Plan for the paper, material and viewing conditions
A QR code that scans from a bright laptop display may fail after it is printed small, laminated under glare or wrapped around a curved surface. Start with the capacity calculator to see the actual version and module count, then use the size calculator for physical width, printer DPI and scan-distance planning. The print guide then covers quiet zones, contrast, testing and common production mistakes.
QR code not scanning?
Diagnose the problem in a sensible order: destination, quiet zone, physical size, contrast, glare, image quality, material and phone testing.
Open the troubleshooting guide →Static vs dynamic QR
Understand what can change after printing, when a redirect service is useful, and what dependency it adds to a physical code.
Compare the two approaches →Why QRivel uses static codes
QRivel is designed for simple physical workflows. For normal URL signs, WiFi cards and contact codes, the payload is encoded directly instead of forcing every scan through a QRivel redirect. That means QRivel does not need to remain in the scan path after you print. The trade-off is straightforward: if the encoded information changes, you need to regenerate the static code or keep the old destination working with a redirect you control.
Frequently asked questions
Are QRivel QR codes free to create?
Yes. The current generator and printable sign tools can be used without creating an account. Export options depend on the tool, with finished PNG/PDF signs and QR-only SVG available in the generator workflows.
Do static QR codes expire?
The static QR symbol does not contain an automatic QRivel expiry. The destination can still stop working if a page is removed, a domain expires, a WiFi password changes or another encoded detail becomes outdated.
Can I change a static QR after printing?
No. The payload printed inside a static QR is fixed. If you need post-print editing, read the static-versus-dynamic guide and decide whether a redirect service is appropriate for that use case.
What should I test before printing many copies?
Verify the exact destination, preserve the quiet zone, print at final size, and scan the physical sample with more than one phone when practical. Test on the real material and under representative lighting.
