Question 1

What is the difference between a dynamic and a static QR code?

Accepted Answer

A static QR code embeds the final destination URL directly into its pixel pattern — once printed, it can never change. A dynamic QR code encodes a short redirect URL instead, so you can update the destination anytime through a dashboard without altering the code itself. Dynamic codes also collect scan analytics (location, device, time), while static codes provide no tracking. The trade-off is that dynamic codes require an active subscription to maintain the redirect, whereas static codes work indefinitely with no ongoing cost.

Question 2

Can I convert a static QR code into a dynamic one?

Accepted Answer

No. Because a static code has the final URL baked into its pattern at the pixel level, there is no way to retroactively add a redirect layer. You would need to generate a new dynamic QR code and replace the printed static one. This is why many businesses choose dynamic codes from the start — even if they do not plan to change the URL immediately, having the option and the analytics makes the small investment worthwhile.

Question 3

Do dynamic QR codes expire?

Accepted Answer

Dynamic QR codes remain functional as long as the redirect service behind them is active. On QR-Hero, your codes stay live for the duration of your subscription. If your subscription lapses, the redirect stops, but the codes are not deleted — reactivating your account restores them instantly. There is no built-in expiration date on the code itself.

Question 4

Are dynamic QR codes slower to scan than static ones?

Accepted Answer

The camera decodes both types in milliseconds. The only difference is the redirect step after scanning: the device makes a quick network request to the redirect server before reaching the final page. On QR-Hero, this redirect adds roughly 50–100 milliseconds, which is imperceptible to users. In practice, dynamic codes often scan faster because their shorter encoded URL produces a simpler pattern that cameras resolve more quickly.
