Agreed, it is a misleading term. In fairness I believe some properties that have keyless entry (i.e., NFC readers where you can use your phone as your key) may actually allow you to fully check-in, but I believe that is the rare exception and not the rule. The reality is that most properties - even those technically able to do the full check-in process - want to verify your identity and confirm you are present at the property.

It should probably be better called "pre-check-in" or something, but people probably wouldn't be as apt to use it.
