Utilizing digital design to enhance and improve the physical card without loosing visual recognizability



Through a careful design process and immense user testing, the app got its final form.



Easy onboarding illustrations and infographics provided access across age groups and tech-competencies.





Edge cases and error screens were designed for every possible scenario to avoid losing users in the process.

It's mandatory for all Danish citizens to hold a 'Sundhedskort' and therefore the app adheres to all accessibility principles, as one of the first public apps in Denmark.

Within the first week, the app secured a record-breaking 27.000 Danes registering as organ donors by using a simple notification feature when opening the app. This normally takes around +6 months.

A clear communication concept based on the iconic and recognisable yellow color and simple, bold copy highlights the core features. The material was used in the nationwide campaign.



During Covid-19 testing, the app helped remove the hassle of remembering a physical card.




The Sundhedskort App was widely adopted by Danes, harnessing 2.000.000 downloads within the first six months and used on a daily basis by more than 170.000.
