In Asia I can't see this happening, with Hiltons you normally do have to go through the check-in process for anything in this area to work. The big exception is if it is a Digital Key hotel, mainly in North America, a handful elsewhere, where it seems that merely invoking the key is sufficient. The Digital Key is a bluetooth sub-App where guests use their phones to access their room rather than get a hotel key, and in theory it eliminates checking in at the front desk.
