Bluetooth Smart padlock without physical keys, just remember to bring your cell phone before you go out.

According to SlashGear, Kickstarter has an interesting project called Noke.

Noke is a Bluetooth smart padlock, its external without any physical buttons, unlock is through the smart phone to achieve. Noke offers an adaptive Android and iOS app that allows users to assign an ID to each door lock after pairing is complete.

The project's launch team Fuz design thinks the key will be intelligently sooner or later, and the padlock is the beginning.

When you need a lock, just tap the screen padlock to activate from sleep mode and start searching for the Bluetooth connection. It automatically bounces off when it detects a smart phone that matches it. Noke also prepares a manual unlock code to avoid embarrassment, given the occasional embarrassment of running out of battery or without a cell phone.

Noke is currently on the Kickstarter, although nearly one months from the end of the event, but it has raised more than 100,000 U.S. dollars, completed the previously set goals.
