The app is a paid app. The user pays 120 tokens per year. For this, he receives information about the locations of free Parking.
The use of the information about free Parking you have to pay 1 token. The token is debited from the account automatically when the user is declared by the application location. When the user leaves the location, then the location is considered to be free. The information that the user has left the place, can be read with the help of geolocation.
Every time the user finds somewhere free Parking, ihe can inform the app. If location someone takes, who pays for that badge. Half of the token to the user, half – owners of the application. Thus application pays for itself quickly.
In the long term – the use of drones that will look out for the free Parking lot.
