Meet the LIME Smart Lock: a neat gadget that replaces your mechanical deadbolt and lets you gain access to your home from a smartphone. The device has Bluetooth, NFC, RFID, and touch keypad access. LIME doesn’t even require you to take your phone out of your pocket to open your door.
What if you don’t have your phone with you? You could always enter a pin to enter. The app lets you grant temporary access to others. LIME has a gateway that can connect it to the Internet. More information is available on Kickstarter.
