Meet the Elecode: a keyless door lock designed with your home security in mind. It allows you to assign up to 16 user keypad codes. Its waterproof design means you can use it indoors or outside. The battery lasts up to 2 years. You get convenient features such as anti-tampering, auto-lock, and group management.
The Fantom Elecode has a USB port for emergency power. It is immune to USB attacks though. Expected to ship in January.
