Field notes
The site frames card management as a record of stored payment methods rather than a history of transactions. Its examples include annual fees and domain renewals, which may not appear in recent activity. The guide also describes moving all or selected registrations to another card, including temporary switches followed by a move back. The homepage recommends backing up data before clearing browser storage.
