Guests arriving at the Aloft Hotel in Manhattan or one in Silicon Valley will soon be able to do something hotels have dreamed about offering for years: walk past the check-in desk and enter their rooms by using a smartphone as a room key.

Guests at these properties will receive a message on a Starwood app containing a virtual key, which will unlock the door with a tap or twist of their phone through the use of Bluetooth technology. The company says the iPhone 4s or newer models and the Android phones running 4.3 or newer will be compatible.

Personally, I still enjoy the interaction with staff members when I check in, which is also the reason why I always go talk to an employee when I need to buy something at my local Apple store (I tried Apple’s EasyPay feature, and it felt odd).

This is where the future is going, though, and there are several elements worth considering. Bluetooth LE has stolen the spotlight from NFC for low-power, peer-to-peer wireless transfers, and there are obvious security concerns over solutions like this, as well as home products like the Lockitron. It’s an exciting time to watch pocket computers reshape our world.
