Actually it does. Biometric passports (and IDs) have a chip which is read via NFC and the information the NFC provides is signed by a CA which is the government that issued the passport. ICAO compiles a database of public keys corresponding to each government (plus countries exchange their public keys via bilateral agreements). Unless somebody is doing purely visual inspection, any time a passport is scanned there's PKI involved to validate if the information is genuine.
