Somebody cannot come and wants to give their seat to a friend. A transfer moves the ticket rather than voiding and re-issuing it.
Raising an offer
From the order's attendee table, press Transfer on the row and enter the new holder's email and name. They get a claim link.
Nothing changes until they claim
The original holder's ticket keeps working, and they can still walk in. That ordering is deliberate: voiding the seat at offer time means an ignored transfer email strands a paid ticket nobody can use and nobody notices.
You can withdraw a pending offer at any time.
What the new holder does
They open the link, give their own name, optionally a phone number, and answer any per-ticket questions the event asks. Their answers replace the previous holder's — a t-shirt size belonging to somebody who is not coming is merely wrong, and an emergency contact belonging to them is dangerous.
On submit the ticket becomes theirs, and the previous holder's link stops working.
Turning transfers off
Some events cannot allow them — a ticket priced for defence personnel, a rate tied to a named individual, an event whose terms say tickets are non-transferable.
Clear Allow ticket transfers in Event details and no new offer can be raised on that event, by a holder or by you.
An offer already waiting still goes through
Turning the switch off does not withdraw an offer somebody has already been sent. They have been told a ticket is coming, and silently stranding the seat helps nobody. Withdraw those individually first if you need to.
The rules
The one thing to know about the QR
The QR code does not change. That is why an offline scanner with an already-downloaded list still recognises the ticket — a re-issued ticket would carry a code the list had never seen, and would be refused at the door with no way to check.
The old QR image keeps scanning too
The copy of the QR already sitting in the previous holder's inbox is the same code, so it still scans. Single-use check-in is what stops it being used twice: whoever arrives first is admitted, and the second is refused as already scanned. For that reason a transferred ticket is emailed to its new holder as a link only, so a second permanently-valid image is never created.
If the name at the door still shows the previous holder, the scanner is running on a list downloaded before the claim. Refreshing it picks up the change.
