According to Bionym CEO Karl Martin, the Nymi, sub-$100 wristband will be used to unlock cars, sign into computers, and issue payments. In accordance with many smart locks that are presently in existence, the Nymi builds off of that technology by listening in to the user’s unique heart electrical activity for authentication. Paired with a car lock or laptop login screen, it can automatically log in the wearer. It could also feasibly be used for personalized payment information that is communicated wirelessly through connected devices. According to Martin, the company has put in safety measures to ensure that people can’t get unwanted information. Though this is still a bit of ways away from reality, but speaks volumes about the future of bio-engineering and its intersection with the technology sphere.
