Cellphones will unlock hotel rooms of the future, experts say
Hotel rooms without phone lines, art that changes in tune with your mood, even beds without mattresses. These are some of the predictions of technology futurists. Take the classic landline phone: Soon to disappear, thanks to the ubiquity of mobile technology. Not only will guests rely on their personal cellphones for calls, they'll use them as electronic "keys" that offer a contactless way in the room. A simple intercom system will allow guests to contact the front desk.
