Hotel service by smartphone

  LG CNS developed "smart room service" for the first time in the world, making hotel check-in service more comfortable for customers. Hotel staff can easily handle various and ongoing situations in a real time through a unified monitoring system. Customers can unlock the door and control the indoor temperature and the lights and also don't have to make a phone call to ask something. It seems what smartphone can't do is nothing. Expect what might surprise next....
