How to get that id?
Discussion
Aha, nice service. How about legality of having and using it? How about CZ ID?
It's identity card issued by a private entity that does not claim its real data.
It does not even remotely look like German id.
It's like showing someone a gym membership card. It's up to them if they accept what it says.
You can't commit fraud of course and you should not show it to the cops.
The problem in cz is that if you use it to check in at accommodation, they will instantly upload it to the cops (every provider has an app from foreign police). And they'll probably come to check.
