To those who've used Uber before. How's payment secured? For example, I ask a cab, the cab comes I get in, he brings me to my destination. Is there a moment that I need to confirm I took the ride and the payment is made? If so, when 's that? Is it like a confirmation I do on my phone which the driver receives immediately? What if your phones battery is empty during the ride?
You open the app and you get a picture of how many uber cars are in the area (you also get a estimate of your trip, you may even save your frequent destinations). Then, you request a car and you get a message telling you which driver and car u will get. Once, you step in, I assuming the driver confirms (but notes sure). You get to your destination and receive a mail or a text with payment info a few mintutes later. You have the option to rate the driver. It is well done and super convenient. When u sign up for the app, that is when u enter your cc info.
Basically, once you request the car, you have nothing else to do.
