When you request a trip with your debit card, credit card or Paypal, we will pre-authorize your payment method, that amount will be the same as the estimated fare of your trip. This is a pre-authorization and not a definitive charge for your card so don't worry if you get a notification from your bank with a payment authorization.
If the trip was canceled or the total fare isn't the same as the initial price in your app, the retention of authorization will be canceled in your payment method in a few business days depending on the regulation of your bank. If you want to confirm a specific item in your summary, contact your bank directly.
