It should come as no surprise that there is an app to let you into your own home. However, if you stop and really think about it, it’s pretty freaking amazing. Phantom Smart Home’s new Keyless Home Entry system recently announced a new lock system that allows the user to unlock their door with a smartphone application. It uses Bluetooth technology and users have to set up the lock to recognize their mobile phones before they leave. It seems pretty cool until you lose your phone and you’re locked out of the house.
