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.
Ironically, that would enable tracking much more than the normal case, which is a hotel stores the scans on a hard drive on the closet that nobody every looks at unless they get a subpoena.

Are you 'avin a laugh mate?
A photocopy of my passport is going nowhere and is shreadded afterwards. An electronic copy..... God lord.
The GDPR also requires data deletion once you no longer need it; physical as well as electronic. This is common sense, and why some organisations don't do this is simply mind boglling.
All these giant data leaks are coming from the government's "tamper proof" systems!
I'm sure they're done electronically in some places: Your passport details are appended to the shared Google Spreadsheet...
I'm only half joking: I used to work in payments, hotels didn't care about PCI. Full card numbers stored everywhere.
