The system runs a custom-built Real Time Operating System (RTOS) with a suite of cryptographic solutions for keeping data secure and messaging with friends or super-secret spies that also have Vault. Google wants it to be as user friendly as possible so the host does all the work without the users having to deal with configuring the device.

The company also showed off a security protocol that determines who you are based on your habits. It takes your input and creates a "Trust Score" as to how certain it is that you're the owner of a device.

The card and system are still "very much in the experimental stage" with 500 seeded internally at Google. But, the source code for the system is available so developers can start delving into it.
