The Samsung Galaxy Note 7 was unveiled earlier this month and brought iris scanning technology to Samsung’s smartphone platform. Today the Korean tech giant announced that the same iris technology has far more uses than unlocking and securing your device.

Launching in conjunction with Korean banks, the iris scanner can be used to authenticate transactions made using Samsung Pay. This does not replace the traditional fingerprint scanner, but adds to it as an additional form of unlocking the device.

“The identification through the Note 7’s iris scanner, along with the public digital authentication certificate, will be available on Samsung Securities’ mobile trading system,” explains a Samsung Securities official.

Samsung Securities, the arm of the firm responsible for the secure software such as KNOX has pushed for more adoption of iris technology in financial firms and institutions. Though the Note 7 is not the device that set-about such a demand, it definitely has been central to device security increasing and gaining more trust as a form of authentication.

Even with Samsung championing the trend, unless other device manufacturers have similar tie-ups, there won’t be enough of a demand or push for iris scanning to be used as a method of authentication.

It remains to be seen how this new technology influences consumer choices and demands and how far reaching those implications can be.
