A QR code does not automatically expire just because time passes.
Whether it keeps working depends on what kind of QR it is and what happens to the destination behind it.
There are two main cases.
Static QR
A static QR stores the destination or information directly in the QR pattern.
The QR itself has no timer.
It can keep working indefinitely as long as:
- the QR remains readable
- the encoded information is still valid
- the destination URL still exists
Dynamic QR
A dynamic QR points to a managed redirect.
The QR image can remain perfectly readable, but the redirect service controls what happens after the scan.
That means a provider's expiration policy matters.
With $1 QR Codes, the QR continues redirecting to the last destination you saved even after the management period ends.
