You can use our app to unlock and lock your car to start and end your trip(https://www.youtube.com/watch?v=Co0wGJxw1cM).
You can also use an RFID smartcard for the same function, see how to add your own card, such as your Leap card, https://www.gocar.ie/add-access-card/. We recommend having both options in case there is a issue with your phone signal.
