Passengers simply need to enter the badge number into the HailoPay site. It is releasing a new mobile payment service that will be made available to all London black cabs , which reports suggest will allow them to compete more effectively with Uber . The service will allow all black drivers in London to support cashless payment through a mobile app ; for the service to work , it does require that the driver downloads HailoPay . Each driver will also have to individually sign up to Hailo 's service , but as 15,000 of 22,500 London black cab drivers have already signed up , this should not impact the offering of the service too heavily .
