A door lock is something you use everyday. Why not make the process of entering and exiting your house easier and cooler?
Sesame fits over any door lock and allows you to unlock your door with the press of a button from your smartphone. Not only does it just unlock from your smartphone but you can use a special assigned knock to gain access as well. You can also (if you are a trusting person) let your friends have access to unlocking your door to ease the burden of letting them in or making them wait for you to open the door.
Sesame is currently a project on Kickstarter and is already funded $100,000 more dollars than their initial goal of $100,000. With 58 days to go, there is still plenty of time for you to fund and help them add more features to their product such as face and voice recognition.
