BundesMessenger, a secure messenger for Germany’s public administration
Germany was quite advanced when it came to technology but then the drive to make more of it somehow stopped.It has always been incredibly sad to me that the German ID card (Personalausweis) has an RFID chip inside with trust zones, certificates, authorization features, and much more and just never had been used. Like at all except for getting cigarettes at vending machines.12 years after the first RFID Personalausweis had been issued it is only possible to register your car in some cities. Maybe there are other minor uses but it's negligible.It's a very cool technology with a certificate authority and cryptographically secured claims for various things (proving you are over 18 without revealing your DOB, only giving out the name and address, authenticating as a German citizen, pseudonymity with separate identities for each service you use etc.). All functionality is also available for use over the internet.The German Wikipedia has a good overview: https://de.m.wikipedia.org/wiki/Personalausweis_(Deutschland...
