IO changes the way public services are delivered, putting the citizen at the center of the relationship with entities and institutions. Even today, too often, citizens have to go to a public office, or untangle their way through dozens of digital platforms to figure out how to access the services of the various public entities and manage their related obligations to the state. With IO, the administrations contact the citizens through a single app, enabling them to manage operations related to a specific service quickly, punctually and securely from the comfort of their smartphone or tablet.
