Bionym has developed the first wearable authentication device that utilizes a user's Electrocardiogram (ECG) to validate a person’s identity. The Nymi has two electrodes, one on the wrist and one on the top. To authenticate, a user must attach the Nymi, and then place their finger on the top electrode to complete the electric current. A user only needs to validate their identity once, until the Nymi is removed. The closed loop keeps the Nymi in an authenticated state, removing all need for repeated prompts (such as in fingerprint scanning or PIN requests).
Once authenticated, the Nymi communicates the user’s identity to a device (such as a smartphone, vehicle, elctronic lock, or even a smart environtment) using Bluetooth Low Energy (BLE). The Nymi not only uses the BLE to reliably communicate with the world, but it also uses it to sense how far away it is from devices (proximity detection). The Nymi allows users to interact with the world as a person, not as a number.
