Question 1

Which is better, static or dynamic QR codes?

Accepted Answer

Depends on use case. Static is better for one-time, permanent uses where the URL won't change (a memorial plaque, a permanent contact card). Dynamic is better for anything that might change — marketing campaigns, restaurant menus, event signage, product packaging, real estate signs. Most printed QRs that get used over months or years should be dynamic.

Question 2

Can I tell from looking at a QR code whether it's static or dynamic?

Accepted Answer

Not by looking — both look like identical black-and-white grids. You can tell by scanning: static QRs decode to the final destination URL (yoursite.com/page), dynamic QRs decode to a redirect URL (qrth.is/r/abc or similar). If the URL looks like a short link, it's dynamic.

Question 3

Do dynamic QR codes scan slower than static?

Accepted Answer

Imperceptibly. The dynamic QR adds one HTTP redirect step before reaching the destination — usually 50-100 milliseconds on a modern phone. Static QRs go direct. For users this delay is invisible; the QR scan experience feels identical either way.

Question 4

Why are dynamic QR codes more expensive than static?

Accepted Answer

Because someone has to run the redirect server forever. Static QRs are pure mathematical encoding — generate once and forget. Dynamic QRs require ongoing infrastructure: a database that stores the destination, a redirect endpoint that handles every scan, and scan analytics. QRThis offers the first dynamic QR free and $29 one-time for unlimited; competitors typically charge $5-30 per month.
