One to rule them all - a single needed physical document.

Each citizen is to get a unique identification number that replaces the current JMBG, medical ID, personal ID, and driver's ID and have the new number be clearly their own and serve as their connection to the system.

Once the system is set, each citizen gets a single physical document with clearly stated primary information and a QR code that authorities can scan if a checkup or identification is needed.

Full project on Dribbble.
