Inactive Cards: Within each of your Sudo identities, you can create virtual credit cards. When you have emptied a card's value and/or refunded the card amount back to your Apple Pay funding source, your virtual card will move to the Inactive tab. Your cards will remain here until you delete your Sudo profile.
Archived Cards: Menu icon > Settings > Archived Cards. When you delete a Sudo profile, if that Sudo had any virtual cards, they move here for the lifetime of your Norton Privacy account.
