It’s like something out of science fiction. You walk up to your door, it recognizes who you are and unlocks it for you. We love smart locking systems, see our review of Lockitron. This new system, called August, will automatically unlock your door, and you can assign and revoke access to whoever you want. The elegant and minimalist design draws your eye to the device, even though you don’t have to ever look at it. As soon as you close your door, August knows to lock it behind you. August uses standard batteries, and lets you know when they need to be replaced. Buy ($199). Video after the jump.
