There are two different types of transfers that are available to you when you log into CUOnline.
Internal Transfers: MMFCU accounts that you own will be added to your list of available accounts, so you can start making transfers between your MMFCU accounts right away. That way, if you need to make sure you have enough money in your account to cover tonight's dinner or this month's your car payment - you're just a click away from ensuring you have money in the proper account.
External Transfers: If you need to transfer money from your MMFCU account to your own account at another financial institution, you can make an external transfer. These transfers take 3 business days, and can be very convenient for those days when you can't make the drive.
