Virtual cards are digital versions of a payment card. If you order a virtual card, rather than being sent a physical card, you will not be sent anything in the post but you will be able to see your card details on your account page. You will be able to use these details to make payments online using the card. All the cards in your name on your account will draw from your main account balance.
If you have a standard account, you will be able to add virtual cards to Apple and Google Pay to use with smart devices.
Virtual cards can be ordered and ready to use within a few minutes.
