Thanks Mike, I have just phoned the helpdesk and apparently everything is fine. Despite what the machine said, the card is registered to me. He said it could be an issue if she tried to add a Travelcard because it clearly isn’t on a card registered to her but as long as the photocard number on the Railcard agrees to what is on the Oyster (it does, we both double checked) there won’t be a problem. He could see the discount set on the card and said it won’t disappear after 2 days which is what we were told. He also said there is no way to transfer a card to another account, we would have to cancel that card for a refund and start again with a new card (and fee…).
