The advancements of tech today point toward using our smartphones for just about everything. From planning, scheduling, to saving our passwords, and notes, and even making payment. Now, if you're staying at this hotel, you'll be able to use it as your room key.

The Aloft Hotel in New York City will let you do just that. Starwood Hotels & Resorts Worldwide is adding a "virtual room key" to its Starwood app in hopes that it can help make the checkin process less of a hassle.

Instead of waiting in line to get your key from the front desk, users can check in and set their payment method up on the app, and it will then become your room key,

Starwood's CEO Frits van Paasschen told The Wall Street Journal that he believes this new feature will "become the new standard for how people will want to enter a hotel." The idea might at first be a novelty, but he said that "it will become table stakes for managing a hotel."

The keyless entry uses Bluetooth and will work on any iPhone 4S or higher, and Android phones running Android 4.3 or newer.

When the Bluetooth connection in the phone comes to a sensor on the door, it will activate the lock. The locks use battery power, which means they will work even if the hotel's computer system goes down.
