Since the midnight, no passports are needed on Czech borders and probably not even the airport. While this is another step in transmuting our post-socialist country into a full-fledged, standard democracy, I am clearly less excited than during similar events in the past.
First of all, Czechia no longer needs any "confirmation" of its current status. Second of all, the passport checks are the easiest part of crossing the border. I certainly hate complicated bureaucracy but in the case of passport checks, they might be already too easy.
The members of the Schengen zone save a few seconds with the passport check but they also lose some ability to regulate who enters the country from other member states of the Schengen zone.
