When you use Wingocard to make a purchase, card networks like Visa charge merchants (e.g. Starbucks) a service fee - this is standard for all prepaid and credit cards, and you as the customer don't ever see this fee. This small fee is called interchange.
Wingocard receives a percentage of this interchange fee from our card network provider.
We also make money from subscriptions to access special upgraded in-app features (coming soon).
