love the idea, but if you aren't from a Shengen country you can't get into Shengen countries without a fingerprint scan and a face photo at the airport:
Those face scans are matching to the biometrics you’ve already provided to your own government when you obtained your modern passport.
My passport currently has a broken chip and I’ve been traveling extensively, so I need to go into the border guard queue every time I enter. It’s very annoying. And they take the face scan each time and their computer compares it to past images of my entry.
You can actually opt out of it. The guards will be a bit miffed but it is your right. In the EU the face scans are mandatory and the data will be retained.
