At HostArmada, you are welcome to use as many cards as you would like to. The one which is marked as a “default” one will be used by the system whenever an automatic renewal is due.
In order to reach the menu where you can add additional cards, you need to select the “My Account” option and, afterward, “Manage Credit Card.” Once you go through this path, you will be presented with an option to “Add New Credit Card.” Each of the credit cards you have added to your account will have a button “Set as Default” on the right side of the screen. Once you’ve chosen a default one, it will be the one that will be used for automatic payments.
Whenever you want to use another card instead of the one you currently have selected as a default one, simply select the “Set as Default” option right next to that specific card.
You can see the different options painted with red arrows here:
