SPG App. Its going to start with the SPG hotel chain but I can imagine that most hotels will adapt to this new way of customer service. This is how getting a hotel should work! If you have the SPG app on your iPhone you can reverse a room right from the app. As you walk into the hotel your Watch will tap your wrist to ask if you want to check in. With one tap on the watch you check in and then it will show your the room number. Once you find your room all you have to do is wave your wrist near the door handle and the room will unlock and thats it. There is no need to walk up to the front desk and ask to be checked-in and be given a room key. All of this is done with just one tap on the wrist as you walk in. Another cool feature is that if you love the hotel to go for a walk around the town and you get lost the SPG app on the watch will give you walking directions back to the hotel. The future is here!
