@Johann150 Nearly everyone has a provincial health card as well, which can be used as identification if absolutely necessary (e.g. police encounter), and you could use your passport for opening a bank account or anything else like that
@jbauer hmm i see. though in germany i've had problems sometimes when i used my passport because it doesn't have a street address on it, which the id card has. i guess its similar with other passports too. and of course the passport is much bulkier than the id card.
(my id card expired but passport had just been renewed because of international travel, so i didn't get a new id card for ~2 years, also because i was about to move to a new place anyway which would have been more hassle to change the id card again)
