Hotels often invest in technological solutions to attract customers.

Hilton will invest 550 million dollars worldwide for the card system used by customers to unlock the rooms to be replaced by mobile apps for smartphone terminals. The Hilton representatives say the smart system will be in operation all over the world until 2017 so customers will not even have to take care of the card.

In addition, they can send offers and better interact with tourists. Also, the application can help you find the nearest Hilton and will take you back to the hotel in case you got lost.
