code | |
|---|---|---|
| What the code contains | The content itself (a URL, Wi-Fi details, a contact card…) | A short link that forwards to your chosen destination |
| Edit after printing | No | Yes, any time, without reprinting |
| Scan analytics | No | Yes: scans, devices, countries, unique visitors |
| Pause or schedule changes | No | Yes (scheduled changes on Starter and above) |
| Needs an online service | No, works on its own | Yes, the short link must keep running |
| Expiry | Never expires | Depends on the provider (Scansational's free one never expires) |
| Cost on Scansational | Free and unlimited, no account | 1 free per account; paid plans from US$5/month |
How a static QR code works
The information is encoded directly into the black and white pattern. A phone reads it without contacting any server, which is why static codes never expire and work offline. The trade-off: once printed, the content is fixed. A typo, a moved web page or a new menu means reprinting.
On Scansational you can make unlimited static codes with the free QR code maker, with no account and no watermark. They are generated in your browser, so details like Wi-Fi passwords are never uploaded.
How a dynamic QR code works
The pattern contains a short link, such as scansational.com/s/abc123. When someone scans it, the short link forwards them to whatever destination you have set right now. Because every scan passes through the link, the service can count scans and show which devices and countries they come from.
That makes dynamic codes the right choice for anything printed in volume or placed somewhere hard to reach: product packaging, table menus, shop windows, event signage, equipment labels. Each Scansational account gets one dynamic QR free, with no expiry and no credit card.
When to use each
- Static: guest Wi-Fi, business cards and contact details, a link that will never move, one-off personal use.
- Dynamic: menus and price lists, product manuals and warranty pages, posters and flyers, event schedules, signage in places you can't easily reach, and any campaign where you want to measure scans.
Frequently asked questions
Can I turn a static QR code into a dynamic one?
No. A static code's content is fixed in the printed pattern. To make it editable you need to create a new dynamic QR code and print that instead.
Do dynamic QR codes stop working if I cancel?
On Scansational, nothing is deleted. Your free dynamic QR and any Lifetime QR keep working; other dynamic codes pause until you upgrade again. Other providers have their own rules, so check before you print.
Are dynamic QR codes slower to scan?
A dynamic code adds one quick redirect through the short link. In practice visitors don't notice, and the shorter link often makes the printed pattern simpler and easier to scan.
Which should I use for Wi-Fi?
Static. A Wi-Fi code must contain the network details directly so phones can join without going online first.
