Expiring codes
Codes that stop when they should
Give a code an end date and it stops resolving after it, sending late scans to a safe page instead of a stale destination. Set the window once for campaigns and compliance deadlines that have to end on time.
What is an expiring QR code?
An expiring QR code is a dynamic code with an expiry date attached. Before the date it behaves like any other code and forwards scans to your destination. After the date it stops resolving, so the link cannot quietly keep working past the point you intended it to end.
What does a scan show after expiry?
The scan stops forwarding to the destination and lands on a safe page that says the code is no longer active. That is the point: an expired promotion or a withdrawn document should not keep sending people to an old page, and a hard stop is safer than hoping nobody scans the leftover print.
When are expiring codes useful?
For anything time-boxed. A promotion with a legal end date, a link for a single event, or a document that should stop being reachable after a review window all map cleanly onto an expiry. You set the date up front and the code enforces it without anyone remembering to switch it off.
Can I change the expiry after setting it?
Yes. The expiry lives on the live code, so you can extend it, pull it in, or remove it entirely. As with every edit in redireo, the printed image stays the same — only the behaviour behind it changes.
Expiring code questions
What is an expiring QR code?
It is a dynamic code with an end date. Up to that date it resolves normally; after it, the code stops sending scanners to the destination. You use it when a link should only be live for a fixed window.
What does a scan show after the code expires?
The scan no longer forwards to the destination. Instead of a stale or wrong page, the scanner lands on a safe page indicating the code is no longer active, so an expired campaign cannot keep sending people somewhere you have moved on from.
Why would I want a code to expire?
Time-boxed campaigns and compliance windows. A promotion that legally ends on a date, a temporary event link, or a document that should not stay reachable past its review period all benefit from a hard stop you set once.
Can I extend or remove the expiry later?
Yes. The expiry is a property of the live code, so you can push the date out, bring it forward, or remove it. The printed image never changes when you do — only when the code stops resolving.
