Adarsh Jayakumar, Timon Amirani and Cameron Boroumand developed a Super Secure 4 Factor Lock Box Project for their Cornell University ECE 4760 final project. It uses a typed code, 3 pots set to a specific value, a knock sensor and a finger printer sensor. All they need now is a iris scan! Of course this box is built out of something that can be smashed into with ease and the electronics take up almost all the space in the box but just imagine this built into your steel and concrete reinforced safe room in your home.
