Sesame claims to be the best of the smart locks out there–with a simpler app, faster activation time, and no hard installation required (no screwdrivers or hammers needed). If you’re too lazy to take your phone out of your pocket, the Sesame app utilizes the accelerometer in your phone by letting you knock on your phone while it’s still in your pocket. That same coded knock can be used on the door itself. Sesame also comes in about six different colors, because why not? Here’s a few other smart locks on the market that are helping to make a keyless world. Most of these locks rely on bluetooth and wifi, so no worries about being locked out if your internet goes bye-bye. Normally, I refuse to use cliche phrases like “wave of the future,” (pretend I used something else that means the same thing) but it seems fitting for these devices. Image Credit: Flickr/Moyan Brenn
