Allow instant verification via NFC

Passports have NFC chips! This means that we can read them via an app, verify the data, and thus have instant verification for users. NFC passports are also impossible to fake the data for, which massively boosts security + decreases the risk of AI-generated passports.

We could even:
- extract + cross-check MRZ/VIZ data from the passport photo page
- have liveness checks

which would help decrease fraud significantly, whilst having little friction for users.

We'd also need certificates to verify the data: you can get these with https://jmrtd.org/certificates.shtml, https://pkddownloadsg.icao.int. https://www.bsi.bund.de/SharedDocs/Downloads/DE/BSI/ElekAusweise/CSCA/GermanMasterList.html from the German BSI could be helpful too?
