Skip a heart beat, seems we all have a unique heartbeat rhythm! A new wristband technology called NYMI is using it to identify people.
The wristband relies on authenticating identity by matching the overall shape of the user’s heartwave (captured via an electrocardiogram sensor). Unlike other biotech authentication methods — like fingerprint scanning and iris-/facial-recognition tech — the system doesn’t require the user to authenticate every time they want to unlock something. Because it’s a wearable device, the system sustains authentication so long as the wearer keeps the wristband on.
