Earlier quoted context omitted.
I think American passports have those as well because I remember all the hax0rs making videos showing where to smash the NFC chip with a hammer or to buy wallets with special NFC blocking properties to keep folks from “stealing their identity” from the NFC chip. Personally I never cared but your comment jogged a memory. Recently I added my passport to my Apple wallet but I’m not sure if that’s used anywhere.
On US passports stealing the identity is a possibility as the chip in US passports do not implement any clone detection mechanism.
I'd love to read more about what security features US passports are missing and what they have implemented. Just out of curiosity.
