Samsung didn’t get fingerprint scanner technology into the Galaxy Note 3, but from the sound of it, the company was still interested in the idea, and once it worked things out, we’d see it on a future phone – maybe the Galaxy S 5? Well, that’s one theory, but this evening we caught wind of claim that Samsung could deliver something a little different from the biometric authentication shop, giving the GS5 an iris scanner.
For the record, the sourcing of this rumor is pretty shaky, and we don’t have any particular reason to put a lot of faith in it.
That said, the idea of iris scanners on phones in general is pretty intriguing. On first glance, it sounds plausible even, but the more we think about it, the less sense it makes. For one, you’re not only going to need a high-resolution front-facing camera, but one with some decent optics. That not only means expense, but space, and the combination might be too much to ask, especially with front-facers going underused in general.
Our thoughts also flash back to the problems with Samsung’s existing efforts in eye-tracking, and remind us of another big issue: this isn’t going to function too well at all in low-light environments. Even extra illumination might not be a fix – users aren’t going to want to shine a bright light in their eye each time they need to authenticate.
All things considered, this one doesn’t sound too likely, though we’ll certainly be looking for any signs that show up down the road in future GS5 leaks that might just have us thinking twice about that.
