I just visited Italy. We absolutely passed through biometric scans on arrival and departure from FCO (US passports, vacation so no paper visa).

And then again at DUB outbound (US pre-clearance, so the normal Global Entry kiosk).

All of this was expected. The only thing that surprise me was there was no passport check or any other custom/immigration at Dublin on the inbound leg. We just walked from the arrival gate to the departure gate and that was that.

Ireland is not in Schengen, so you were doing an international-to-international transfer. You normally don't have to go through immigration and customs for those, unless there are specific legal requirements or the airport is poorly organized.

Sure, but we went down the same hallway as everybody who was stopping in Ireland. There was just a sign at passport check with an arrow that said go on by. If I had wanted to stay in Ireland, I could’ve just walked out of the airport.

Pre clearance from the US means nothing for Ireland, it's also not Schengen.

Because you've done it on your outbound. Ireland is also a bit more relaxed, but at the same time they can randomely ask you for your papers.

If you don't pass the control, if I'm not wrong you'll never need to be rechecked. The only place it has happened to me within EU was between Ireland -> Germany -> Greece. Probably because Ireland isn't Schengen

Dublin is amazingly chill with passport/visa/immigration.

I once needed an actual stamp in my passport, and the agent literally apologized to me for taking up the space. I thought she might be messing with me, but not, entirely serious.
