Implantable RFID company Dangerous Things looks outside the body with hacker-friendly Bluetooth switch

Amal Graafstra is used to hacking things to work for him. He has two RFIDs implanted, one in each hand, that he uses to unlock doors, start his motorcycle and log into his computer. But Graafstra and his Seattle-based company, Dangerous Things, want to bring hackers more tools to bend the environment to their will. The first tool is the Switcheroo, a tiny Bluetooth circuit board that can interact with microprocessor controls. That means it can perform tasks on thermostats, vehicle keyfobs and even appliances — things like altering temperature in a room or opening a car door with your phone.
