Keyforall isn't paying us to give them a plug. We like good ideas and think good ideas are worth spreading.
A smart keypad, door lock that allows you to change the code to be able to let someone inside your house or office? It's just a great idea. We might back this Kickstarter so we (a) don't have to keep keys on us and (b) give access for a freelancer or friend that needs to get in our office.
