The CIE Software (c.d. “middleware”) is the software necessary to use the Electronic Identity Card for the access to the services provided by the Public Administration.
The most common example is the access to a service of a P.A. through computer browser (Internet Explorer, Chrome, Firefox, Opera etc.) using the CIE: the user is required to enter the PIN received at the moment of the CIE request (first part) and at the moment of its delivery (second part).
The CIE Software is available here.
