I was thinking about that stuff too: Secure Elements, along with Ben Arc, and the Portuguese/German national ID government. It was actually related to ZeitControl and their open-source format (see: https://blogs.fsfe.org/jens.lechtenboerger/2013/04/19/how-to-set-up-your-fellowship-card/ and https://basiccard.com/). Do we think it's better to keep those wire switches in a 'black box' while keeping everything else open?
