PermaQRDynamic QR codes with no expiration
Short answer: a dynamic QR code expires when the company running its redirect stops running it. That usually happens when a free trial or subscription ends. To avoid it, use a static code (if the link will never change) or a dynamic code you pay for once.

How a dynamic QR code works
A static QR code contains your actual link, for example https://yourcafe.com/menu. Phones read the link straight from the pattern, so it works as long as that page exists.
A dynamic QR code contains a short link owned by the QR provider, for example getpermaqr.com/q/abc2345. When someone scans it, the provider’s server redirects them to your page. That is what lets you change the destination after printing. It is also the weak point: if the provider stops redirecting, your printed code goes nowhere.
Why dynamic QR codes "expire"
- The free trial ended. Many generators let you create dynamic codes during a trial. The code works while you test it and stops later.
- The subscription lapsed. Plans renew monthly or yearly. A failed card or a cancelled plan can mean the redirect stops.
- A scan cap was reached. Some cheaper plans limit scans per month or in total.
- The provider shut down. Less common, but possible with any hosted service.
How to check before you print
- Scan your code and look at the address that opens first. If it is the generator’s domain, it is dynamic.
- Read the plan terms for the words "trial", "deactivate", "scans per month" and "renews automatically".
- Ask the provider what happens to existing codes if you stop paying. Get the answer in writing.

Questions
Is there a dynamic QR code generator that doesn’t expire?
Yes. PermaQR sells dynamic QR codes for a one-time payment. There is no subscription, so there is nothing that can lapse and switch the code off.
Why do most dynamic QR codes expire?
A dynamic code points at the provider’s short link. Many providers only keep that redirect running while you pay a subscription, and stop it when a trial or plan ends.
Are free dynamic QR codes safe to print?
Check the terms first: many free plans cap scans or deactivate codes after a trial. If the code is going on something expensive to reprint, use a static code or a dynamic code you paid for once.
How long does a PermaQR code last?
There is no expiry date. If the service ever closes we commit to at least 12 months’ notice and a full export of your codes and links.
