"There are a couple of hundred different passports issued by a variety of countries and organisations." Judging from the linked Wikipedia page there are even more. Because at least in the case of Germany what you see is a "Reisepass" that is commonly used for traveling but when you are to prove your identity typically you use your "Personalausweis" which is a small plastic card like a credit card. As far as I know many countries have similar identity cards. https://en.wikipedia.org/wiki/Identity_document https://en.wikipedia.org/wiki/Identity_document
