What does "Uncaptured" mean?

When using the Authorization Only feature within the app, you will need to manually Capture the payment within 7 days or the funds will be released back to the card holders credit card. This is a similar situation to what happens when staying at a hotel, and they put a "hold" for incidentals on your credit card.

You can Capture payments from the app by navigating to the menu, then Recent Charges and swiping recent charge rows to the right, or in your Stripe Dashboard at: https://dashboard.stripe.com/payments.
