In the EU, national ID cards are required to contain fingerprints in an electronically readable section. (a private key is required to read them via NFC) As a result, Ireland started issuing passport cards, since compliant passports can be used in place of a national ID card. The only biometric data on my passport is a black and white image of my face. (that can be read with a key derived from data on the passport itself)
