The lock of the future will open without a key

 Move out and forget to lock the door is the kind of thoughtlessness
 we have all made at least once . To remedy this , the company
 American Apigy invented a lock without key to lock its
 door with a smartphone application dedicated to him .
Lockitron baptized , this futuristic lock box is a self -powered
 4 AA batteries with a battery life of one year. It uses all technologies
 existing wireless communication (Bluetooth, NFC and Wi -Fi), and management
 is simply from the Lockitron application available on iOS and
 Android. The connected smartphone can then give the order to lock or
 unlock. With Bluetooth and NFC , and in possession of a
 smartphone configured, it is even possible to close the door simply by
 away from it, and open it approaching . The Lockitron is also
 equipped with a shock wave detector which sends an alert to the smartphone
 when someone knocks on the door .
 A very practical solution when you find yourself on the other side of the house or in the garden . With a lock
 classic, it is mandatory to replace when lost his keys. With Lockitron , if one loses his smart-
 phone , you just have to change the security code used by the case. This ingenious lock can also be
 combined with the conventional use of keys. It will be available in 2013 to about 115 euros.
