Pretty much all passports do have a chip you can read using NFC. The data on the chip is signed using a CSCA (Country Signer Certificate Authority), so you can validate the data. On most documents you can also perform a challenge-response protocol to determine the chip is authentic and not a copy (you can read the public key but not the private key). There are free smartphone apps available for both Android and iOS that let you read and verify the chip.
