The e-Citizens' system is launched with the aim of modernizing, simplifying and accelerating citizen and public communication and increasing public sector transparency in providing public services.It consists of: a personal user compartment, a central state portal, and a National Identification a-nd Authentication System (NIAS). The Government of the Republic of Croatia has concluded a contract with APIS IT, which includes the development of a system for receiving messages, creating web and mobile applications of the OKP, maintaining and hosting the system, and improving all over the next three years. The e-Citizen is becoming logged in to the system with the username and password with which they will be notified later. You can make an application at FINA or via the Internet. Also, we must mention that a user is made available if the person is over 15 and has an OIB. What gives us the e-material system is a better and faster compaction when enrolling in high school, patient orders, supplementary insurance, insight into the labor market and so on. It is important to emphasize that e-citizens have personal information available only to the user. E-Citizen Builders are: Increasing Government and Citizen Interaction, Encouraging the E-Passenger to Use ePass and eToken citizens, making transparency in Government governance processes, improving government accountability to citizens, reducing costs and investments that otherwise go to paperwork and stationary, reducing reaction time and waiting lists.
