Welcome to the new generation of carsharing: your users instantly book, open and drive one of your cars using your app on their smartphone. Convenient, simple and affordable. They can use the car for as long as they need. Once they've finished they can park the car anywhere within your predefined "Home Zone". Now let's say they need the car to run an errand outside of the Home Zone. They take the car to wherever they need and use it as if it was theirs. The car is booked and billed until they bring it back to the Home Zone where they can end their trip.
