The iris of your eyes, your heartbeat and your body’s unique scent are just three new methods of biometric identity that are being introduced through various technologies.

But now, different technologies being developed incorporate other biometric elements that are equally infallible, such as body scent, the ocular iris, facial recognition, heartbeat and ultrasound.
