The door says my ticket was transferred

It means the ticket was sent to someone else and they accepted it. The QR code you're showing is the old one, and it no longer gets anyone in.

When a transfer is accepted, the ticket gets a new QR code that belongs to the new holder.

If you sent it

You can't use it any more. The person you sent it to has the working ticket.

If someone sent it to you

You may be showing the sender's old QR, or a screenshot of it. Open the ticket from your own account, which has the new QR.

If you bought it from someone

The seller sent the ticket to a different person after you got it, or kept a copy and transferred it away. We can't undo that at the door. Contact the person you got it from.

If you didn't send it to anyone

Someone with access to your account may have sent it. Tell the door staff, then email support@daytona-lab.com with the event name and the email on your account.
