I still recall what Nobel Laureate Yunus told Harsha de Silva during a television interview: the mobile was going to the new Aladdin’s Lamp, giving its user not one thing, but many. I don’t think he meant it would open doors, but that’s what this story documents:
Front pockets and purses are slowly being emptied of one of civilization’s most basic and enduring tools: the key. It’s being swallowed by the cellphone.
New technology lets smartphones unlock hotel, office and house doors and open garages and even car doors.
It’s a not-too-distant cousin of the technology that allows key fobs to remotely unlock automobiles or key cards to be waved beside electronic pads at office entrances. What’s new is that it is on the device more people are using as the Swiss Army knife of electronics — in equal parts phone, memo pad, stereo, map, GPS unit, camera and game machine.
