Le Passe-Partout (2014-2019)
In Denmark the Nem ID (Easy ID) is a cardboard master keycard printed with multiple 6 digit codes which gives acces to all official digital platforms needed to be a citizen in Denmark such as your tax affairs, the doctor, the school - pretty much everything.
Once you've used all the codes on the NemID keycard you will have a new NemID keycard, and what is left is all the used codes that sum up all your actions within a given period of time (actions which are all traceable).
A self-portrait of a kind and the story of your life.
The series is a called 'Le Passe-Partout' (The Master Key) and so far it counts 18 keycards.
