One of the App Store Foundation's goal is to make AppCoins available for everyone, and that's why users that don't own APPC can make payments with credit cards.

Below you can see a live log of express conversion exchange transactions. Every time a user makes an in-app purchase with a credit card, we will convert the fiat currency into APPC via (Conversion). Those APPC will then be transferred to the BDS account (Withdrawal). You can see all of these transactions in this page.
