Static QR codes
A static QR code stores your data directly in the pattern. Scan it and you get exactly what was encoded: a URL, a WiFi password, a phone number. The code itself is the information.
Pros
- Never expires
- Works offline
- No third-party service dependency
- Free forever
- Perfect for WiFi sharing, vCards, and links you won't change
Cons
- Change the destination URL and you need a new code
- No built-in scan analytics
Dynamic QR codes
A dynamic code points to a short redirect URL managed by a service. You can log in later and change where that redirect goes: same printed code, new destination. Most services also show scan counts, locations, and device types.
Pros
- Update links without reprinting
- Analytics on scans
- Good for marketing campaigns where the landing page changes
Cons
- Usually requires an account
- Often paid after a free tier
- If the service shuts down, your codes break
- Does not work for WiFi or contact cards, only URLs
Which should you pick?
| Scenario | Recommended | Why |
|---|---|---|
| Restaurant menu | Static | URL rarely changes, no subscription needed |
| Business card | Static | vCard data is fixed in the code |
| Home WiFi sharing | Static | WiFi format only works as static |
| Product packaging | Static | Reliable, works without a service |
| Paid ad campaign | Dynamic | A/B test landing pages, track scans |
| Large print run with changing promo | Dynamic | Update offer without reprinting |
For most everyday uses, static is the right choice. Dynamic makes sense for marketing workflows with analytics and frequent URL changes.
