NFC ISO7816 for ePassport
You should start by checking the error returned when your reader session is invalidated.
You say all setup is done, assuming correctly, but that's where mistakes are most commonly made, by not including the correct entitlements, and declaring the AIDs you need to use with the passport.
Also, reading passports is not going to be as simple as reading a regular NFC tag by just tapping. They will usually be protected by an access protocol.
You will need to determine the protocol used by the passport you are trying to scan. Older passports use BAC (Basic Access Control), where newer ones may be using PACE (Password Authenticated Connection Establishment).
In your app, you need to have implemented the correct protocol both in code and in user flow.
