Check-in process is a critical process, since a lot of vital information is exchanged between the guestand the hotel staff during this process, irrespective of the fact whether check-in process is manual or computerized. The manual process starts when a guest either walk-in (without reservation) or one withprior reservation walks into the hotel looking for desired or requested accommodation, i.e., depending
upon the availability of room the walk-in guest is assigned room whereas the guest with priorreservation is usually assigned the room for which he has requested.
