How might we create a unified platform that covers all ID card-related activities, including administrative functionality, document encryption and digital signatures for all ID-card holders in Estonia?

Responsibility area

User research, ideation. The delightful visual design is made by Hedi Haljand. Prototype by Vjatseslav Fjodorov.

DigiDoc is the official application for the citizens, inhabitants and e-residents of Republic of Estonia to use their ID-card electronically:

Encryption? I think I know what it is but cannot really explain. No... tell me.

― Office worker

I sign around 20 documents digitally per day and don't even think about the process. I do understand the technology behind it but it might not be the case for a regular user.

Users

600 000+

The main goal of this project was to design a unified platform for all ID-card holders of Estonia. This means a growing user base of 600 000. The whole design got a direction through defining 5 biggest target groups, including our grandparents and tech-savvy IT-kings.

The biggest challenge here is providing all the necessary functionality for professional users while keeping the UI minimal and understandable for tech-timid users. Some of the solutions included a reviewed terminology and tone of voice, thorough onboarding experience, as well as accessibility considerations.
