Static QR code
A static QR code has the destination URL encoded directly into its pattern, so the link can never change once the code is printed.
With a static code, the URL is baked into the black-and-white modules themselves. The image is the link. That makes it free and simple to generate, but it has two hard limits: you can't repoint it after printing, and it can't count a single scan, because there's no server in the middle to measure.
If the page behind a static code ever moves or dies, every printed copy becomes a dead end and you reprint. That's the exact failure a dynamic QR code avoids. Every TangoQR code is dynamic from the free plan up, so the printed image stays the same while you steer where it points.
