You fixed it correctly. The player came to you and honestly explained what
happened him. If instead of forgeting the card at home he had lost it
during the tournament we would apply the same fix you applied. Since he was
between rounds there's no infraction and the player could continue enjoying
the tournament.
If he realized about the problem during the round then you should
investigate for cheating. But with this information I don't think he was.
