How is my "change" calculated and donated?

First, you must link your "Rounding Card" and "Billing Account" to your PWI Swipe account via desktop or the mobile app. 

Once your credit/debit card(s) are linked, shop like normal and your spare change will be totaled up and donated to your nonprofit(s) of choice at the end of the month. The sum of your change will be withdrawn from your "billing account" at the end of each month and your selected nonprofit(s) will receive the funds in a quarterly check.
