After adding your pickup and drop-off locations to book a ride, your payment method appears on the bottom of the booking screen. Tap on it to see a list of payment methods available to you, and simply select the way you want to pay.
You can choose to pay for your rides with cash, credit card, Careem Pay Credit, or a Careem Package. Note that you can’t change your payment method once you’re in a ride from the app but you can do this from the web. You can also contact support to help you in changing the payment method.
