Future authentication methods need to be a lot harder to hack. That's the idea behind the Nymi from startup Bionym. Instead of passwords, Nymi relies on your heartbeat.

The Nymi is worn as a bracelet. It monitors your cardiac rhythm, a unique signature for each person. It is constantly authenticating your identity as it wirelessly interacts with devices. You put it on once, it authenticates you, and it keeps going until it's removed. If another person tries to use it, it will detect the different rhythm and lock that person out.

The Nymi monitors your heartbeat using an electrocardiogram sensor, but it also includes a proximity sensor and motion detector. This allows for some basic gesture controls.
