Smartphones have effectively replaced a lot of the gadgets that we used to buy, including calculators, compasses, alarm clocks and dedicated GPS trackers. And now The Wall Street Journal reports that smartphones look poised to kill off another antiquated piece of technology — hotel key cards. Per the Journal, Hilton is planning to implement technology that will let its guests use their smartphones to open up their hotel rooms starting next year. The new integration of smartphones as hotel keys is part of a $550 million investment that Hilton is making to make it easier for guests to use their smartphones not just to unlock their rooms but to pick out their rooms and to check in and out of hotels.
