Dynamic vs static QR codes: which one do you need?
Every QR code is either static or dynamic, and you can't switch after printing. The difference decides whether you can fix a mistake, count scans, or keep the code working for years.
Every QR code is one of two kinds. A static code stores the content itself. A dynamic code stores a short link that points to the content. You choose before you print, and you can't change the kind afterwards.
Static: the content is in the code
A static code holds the website address, Wi-Fi password or contact details directly in its pattern. A phone reads it without going online first.
- It works forever and depends on no service.
- Nobody can count or see the scans.
- It can't be changed. A typo means reprinting.
- More content means more, smaller squares, so long text makes the code harder to scan.
Good for: a home Wi-Fi password, a contact card you hand out yourself, a bank-transfer or payment code, anything that will never change.
Dynamic: the code holds a short link
A dynamic code holds something like qr.yourbrand.com/r/AbCdEf1. When someone scans it, the short link sends them to wherever you point it today.
- You can change the destination at any time, without reprinting.
- Scans are counted, with country, city and device.
- The pattern stays small and easy to scan, however long the destination is.
- It depends on the short link staying online.
Good for: menus, flyers, posters, packaging, business cards, event signs, anything printed in numbers or that might change.
Side by side
| Static | Dynamic | |
|---|---|---|
| Change after printing | No | Yes |
| Scan statistics | No | Yes |
| Works without a service | Yes | No, needs the short link |
| Size of the pattern | Grows with the content | Always small |
| Typical cost | Free | Free to start, paid for more codes |
The question to ask before you print
Will anything about this ever change, or do I want to know if people scan it? If the answer is yes to either, use a dynamic code. Most business uses are dynamic: prices change, campaigns end, pages move.
If neither, a static code is simpler and has no dependency.
What happens if the QR service stops
This is the real risk of dynamic codes, so check it before you choose a provider.
- If the short link uses the provider's domain, your printed codes depend on that company.
- If it uses your own domain, like
qr.yourbrand.com, you can move it to another service later and keep every printed code working.
In qrlia, paid plans can use your own domain for short links. Static codes in qrlia, such as Wi-Fi, vCard, email, text, phone, SMS, WhatsApp, calendar event and payment codes, carry their content directly and keep working without qrlia.
Making one
In qrlia you pick the type in the designer: Static for content printed into the code, Dynamic for codes you can edit and track. The free plan includes 3 dynamic codes.
You can also ask Claude or ChatGPT with qrlia connected: "Create a dynamic QR code for https://example.com/menu and show me the image." How to connect.
