The hotel check-in process has been the same for 100 years
The hotel check-in process is practically the same as it was a hundred years ago. Hotels require guests to register, which involves the guest providing or confirming personal information, including contact information and a signature. The process is so old, so no one knows why the same process is still there. Most likely, the method originated because of legal reasons. Kings and rulers wanted to keep track of where people traveled. Most countries still require hotel guests to provide information.
