An American chain of hotels and resorts named 'Starwood' has enabled visitors to use their smartphone as hotel keys. This new system will turn your iPhone into your room key so you can have faster and easier access without the need of an actual key.
All you have to do is download the hotel smartphone app to your iPhone where you have access to the hotel keys and benefits. This allows the visitor to have a piece of mind and convenience of accessing all the hotel features during their stay. When using the iPhone app, all you have to do is scan the door with your phone. This concept is still under development but will also be available for Android devices as well.
