Paying for stuff with your wrist in Australia is damn-near impossible. Nobody wants to bring their payment product out here! That's why this heartbeat payment tech raised our eyebrows. Meet the Nymi Band.
The Nymi Band is like a contactless credit card, which only works when you (and only you) are wearing it. It uses a sensor to record the electrical activity of the wearer's heart, the same kind of thing a hospital uses during an ECG.
That electrical activity is apparently unique to each individual, which allows Nymi to build a 'Heart ID', which is used to authenticate the wearer and allow them to make payments using NFC, the same technology that powers contactless credit cards (and Apple Pay).
It sounds like a pipe-dream technology, but Nymi actually has a trial up and running for Canadian Mastercard users who bank with TD. The trial will expand to more Canadian banks later this year.
But I don't think that you'll be seeing the Nymi Band in stores any time soon -- far more likely is the technology being integrated into smartwatches, which already have most of the sensors and smarts to pull the trick off.
