There are also reloadable cards however you can't add a MP to a reloadable card until it is registered and registration requires KYC information (name, address, SSN, etc) and are only available for US residents.
They don't check identity when purchasing a reloadable card, and reportedly up to $500 (less the original load amount) can be added on using MoneyPak before registration is required. After registering, a permanent card with a higher reload limit will be sent.
