When you use Authorize only, the payment is held but not yet charged — you'll need to capture it to actually collect the money. If you don't capture it in time, the hold is released back to your customer's card. A card reader or Tap to Pay hold lasts at least 2 days (5 for Visa); a typed card's lasts about 7 days. Need longer? See Extended authorization. It's just like a hotel placing a hold on your card for incidentals.
You can capture a payment two ways: in the app, open the menu, go to Payments, and swipe the uncaptured payment to capture it (or open it and tap Capture) — or from your Stripe Dashboard at dashboard.stripe.com/payments.
