There is no need to provide an ID card or register. You can take care of everything with just a phone call. In the registry of the daily rental room that was uncovered by the police, there were only the telephone numbers of the renters and no identity information whatsoever.
What satisfied the renters even more was that the daily rental boss not only would not inquire about their origins, but also provided very thoughtful service. Except for not managing the tenants' belongings, they would provide wine if you wanted wine, and gambling equipment if you wanted to gamble.
