Yeah, it's old-school people control. This said, these days it could be done electronically, without the hotel storing physical information: at check-in, you put your passport in goverment-issued, (hopefully) tamper-proof machines, the hotel confirms length of stay, police server gets the info and that's it; early checkouts, the hotel must notify via some web portal. It would be relatively easy to implement.

But nobody really cares enough to spend money modernising this sort of system.
