How to change a QR code after it's printed
If you used a dynamic code, the fix takes about ten seconds. If you used a static one, the news is harder.
Whether you can change a printed QR code depends entirely on how it was made. A dynamic code points at a redirect you control, so you edit the destination and every existing print updates instantly. A static code has the link baked into the image, so the only fix is to reprint.
If it's a dynamic code
- Open the code in your dashboard.
- Edit the destination URL.
- Save. Done. The printed code now points at the new link for everyone who scans it from this moment on.
Nothing about the printed image changes, because the image only ever pointed at the redirect. This is exactly what dynamic codes are for, and with TangoQR it works on the free plan.
If it's a static code
There's no editing it. The destination is encoded in the pattern itself, so a new destination means a new pattern, which means reprinting everything. To avoid landing here again, generate a dynamic code next time and point it at your real link through the redirect.
How to tell which one you have
Scan your own code and look at the URL it opens. If it goes straight to your final destination, it's static. If it passes through a short redirect domain first, it's dynamic and changeable. Our QR URL checker shows you this without printing anything.
