Samsung is believed to be working on a new advanced iris scanner for its upcoming flagship phone, the Galaxy S9. The rumor to this effect was first picked up by Korea Herald and cites its source as someone who is privy to Samsung’s efforts on this front.

While the detailed specifications are missing, what has come to the fore is that the S9 will come with a 3 megapixel iris sensor, which would be a step up from the 2 megapixel iris scanner that the present S8 duo does with.

As for the inherent benefits of having a bigger sensor, better accuracy and efficiency are surely what you can count on the most. That said, the sensor on the S9 isn’t likely to be a revolutionary development over its predecessor, the S8. So while the basic functioning of the two is expected to be largely the same, there still will be improvements in the functioning of the S9’s iris scanner.

Those will be in the form of the S9 being capable of verifying its user in more varied lighting conditions, ranging from pitched dark to dimly lit conditions. Users wearing glasses too shouldn’t have much of an effect on the working on the S9’s iris scanner, nor if the user isn’t directly looking at the scanner or even if his or her eyes is gazing around.

Worth mentioning, the iris scanner on the present S8 and S8 Plus has proved to be one that can’t be relied on given that there has been instances of it being fooled by printed images on a couple of times. Fortunately, the feature is backed up by other authenticating technologies such as fingerprint scanner along with the usual pattern and PIN matching tech.

Also, needless to say, the S9 is also likely to feature the tried and tested fingerprint scanner though let’s not forget Samsung has also sought a patent on a palm scanning feature as well. Though the company has called its palm scanning feature as a means to retrieve lost password, the same can well be used to authenticate users as well.

Meanwhile, all of this assumes significance in light of Apple adopting the more innovative Face ID tech though the same has also been found to have its own limitations as well. As such, it will be interesting to see which of these wins the race, Face ID or iris/fingerprint scanner being pursued by Apple and Samsung respectively.
