Smartphones to Open Doors at Some Hotels | wsj.com

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. The boutique hotel brand from Starwood Hotels & Resorts Worldwide Inc. plans to offer this feature at two hotels, in the Harlem neighborhood and in Cupertino, Calif., before the end of the quarter.
