The IO app provides a user-friendly interface for interacting securely with various Italian public administrations, both local and national. Users can access a range of services, receive important communications, and manage payments all from one platform. The app allows the addition of personal documents to a digital wallet, ensuring they are readily available on the device. Users can also receive legally significant messages from public entities and keep track of deadlines related to public administration.

Moreover, the IO app simplifies payment processes by enabling users to pay any pagoPA notices via QR code or messages received within the app. Receipt downloads are also possible even if payments were made outside the app. Accessing IO is straightforward, requiring SPID credentials or electronic identity card options, with secure authentication methods like PIN or biometric recognition to enhance user security.
