Halifax testing heart sensor to replace banking passwords

A proof of concept experiment by Halifax used a electrocardiogram band to pick up unique rhythms from its users’ heartbeats. This was in an attempt to replace their banking passwords.
The technology, known as a Nymi Band, uses Bluetooth to pair with a companion app for Windows, Mac, iOS and Android. In order to work it first has to record a person’s ECG to the band and link itself to the app. ECG data is captured when the customer wears the band on one wrist and touches a sensor on the top of the band with their opposite finger.
