It&#x27;s curious that Optikey was posted today, because yesterday I wrote a post about the promise of iris scanning technology to deliver a seamless payments experience in VR headsets.<p>Unfortunately, none of the VR headsets shipping in the next six months have iris trackers (much less scanners). The only headset I found was Fove, which was successfully kickstarted and ships in 2016. Fove did a promotion with a Japanese school for wheelchair-bound children, in which a child played a piano using the iris tracking function of the headset.<p>There are some iris scanner-equipped phones shipping in the near future, but none with iris trackers as far as I could tell.<p>I can share the post link if people are interested.
