The Sesame is a device that connects wirelessly to your computer to help protect your privacy from passersby and save you the hassle of logging on and off.

The device works similarly to keyless systems in cars. When you walk away from your computer, the device will lock it. When you get close to your computer, it will come back on. You can also define other settings for your computer to go into based on your proximity to your computer.

The device works through Bluetooth technology and it is so small that it will fit in your pocket or on a keychain.

The device costs $49.
