Ah, sorry I was using the terms interchangeably. I think it's actually a debit setup, kind of like a gift card? I've never actually used the service, just heard some reviews about it.

Yes, you hook up your bank account to Privacy and can create debit cards. You can set them up with spending limits, and can lock them to only work with the first merchant its used with for recurring expenses (if you want). You also have the option to create one time use cards as well. For what its worth, it works well, but it seems like some merchants block Privacy cards - in my case, to buy a Grubhub gift card.
