At this time we only support checking accounts and debit cards from US banks/credit unions as funding sources.
When you use a Privacy card to purchase something online we automatically debit your checking account. We're hoping to roll out credit card funding, as well as other options, in the not too distant future!
For more info on adding a funding source, check out this video
Wait, I don't see debit card / checking account as an option when trying to add a funding source!
