Those options are not unique to Uber, an exiting B&H operator has a very similar system that allows customers to pay cash as well as credit cards etc.Uber is a huge move forward. For a female travelling alone, it's great that they will know the car and driver in advance, the journey will be logged and they won't have to find cash there and then. This can only be better than standing at the side of the road and flagging down a cab where nothing is known or recorded.
I'm quite sure all the B&H firms will have everything Uber offers and more shortly. Uber is actually old hat.
